combined aggregation of minerals
Answers
Answer:
Rocks
Explanation:
The combined aggregation of minerals are called rocks. There are three types of rocks Igneous Rocks, sedimentary rock, and metamorphic rocks.
Rocks are formed due to the repetitive, orderly, geometrical internal arrangement of minerals. Minerals undergo several processes such as weathering, crystallization, erosion, and sedimentation to form rocks.
Hence, the combined aggregation of minerals is called rocks.

Once upon a time, Walter the water molecule was traveling around Linda's blood. He was enjoying moving around wherever he wanted. One day, Walter decided to visit some cells. He traveled in and out of the cells as he pleased. Walter decided that he liked the cells so much that he wanted to stay inside and rest in the vacuole. However, as the day went on, Walter felt a change happening around him. Linda had eaten some VERY salty popcorn. Walter LOVED Sally the salt molecule and felt a magnetic attraction to her. The closer the salt came to the cell, the quicker Walter's love for Sally pulled him out of the cell and towards the salt.

This story that is related to the movement of water in relation to the amount of solute seeks to explain the process of OSMOSIS in a very interesting way.
Explanation:
The OSMOSIS process is a process where water diffuses from a compartment with fewer solutes to one with higher solutes, that is why the osmotic intention is to balance the concentrations and molarities between both compartments, this is called osmotic balance.
For this to happen, a highly water-permeable barrier is needed.
How do cells use lipids and carbohydrates?

What is the significance of an electronegativity difference of 1.7 between 2
atoms?
O A. It tells which atoms form positive ions and which atoms form
negative ions.
OB. It represents the boundary between what is considered to be an
ionic or a covalent bond.
C. It determines if the 2 atoms will react to form a molecule.
D. It identifies which metal atoms will join together to form metallic
bonds
Am
Answers
B. It represents the boundary between what is considered to be an ionic or a covalent bond.
Further explanationElectronegativity is the ability of atoms to attract electrons, especially in covalent bonds (sharing of electron pairs)
In a periodic system, electronegativity increases in a group, from bottom to top, and in a period from left to right.
From this difference in electronegativity, we can determine the ionic compound, polar or non-polar
Pauling determined the electronegativity scale (based on bond energies), between 0.7 - 4 (Fluorine has the highest number of electronegativities: 4)
Polar covalent compounds have a large electronegativity difference, while nonpolar compounds have a small electronegativity difference.
We can use the difference in electronegativity between the 2 bonded atoms to determine their polarity
<0.5: covalent non polar 0.5- 1.7: covalent polar > 1.7 : ionExample
H₂OH = 2.1
O = 3.5
H₂O = 3.5-2.1 = 1.4 >> polar
O₂= 3.5-3.5 = 0 >> non polar
The boiling of soy oil determined by a student in the laboratory turned out to be 319.5 oC. The accepted value of this melting point is 300 oC. What is the percent error in this reading?
Answers
Answer:
Percent error = 6.5%
Explanation:
Given data:
Measured value = 319.5°C
Accepted value = 300°C
Percent error = ?
Solution:
Formula:
Percent error = measured value - actual value / actual value × 100
Now we will put the values in formula.
Percent error = 319.5°C - 300°C/300°C × 100
Percent error = 19.5 °C /300°C × 100
Percent error = 0.065× 100
Percent error = 6.5%
Theorists try to find ways to explain human behavior in rational ways. It seems irrational to break rules, if we want to maintain social order. We are largely constrained by the rules and obliged to behave in a particular way or to avoid certain behaviors. What motivates people to break social rules? Do you think powerful and famous people tend to break more rules? Is it worth breaking these rules? No Response(s) Be the first to respond to the Discussion topic!
Answers
Answer:
See explanation
Explanation:
According to Burgess (1996); 'We don't break rules because it 'doesn't feel right' to do so. Some elements of personality can determine whether we will break rules or not, particularly when the moral/social-conventional distinction is taken into consideration'.
If an individual has the urge to behave in a manner that transgresses social rules, personality characteristics now come into play here. Personality traits determines whether the individual considers him/herself as bound by the rules. Some people will follow the rules absolutely while some only follow rules that they consider important, a small proportion will not follow any rule that prevents them from achieving their set objectives.
Famous people become carried away with affluence and position and tend to break more rules since they believe that they will always get away with it because of whom they are.
Irrespective of the circumstances, it is never worth it to break a rule. We always have to see ourselves as bound by rules as part of our social responsibility.
Question
What causes a water molecule to be polar?
A. The Oxygen atom is larger and stronger than the Hydrogen atoms so the electrons spend more of their time nearer the hydrogen
B. The Oxygen atom is smaller and weaker than the Hydrogen atoms so the electrons spend more of their time nearer the oxygen
C. The Oxygen atom is smaller and weaker than the Hydrogen atoms so the electrons spend more of their time nearer the hydrogen
D.The Oxygen atom is larger and stronger than the Hydrogen atoms so the electrons spend more of their time nearer the oxygen
Answers
Answer:
The correct option is D
Explanation:
Water molecules are polar because there structures are made up two sides; the positively charged side (the hydrogen side) and the negatively charged side (the oxygen side). The atoms in the water molecule are joined together by covalent bond - meaning there is sharing of electrons between the constituent atoms. The oxygen atom is bigger/larger (in size) and has a higher electronegativity (ability to attract electrons) hence, the electrons tend to spend more time around the oxygen than the hydrogen atom.

Answer:
Explanation:
(i) Which one of these structures A to E represents a noble gas?
Noble gases have completely filled outer most orbital. It means they have 8 valence electrons. Picture D have 8 valence electrons thus it represent noble gas.
(ii) Which two of these structures represent atoms from the same group of the periodic table?
Atoms present in same group having same number of valence electrons.
Picture A and C both have one valence electron thus both are present in same group.
(iii) Which one of these structures represents an atom with an atomic number of 8?
Picture B have total 8 number of electrons it means this atom have atomic number 8. So answer is picture B.
(iv) Which one of these structures forms a stable ion by gaining one electron?
Ions are formed by gaining or losing the electrons. When an atom gain electron anion is formed. There are 7 electron in outer orbital of picture E when it gain one electron outer orbital become completely filled thus form stable ion.
(v) Which one of these structures is in period 3 of the periodic table?
Picture C have 11 electron it means this atom have atomic number 11 which represent sodium. Sodium is present in period 3. Thus answer is picture C.
Were new substances created form old substances during electrolysis? Explain.
Answers
During electrolysis a metal chemically decompose and deposits on the cathode where as the metal from the other electrode forms its ions in the electrolyte solution.
What is electrolysis?Electrolysis is the process of chemical decomposition brought out by the passage of electricity through an electrolyte in which the decomposed metal deposits on one electrode.
Electrolysis involves oxidation of one metal and reduction of the other. The prediction of the products of electrolysis requires a consideration of several factors including the potential at which the competing species are discharged at the electrode , if the electrode used are reacted or inert etc.
The oxidation reaction involves the formation of cations in the solution and the reduction involves the deposition of metallic substance at the cathode.

2. In a well-known movie, Raiders of the Lost Ark, there is a famous scene in which the hero tries to outwit the designers of a trap by replacing a gold statue with a bag of sand of about the same volume.
a) Knowing that the density of gold is 19.3 g/mL and sand is 3.1 g/mL, does this seem like a scientifically reasonable plan? Why or why not?
b) In the movie, the hero grabs the gold statue with one hand and appears to handle it quite easily. Given that the volume of the statue appears to be about 1 L, find the mass of the statue.
Answers
Answer:
I cant answer B, but I can answer A, and I don't think it is a scientifically reasonable plan.
Explanation:
The bag of sand weighs less than the gold statue, and yes the bag of sand seems like it would keep the trap from activating, but you would scientifically have to put something that was the same weight as the gold statue on the pedestal that the statue is on.
What suprising result is explained using this model
Answers
Answer:
B. A few positive particles bounced back because they were pushed away from the positive center.
Explanation:
The result of the experiment conducted by Rutherford shows that a few positive particles bounced back because they were pushed away from the positive center.
This is the central theme of Rutherford's experiment on a thin gold foil.
In 1911, Rutherford performed the gold foil experiment that gave the modeling of the atomic structure a great boost. He bombarded a thin gold foil with alpha particles. He discovered that most of the alpha particles passed through the foil while a few of them were deflected back. This led him to postulate that an atom has a small positively charged center where nearly all the mass is concentrated.Which of the following elements has the lowest electronegativity?
