What determines how many of each ion is required for an ionic compounds?

please do not look up on google!!!!

Answers

Each ion has a single charge, one positive and one negative, so we need only one ion of each to balance the overall charge. When writing the ionic formula, we follow two additional conventions: (1) write the formula for the cation first and the formula for the anion next, but (2) do not write the charges on the ions.

Which has a smaller ionic radius than it's neutral atom?
A. Iodine
B.Cesium
C.Oxygen
D.Nitrogen

Answers

Explanation:

Caesium (Cs) has a smaller ionic radius than it's neutral atom.

because Caesium belong to Group 1 and It loses 1 electron. After losing 1 electron it gains 1 positive charge that's why caesium ionic radius become smaller as compared to neutral atom.

Therefore,

Option B is correct.

The heat required to raise the temperature of 12g of water from 16 C to 21 C is:
a) 60 J
b) 60 cal
c) 50 cal
d) 50 J

Answers

Answer:

The correct option is;

b) 60 cal

Explanation:

The mass of the given water, m = 12 g

The initial temperature of he given water = 16°C

The final temperature of the given water = 21°C

The specific heat capacity of water, c = 4.184 J/(g·°C) = 1 cal/(g·°C)

The amount of heat, ΔQ, required = Mass × Specific heat capacity × Change in temperature

ΔQ = 12 × 4.184 × (21 - 16) = 251.04 J

Similarly, we have;

ΔQ = 12 g × 1 cal/(g·°C) × (21 - 16)°C = 60 cal

The amount of heat required = 60 cal.

Answer:

3rd principal energy level

Explanation:

Principle energy that explains the energy of the electrons and positions of electrons of a particular atom. There are four energy levels fist to fourth that are made of sublevels and that is made up of s, p, d and f orbitals.

First principal energy level -  2

Second principal energy level - 8

Third principal energy level - 18

Fourth principal energy level -  32

3rd energy level has 9 orbitals, which has 18 electrons

2 in the s orbital,

6 in the three p orbitals, and

10 in the five d orbitals.

So, here there are only 8 electrons in the third principal energy level.

Mark is in charge of making change at his family's garage sale on a hot summer day. He runs low on change and brings out a jar of pennies from the house. He keeps the lid off of the jar. Later in the day, he notices that the pennies are hot. Which statement best explains what happened?\

Answers

Answer:

This question is incomplete

Explanation:

The question is incomplete without the options. However, when a metal (in this case what the pennies are made of) is left in direct contact with the heat from the sun, it conducts this heat and becomes hot. This process is called thermal conduction. The thermal energy is readily accepted by the material in which the pennies are made of thereby increasing the thermal energy of the penny coin  which then makes the pennies hot after being left under the sun.

C)Hyenas and lions fight over the same antelope kill.
D)A tapeworm lives in the intestine of a dog, obtaining food for itself, while slowly harming the dog.

Answers

Answer:

The correct answer is option

B) "Remora fish stick to large sharks, receiving a free ride and scraps of food the shark does not eat. The shark is neither helped nor harmed".

Explanation:

Commensalism is defined as a type of inter-species relationship at which one individual gets benefited and the other is neither benefited or harmed. An example of commensalism is the one between remora fish and large sharks. In this case, remora fish gets attached to the large sharks by an organ that acts suction cup. The remora fish gets benefited by receiving transportation, a food source and protection from predators, while the large sharks are neither helped nor harmed.

9A. A sample of hydrogen at 1.56 atm had it's pressure decreased to 0.73
atm producing a new volume of 751 mL. What was its original volume? *

Answers

Answer:

351.43mL

Explanation:

To calculate the original volume of hydrogen gas in this question, the Boyle's law equation will be used. Boyle's law equation is:

P1V1 = P2V2

Where; P1 = initial pressure

V1 = initial volume

P2 = final pressure

V2 = final volume

According to this question, the P1= 1.56atm, V1 = ?, P2 = 0.73atm, V2 = 751mL

Hence;

P1V1 = P2V2

1.56 × V1 = 0.73 × 751

1.56 V1 = 548.23

V1 = 548.23/1.56

V1 = 351.43mL

Therefore, the original volume of hydrogen gas is 351.43 mL.

What is the conversion factor used when converting mass to moles?

Answers

In such a conversion, we use the molar mass of a substance as a factor to convert that to mole units into mass units (or, conversely, mass units into mole units).

Then We also established that 1 mol of Al incorporates a mass of 26.98 g (Example). Stated mathematically that is, 1 mol Al = 26.98 g Al

                                     Molar mass

Now, This relation provides a factor to travel from grams to moles.

which is help to Using the factor 98.08 g / 1 mol: grams H 2 SO 4 = 3.60 Then mol x 98.08 g / 1 mol = 353 g H 2 SO 4
