What’s is CO written?
Answer:
CO is a chemical formula that contains one carbon atom (C) and one atom of oxygen (O). Altogether, CO translates to "carbon monoxide."
Explanation: Why monoxide and not dioxide? Well, the prefix mono means "one," and di means "two." Since there is only one oxygen atom (-oxide), then it must be monoxide! Voila!!

An independent variable is
a.
directly changed by the experimenter.
b.
manipulated by changes to the dependent variable.
C.
a variable that is kept constant.
d.
a variable that is used as a control.
Answer:
a. directly changed by the experimenter.
Explanation:
In the case of mathematical modeling, analytical modeling , and experimental sciences, the number of dependent variables based upon the amount of independent variables.
The dependent variables represent the result or outcome whose changes is being determined.
An independent variable expressed in the name form like experimental or expected variable, is a variable i.e. created in an experiment in order to verify the effect on a dependent variable
Therefore the option a is correct
3) Find the mass, in grams, of 5.08 mol Ca(NO3)2
Answer:
833.12g
Explanation:
Use the mole=mass/mr equation (rearrange this to find mass)
Mr= 164
So, 5.08 x 164 = 833.12g
The mass in grams of 5.08 mol Ca(NO3)2 is =833.12g
What is a mole?
The mole is the amount of substance of a gadget which includes as many standard entities as there are atoms in zero.012 kilogram of carbon 12;
Molecular mass of Ca(NO3)2 = 40+(14+48)*2
=40+124
= 164 g
1 mole of Ca(NO3)2 = 164 g
5.08 mole of = 5.08*164g
=833.12g

How many moles of carbon dioxide are produced when 5.12 moles of glucose undergoes a combustion reaction?
Answer: 30.72 moles of [tex]CO_2[/tex] will be produced from 5.12 moles of glucose.
Explanation:
The balanced chemical equation for combustion of glucose is:
[tex]C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O[/tex]
According to stoichiometry :
1 moles of glucose produce = 6 moles of [tex]CO_2[/tex]
Thus 5.12 moles of glucose produce =[tex]\frac{6}{1}\times 5.12=30.72moles[/tex] of [tex]CO_2[/tex]
Thus 30.72 moles of [tex]CO_2[/tex] will be produced from 5.12 moles of glucose.
An atom of an element always contains
Answer:
An atom of an element always contain three fundamental particles called electrons(e-) , neutron ( n zero) and protons ( p+)
An atom of an element always contains a proton, electron and neutron.
What is an atom ?Every atom is made up of a nucleus and one or more electrons that are attached to the nucleus. One or more protons and a number of neutrons make up the nucleus. Only the most common type of hydrogen is neutron-free. Every solid, liquid, gas, and plasma is made up of atoms that are either neutral or ionized.
But when it comes to the word atom, we must go back to 400 B.C. Greece. And Democritus, a brilliant philosopher, proposed the Greek word atomos, which means uncuttable.
Every atom is made up of a nucleus and one or more electrons that are attached to the nucleus. One or more protons and a number of neutrons make up the nucleus.
Thus, An atom of an element always contains a proton, electron and neutron.

If combining cation A with a +3 charge and anion X with a -3 charge, how would we write the compound?
O AX
O A3X3
O 3AX
Answer: it’s not A3X3
Explanation:
1. AX
For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.If a cation A carries +3 charge and an anion X carries -3 charge, the compound so formed is AX. Since the charges gets cancelled out.For example: consider aluminum phosphate, aluminum carries +3 charge and phosphate carries -3 charge, the molecular formula for the compound will be AlPO₄.Learn more:

What do u mean by electronic configuration? What are basic requirements while writing electronic configuration of an element (atom) ?
The basic requirement while writing the electronic configuration of an element (atom) is its atomic number.
Explanation:
The electronic configuration of an element is the distribution of its electrons in different energy levels around the atomic nucleus.It only requires an atomic number of an element to write its electronic configuration.The atomic number is equal to the number of protons in an atom and that is equal to the number of electrons.And the filling of electrons is done according to the Aufbau principle, the electrons will be first filled in the atomic orbitals with lower orbital energy before filling the atomic orbital with higher energy.The sequence of the atomic orbitals from lower energy to higher energy is:[tex]1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d...[/tex]
For example:
The atomic number of gallium is 31, its electronic configuration will be:

2 moles of chromium can react to 3 moles of iron (II) nitrate in order to produce 2 moles of iron and 2 moles of chromium nitrate.
If we see oxidation state, we see that chromium changes from 0 to +3
Iron changed the oxidation state from +2 to 0
Remember that elements at ground state has 0, as oxidation state.
Iron is being reduced while chromium is oxidized. Then, the half reactions are:
Fe²⁺ + 2e⁻ ⇄ Fe (Reduction)
Cr ⇄ Cr³⁺ + 3e⁻ (Oxidation)
When an element is being reduced, while another is being oxidized, we are in prescence of a redox reaction.
