Balance the following equation: Fe2(SO4)3 + KOH --> K2SO4 + Fe(OH)3
Write the coefficients that you decide to balance the equation like this 3, 4, 3. If you do not add a coefficient in front of an element or compound, use a 1 in your answer. For instance the for this balanced equation: 2H2 + O2 --> 2H2O you would write your answer: 2, 1, 2

What’s is CO written?
Answers
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!!

can someone explain in detail how molar mass, Avogadro's number, and volume are all connected through moles? Im so confused :(
Answers
Answer:
See Explanation
Explanation:
By definition, 1 mole is the mass of substance (or, formula mass in grams) containing 1 Avogadro's Number (N₀ = 6.02 x 10²³) of particles. That is ...
1 mole of hydrogen atoms (H) = 1.00794 grams
1 mole of molecular hydrogen (H₂) = 2.01588 grams
1 mole of any substance = 1 formula weight in grams
1 mole = 1 Avogadro's Number (N₀) = 1 formula weight in grams
In the concept of 'gas laws' 1 mole of any (all) gas at STP conditions ( => 0°C & 1 atmosphere pressure) occupies 22.4 Liters & is known as the 'molar volume' of a gas at STP. If the temperature &/or pressure change the volume will not be 22.4 Liters.
For reactions whose coefficients are balanced to the lowest whole number values (i.e., no fractional coefficients) the equation is known as the 'standard reaction' and conditions are assumed to be STP and the coefficients of gas phase components indicate molar volumes. Example ...
Given N₂(g) + 3H₂(g) => 2NH₃(g) is assumed to be at 0°C; 1 Atm pressure.
Molecular Nitrogen = 1 molar volume = 22.4 Liters of N₂(g)
Molecular Hydrogen = 3 molar volumes = 3 x 22.4 Liters of H₂(g) = 67.2 Liters of H₂(g)
Molecular Ammonia = 2 molar volumes = 2 x 22.4 Liters of NH₃(g) = 44.8 Liters of NH₃

OPEN ENDED QUESTION A chemistry student has a 5.001 g of CaCl2. How many moles of CaCl2 does the student have? (mm CaCl2 = 110.98 g)
Answers
Answer:
0.04506 mol
Explanation:
For this problem, you need to convert grams to moles. To do this, you need the molar mass, which is given. Divide the mass by the molar mass to find the moles you have.
(5.001 g)/(110.98 g/mol) = 0.04506 mol
3) Find the mass, in grams, of 5.08 mol Ca(NO3)2
Answers
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

What do u mean by electronic configuration? What are basic requirements while writing electronic configuration of an element (atom) ?
Answers
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:
[tex][Ga]=1s^2 2s^2 2p^63s^2 3p^6 4s^2 3d^{10} 4p^1[/tex]

Answer:
Just 1 i.e., Option B.
Because except for top of the molecule, all other sides are filled with a letter meaning there is one free space.
Answer:
B
Explanation:
H . + H . -----> H:H {":" represents a covalent bond, that is, a shared pair of electrons}
A Lewis structure is a convention used to represent the covalent bonding in a molecule. Dots or lines are used to represent
valence electrons (electrons available for bonding). The Lewis structure for the hydrogen molecule is as follows.
H:H or H-H
A bonding pair is an electron pair shared between two atoms.
A nonbonding pair (lone pair, unshared pair) is a pair of electrons that remains on one atom and is not shared.
An independent variable is

b.
manipulated by changes to the dependent variable.
C.
a variable that is kept constant.
d.
a variable that is used as a control.
Answers
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
