Write the Meanings
<h2>
Answer</h2>
Atom: the basic unit of an element
Atomic theory of atoms: a theory that states that all matter is made of atoms that cannot be divided or destroyed
Element: a substance that cannot be broken down into a simpler substance
Gas: the state of matter that does not have a definite shape or a definite volume
Liquid: the state of matter that has an indefinite shape but a definite volume
Magnetic field: a region around a magnetic material or moving electric charge
Particle: a tiny piece of matter
Phase: a unique form of the existence of matter
Plasma: an ionized gas of positively and negatively charged particles
Scientific theory: an explanation for some naturally occurring event, developed from extensive observations, experimentation, and reasoning
Solid: the state of matter that has a definite shape and volume
Therefore, I hope this helps And Good Luck!
To balance a chemical equation, place coefficient as needed in front of the symbols or formulas of the elements. So the same number of each type of atom occurs in both reactants and products.
Steps to be followed are-
(1) Write down the chemical reaction in the form of word equation, keeping all the reactants on left hand side and keeping products on right hand side.
(2) Write all the symbol and formula of all reactants and products in word equation.
(3) Balance the whole equation by multiplying the symbols and formula by smallest possible figures.
Same number of each and every atom, of same type occurs in both reactants and products.
Once all the individual elements are balanced, then the total number of atoms of each element on the reactant and product side are compared once again after balancing. If there are no inequalities, the chemical equation is said to be balanced.

Answer: Empirical formula of this compound is 
Explanation:
Mass of Cr= 104.0 g
Mass of O = 48.0 g
Step 1 : convert given masses into moles.
Moles of Cr =
Moles of O =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For Cr = 
For O =
Converting into simple whole number ratios by multiplying by 2
The ratio of Cr : O= 2: 3
Hence the empirical formula is 
The most likely empirical formula of this compound is
