Answer: The statement, chemicals that you begin with found on the left side of the equation, describes reactant and where they are in a chemical equation.
Explanation:
An equation that includes symbolic formulas and represents chemical reaction between the substances initially present forming new substances is called a chemical equation.
For example, ![N_{2} + 3H_{2} \rightarrow 2NH_{3}](https://tex.z-dn.net/?f=N_%7B2%7D%20%2B%203H_%7B2%7D%20%5Crightarrow%202NH_%7B3%7D)
Here, substances
and
are the reactants. Reactants in a chemical equation are always present on the left side as these are the chemicals we begin with.
Also here,
is the product. Product(s) in a chemical equation are always present on the right side as these are the chemicals we end with.
Thus, we can conclude that the statement, chemicals that you begin with found on the left side of the equation, describes reactant and where they are in a chemical equation.

Answer:
Lithium Fluoride.
Explanation:I know science.
Answer:
450.0 L.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and T are constant, and have different values of P and V:
<em>(P₁V₁) = (P₂V₂).</em>
<em></em>
V₁ = 760.0 L, P₁ = 450.0 mm Hg,
V₂ = ??? L, P₂ = 760.0 mm Hg (standard pressure = 1.0 atm = 760 mm Hg).
∴ V₂ = (P₁V₁)/(P₂) = (760.0 L)(450.0 mm Hg)/(760.0 mm Hg) = 450.0 L.
