<h2>Answer:</h2>

The correct answer is the D which 2,1,2,1.

<h3>Explanation:</h3>
  • In a balanced chemical equation, the number of particular atom on the right side of the equation is equal to the number of that atom on the left side of the equation.
  • As in the left side of the equation, there are 2 F atom and 1 Br. While on the right side there are 1 F and 2 Br. S for the balancing, we will put coefficient to the equation.
  • And the equation will be:

2NaBr + CaF2 → 2NaF + CaBr2

D.
2NaBr + CaF2 --> 2NaF + CaBr2 gives you:

2Na                        2Na
2Br                         2F
1Ca                         1Ca
2F                           2Br

This is balanced.

Toy balloons are filled with hydrogen gas, at standard temperature, from a 10.0-liter cylinder. the initial pressure of the gas
madam [21]
To answer this item, we are to assume that the given gas behaves ideally such that it can follow one of the simplified ideal gas law as written below,

                  P₁V₁ = P₂V₂

where P is the pressure and V is the volume. 

Substituting the known values, while V₂ is unknown,

                 (100 atm)(10 L) = (1 atm)(V₂)

The value of V₂ is calculated to be equal to 1000 L. 

The number of balloons that can be filled is as calculated.
                      n = (1000 L) / (1 L / balloon)
                               n = 1000
