B.
its the only one with ozone in the reaction O₃
The number of sandwiches that can made with 6 pieces of bread and 4 slices of cheese is 3 sandwiches.
<h3>What are limiting reactants?</h3>
Limiting reactants are those reactants which determine the amount of product that can be formed since they get used up in a reaction.
In the making of sandwiches from bread and cheese, the limiting reactant is the material that is used up.
The formula for making a sandwich is given below;
2 pieces of bread + 1 slice of cheese = 1 sandwich
6 pieces of bread can make 3 sandwiches
4 slices of cheese can make 4 sandwiches
Thus, bread is the limiting reactant.
Therefore, the number of sandwiches that can made with 6 pieces of bread and 4 slices of cheese is 3 sandwiches.

Answer:
72g of H2O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
2H2 + O2 —>2H2O
Next, we'll determine the mass of O2 that reacted and the mass of H2O produced from the balanced equation.
This is illustrated below:
Molar Mass of O2 = 16x2 = 32g/mol
Molar Mass of H2O = (2x1) + 16 = 18g/mol
Mass of H2O from the balanced equation = 2 x 18 = 36g
Summary:
From the balanced equation above,
32g of O2 reacted to produce 36g of H2O.
Now, we can obtain the mass of H2O produced when 64g of O2 react as follow:
From the balanced equation above,
32g of O2 reacted to produce 36g of H2O.
Therefore, 64g of O2 will react to produce = (64 x 36)/32 = 72g of H2O.
From the calculations made above, 72g of H2O is produced from the reaction.
