Answer:

<em>The calculation of quantities is chemical equations is called </em><u><em>stoichiometry.</em></u>

Explanation:

In a chemical reaction, as a result of the law of conservation of mass, reactants combine in fixed proportions to form the products.

Then, a chemical reaction is characterized by cuantitative relations between the atoms and compounds, which permit to make predictions on how much product can be obtained from certain amounts of reactants or how much of each reactant you would need to obtain a desired amount of product.

<em>Stoichiometry</em> is the use of the mole coefficients of a chemical equation to state ratios and set proportions, and, so, determine the number of moles or masses of reactants and products.

What would happen if N2 were added to N2(g) + O2(g) = 2NO(9) at

DerKrebs [107]

Balanced chemical equation is :

$N_2(g)+O_2(g)-->2NO(g)$

It is given that the equation is in equilibrium.

We need to find what will happen if we add more $N_2$ is added .

By Le Chatelier's principle :

Changing the concentration of a chemical will shift the equilibrium to the side that would counter that change in concentration.

It means production of the side where content is added will decrease and concentration on other side will increase .

So , more NO would form .

Therefore, option B. is correct.

Hence, this is the required solution.

THURSDAY Mr. Pate's science class performed an experiment involving the chemical reaction of sodium bicarbonate (baking soda) an

Kitty [74]

The balloon will burst if the volume of the balloon is less than 1.68 L since 8 g of sodium bicarbonate produces 1.68 L of carbon dioxide gas.

<h3>What is the volume of carbin dioxude produced from the chemical reaction between sodium bicarbonate (baking soda) and vinegar?</h3>

The volume of carbon dioxide produced is obtained from the equation below:

$CH_3COOH + NaCO_3 \rightarrow CH_3COONa + H_2O + CO_2 \\$

1 mole of sodium bicarbonate reacts with one mole of acetic acid in vinegar to produce 1 mole of carbon dioxide.

The volume of 1 mole of carbon dioxide is 22.4 L

Moles of sodium bicarbonate in 8 g = mass/molar mass

molar mass of sodium bicarbonate = 106 g

moles of sodium bicarbonate = 8/106 = 0.075 moles

Moles of carbon dioxide produced = 0.075 moles

Volume of carbon dioxide = 0.075 × 22.4 = 1.68 L

Therefore, the balloon will burst if the volume of the balloon is less than 1.68 L.
