Alexandra [31]

(a) 43.6 mg; (b) 520 mg

(a) Mass of phosphoric acid (PA) in a dose

Mass of PA = 2 tsp × (21.8 mg PA/1 tsp) = 43.6 mg PA

(b) Mass of PA in the bottle

Step 1. Convert ounces to millilitres

Volume = 4 oz × (30 mL/1 oz) = 120 mL

Step 2. Calculate the mass of PA

Mass of PA = 120 mL × (21.8 mg PA/5 mL) ≈ 520 mg PA

How many grams of LiOH are produced from 9.89 g of Li?

Nonamiya [84]

Taking into account the stoichiometry of the reaction, 34.12 grams of LiOH are produced from 9.89 g of Li.

In first place, the balanced reaction is:

2 Li + 2 H₂O ⇒ 2 LiOH + H₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Li= 2 moles
H₂O= 2 moles
LiOH= 2 moles
H₂= 1 mole

The molar mass of each compound is:

Li= 6.94 g/mole
H₂O= 18 g/mole
LiOH= 23.94 g/mole
H₂= 2 g/mole

By reaction stoichiometry, the following amounts of mass of each compound participate in the reaction:

Li= 2 moles× 6.94 g/mole= 13.88 g
H₂O= 2 moles× 18 g/mole= 36 g
LiOH= 2 moles× 23.94 g/mole= 47.88 g
H₂= 1 mole× 2 g/mole= 2 g

Then you can apply the following rule of three: if by reaction stoichiometry 13.88 g of Li produce 47.88 g of LiOH, 9.89 g of Li produce how much mass of LiOH?

$mass of LiOH=\frac{9.89 g of Li*47.88 g of LiOH}{13.88 f of Li}$

Solving:

mass of LiOH= 34.12 grams

Finalli, 34.12 grams of LiOH are produced from 9.89 g of Li.

Write a balanced chemical equation for this reaction. What is the coefficient for hydrochloric acid in the reaction

Leviafan [203]

The question is incomplete, here is the complete question:

Write a balanced equation for the neutralization of calcium hydroxide by hydrochloric acid. What is the coefficient for hydrochloric acid in the reaction.

Answer: The balanced chemical reaction is written below and the coefficient of hydrochloric acid is 2.

Explanation:

Neutralization reaction is defined as the reaction in which an acid reacts with a base to produce a salt and water molecule.

Balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side will be equal to the total number of individual atoms on the product side. These equations follow law of conservation of mass.

The balanced chemical equation for the reaction of calcium hydroxide and hydrochloric acid follows:

$Ca(OH)_2+2HCl\rightarrow CaCl_2+2H_2O$

By Stoichiometry of the reaction:

1 mole of calcium hydroxide reacts with 2 moles of hydrochloric acid to produce 1 mole of calcium chloride and 2 moles of water molecule.

Hence, the balanced chemical reaction is written below and the coefficient of hydrochloric acid is 2.
