9. How many grams of zinc are needed to produce 12 grams of zinc chloride according to the following equation? Y-
tensa zangetsu [6.8K]

Given :

A balanced chemical equation :

Zn +Cl_2->ZnCl_2

To Find :

How many grams of zinc are needed to produce 12 grams of zinc chloride.

Solution :

Moles of ZnCl_2 ,

n=\dfrac{Given \ wt}{Molecular\ Mass}\\\\n =\dfrac{12}{136.30}\ mol\\\\n=0.088\ mol

Now, by balanced chemical equation we can say that 1 mol of Zn produce

1 mol of ZnCl_2 .

So, 0.088 mol of Zn is required to produced 0.088 mol of ZnCl_2 .

Mass \ required = molecular \ mass \times moles\\\\m = 65.38 \times 0.088\\\\m=5.8 \ gm

Therefore, 5.8 grams of zinc is required.

Hence, this is the required solution.

How many grams of NaOH are required to neutralize 700 mL of 3.0 M HCl?
sveta [45]

A gram of NaOH required to neutralize 700 ml HCL is <u>84 grams.</u>

Neutralization or neutralization is a chemical response in which an acid and a base react quantitatively with each different. I

Moles of solute = Molarity × Liters of solution

                           = 3 × 0.7 L

                          = 2.1 mole

The molar mass of NaOH = 40

mass of NaOH = 40 × 2.1 g

                        =<u> 84 gram.</u>

A neutralization response may be described as a chemical reaction in which an acid and base quantitatively react together to shape salt and water as products. In a neutralization response, there's a combination of H+ ions and OH– ions that form water.

A neutralization response is when an acid and a base react to shape water and salt and includes the mixture of H+ ions and OH- ions to generate water. The neutralization of a sturdy acid and robust base has a pH equal to 7.
