Zinc reacts with hydrochloric acid according to the following equation:

Zn + 2HCl --> ZnCl2 + H2

If 3.63 grams of zinc react, how many grams of zinc chloride is produced?

Convert 3.63 g Zn to mols. mols = grams/molar mass.

Use the equation coefficients to convert mols Zn to mols ZnCl2.
Convert mols ZnCl2 to g. g = mols x molar mass.

To find the grams of zinc chloride produced, we need to determine the stoichiometric ratio between zinc and zinc chloride. Looking at the balanced chemical equation:

Zn + 2HCl -> ZnCl2 + H2

We see that one mole of zinc reacts to produce one mole of zinc chloride. The molar mass of zinc (Zn) is 65.38 g/mol, and the molar mass of zinc chloride (ZnCl2) is 136.29 g/mol.

First, calculate the number of moles of zinc (Zn):

moles of Zn = mass of Zn / molar mass of Zn
moles of Zn = 3.63 g / 65.38 g/mol
moles of Zn = 0.0556 mol

Since the stoichiometric ratio is 1:1 between zinc and zinc chloride, we can conclude that the same number of moles of zinc chloride is produced.

Next, calculate the grams of zinc chloride (ZnCl2):

grams of ZnCl2 = moles of ZnCl2 * molar mass of ZnCl2
grams of ZnCl2 = 0.0556 mol * 136.29 g/mol
grams of ZnCl2 = 7.56 g

Therefore, 3.63 grams of zinc would produce 7.56 grams of zinc chloride.

To find the number of grams of zinc chloride produced, we need to use stoichiometry and the given mass of zinc.

First, we need to determine the molar mass of zinc (Zn) and zinc chloride (ZnCl2). The molar mass of an element or compound is the sum of the atomic masses of its constituent atoms.

The molar mass of zinc (Zn) is 65.38 g/mol (the atomic mass of zinc is 65.38 g/mol).

The molar mass of zinc chloride (ZnCl2) is 136.29 g/mol. This is calculated by adding the atomic masses of zinc (65.38 g/mol) and chlorine (Cl) (35.45 g/mol) together. Since there are two chlorine atoms in zinc chloride, we multiply the atomic mass of chlorine by 2.

Next, we can set up a ratio using the coefficients from the balanced chemical equation:

1 mole of zinc (Zn) reacts to produce 1 mole of zinc chloride (ZnCl2).

Using the molar mass of zinc (Zn), we can convert the given mass of zinc to moles. The conversion factor is:

1 mole Zn / 65.38 g Zn

Calculating the number of moles of zinc reacted:

(3.63 g Zn) * (1 mole Zn / 65.38 g Zn) = 0.05549 moles Zn (rounded to 5 decimal places)

Since the mole ratio between zinc (Zn) and zinc chloride (ZnCl2) is 1:1, the number of moles of zinc chloride produced is also 0.05549 moles.

Finally, we can convert the number of moles of zinc chloride to grams using its molar mass:

0.05549 moles ZnCl2 * 136.29 g ZnCl2 / 1 mole ZnCl2 = 7.56 grams ZnCl2 (rounded to 2 decimal places).

Therefore, 3.63 grams of zinc will react to produce 7.56 grams of zinc chloride.
