If 148.8 grams HCl reacts with excess Zn, how many moles of ZnCl2 could be formed? (Molar mass of HCI=36.46 g/mol)

2.04moles

Explanation:

The balanced chemical equation of this reaction is given as follows:

Zn + 2HCl → ZnCl2 + H2

Based on the above balanced equation, 2 moles of hydrochloric acid (HCl) reacts to produce 1 mole of Zinc chloride (ZnCl2).

The question states that 148.8 grams HCl reacts. We need to convert this value to mole by using the formula;

mole = mass/molar mass

Molar mass = 36.46g/lol

mole = 148.8/36.46

mole = 4.08moles of HCl

Hence, if 2 moles of hydrochloric acid (HCl) reacts to produce 1 mole of Zinc chloride (ZnCl2).

Then, 4.08moles of HCl will react to produce (4.08 × 1/2)

= 2.04moles of ZnCl2.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
