Not a timed or graded assignment. I’m in a time crunch so Quick answer = amazing review :)

Answer 1

`13.6\text{ g}`

Step-by-step explanation:

Here, we want to get the mass of zinc (ii) chloride to be produced

From the balanced equation of chemical reaction, we can see that:

1 mole of zinc produced 1 mole of zinc (ii) chloride

Now, let us get the number of moles of zinc that reacted actually

To get this, we have to divide the mass of zinc reacted by the atomic mass of zinc

The atomic mass of zinc is 65 amu

Thus, the number of moles of zinc that reacted will be:

`(6.5)/(65)\text{ = 0.1 mole}`

Since the number of moles of both is equal theoretically, it means that the number of moles of zinc (ii) chloride produced will be 0.1 mole too

To get the mass of zinc (ii) chloride produced, we have to multiply the number of moles produced by the molar mass of zinc (ii) chloride

The molar mass of zinc (ii) chloride is 136 g/mol

Thus, we have the mass, produced as:

`136\text{ }*\text{ 0.1 = 13.6 g}`
