Zn + 2 HCl ZnCl2 + H2
son4ous [18]

Answer:

0.153 moles of hydrogen.

B) Multiply 10 grams of Zn x (1 mol Zn/65.39 g)

Explanation:

Given data:

Mass of zinc = 10 g

Moles of hydrogen = ?

Solution:

Chemical equation:

Zn + 2HCl  →  ZnCl₂ +  H₂

Number of moles of zinc:

Number of moles of zinc = mass/ molar mass

Number of moles of zinc = 10 g/ 65.4 g/mol

Number of moles of zinc = 0.153 mol

Now we will multiply the moles of Zn with hydrogen:

                     Zn            :            H₂

                      1              :              1

                     0.153       :            0.153

A box has dimensions of 2.0 cm time 4.0 cm times 8.0 cm, what is the volume of the box in milliliters?
larisa86 [58]

Answer:

64 mL.

Explanation:

From the question given above, the dimension of box is:

Dimension = 2 cm × 4 cm × 8 cm

Thus, the volume of the box is:

Volume = 2 cm × 4 cm × 8 cm

Volume = 64 cm³

Finally, we shall convert 64 cm³ to mL. This can be obtained as follow:

Recall:

1 cm³ = 1 mL

Therefore,

64 cm³ = 64 cm³ × 1 mL / 1 cm³

64 cm³ = 64 mL

Therefore, the volume of the box in millilitres (mL) is 64 mL.
