Answer:

2H₂ + O₂ → 2H₂O

Explanation:

Chemical equation:

H₂ + O₂ → H₂O

Balance chemical equation:

2H₂ + O₂ → 2H₂O

Step 1:

H₂ + O₂ → H₂O

Left hand side Right hand side

H = 2 H = 2

O = 2 O = 1

Step 2:

H₂ + O₂ → 2H₂O

Left hand side Right hand side

H = 2 H = 4

O = 2 O = 2

Step 3:

2H₂ + O₂ → 2H₂O

Left hand side Right hand side

H = 4 H = 4

O = 2 O = 2

What is the molarity of a solution that contains 0.400 mol HCl in 9.79 l solution?

Maslowich

Answer:

Option B, 0.0409 M

Explanation:

1) Data:

a) M = ?

b) n = 0.400 mol

V = 9.79 liters

2) Formula:

M = n / V (in liters)

3) Solution:

M = 0.400 mol / 9.79 liter = 0.04086 M

Since each data contain 3 significant digits, the answer must be reported with 3 significant digits. So, the correct answer is 0.0409 M, which is the option B.
