Moles of CO₂ produced will be 4.5

<u>Explanation:</u>

CH₄ + 2O₂ → CO₂ + 2H₂O

Molecular weight of CH₄, M = 16

given mass of CH₄, m = 72

moles of CH₄, n = given mass / molecular mass

n = \frac{m}{M} \\\\n = \frac{72}{16} \\\\n = 4.5

Therefore, number of moles of CH₄ present is 4.5

According to the balanced equation,

1 mole of CH₄ produces 1 mole of CO₂

4.5 moles of CH₄ will produce 4.5 moles of CO₂

Therefore, moles of CO₂ produced will be 4.5

You wash dishes for a chemistry laboratory to make extra money for laundry. You earn 12 dollars/hour, and each shift lasts 75 mi
PIT_PIT [208]
You calculate the amount of loads of laundry as follows:

((6 x 0.25)/ load) x 10 loads = 15.00 total cost required for laundry 

<span>(6.00 / 60 min) x (75 min/shift) = 7.50 cost / shift </span>

15.00 / (7.50 / shift) = 2 loads of  laundry

Hope this answers the question.

The following chemical reaction occurs in a basic solution.
Dafna1 [17]

Answer:

6 moles of electrons

Explanation:

Let us consider the species NO3− and ClO−. The NO3− is oxidized to NO the oxidation number of nitrogen is decreased from +5 to +2.

The oxidation number of chlorine is increased from +1 to +3. This implies that six electrons were transferred in the balanced reaction equation shown in the question. Hence the answer.
