How many moles of co2 will be produced from 72.0 g of ch4 assuming o2 is available in excess

Chemistry

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

arsen [322]

Answer:

a) ppm

b) ppm

c) ppb

d) ppt

e) ppb

Explanation:

a) You know that 1000 g are 1 kg, and 1000 kg are 1 ton, so (1000)*(1000) g are 1 ton, so 1,000,000 grams are one ton.

b) 1000 mg are 1 g, and 1000 g are 1 liter, so 1,000,000 grams are one liter.

c) You know that 1000 ug are 1 mg, so with the b), we just need to multiply the answer by 1000, so 1,000,000,000 ug are 1 liter.

d) The same as c, 1000 ng are 1 mg. So we are talkinf of ppt.

e) 1000 mg are 1 g. And 1000 g are 1 kg, then 1000 kg are one ton. So 1,000,000,000 mg are one ton.

Most atoms have no net charge because they have
Ne4ueva [31]

Atoms have no electric charge because the protons and electrons "cancel out" each others charges. Neutrons have no charge. What is the atomic number of an element? The atomic number is the number of protons in the atom's nucleus.

Hope this helps have a great day :)
