Answer:
3 x 10²⁴ molecules
Explanation:
A mole is just a name that we use to substitute a number, just like a dozen means 12, a mole means 6.022 x 10²³. This gives us the unit conversion of 6.022 x 10²³ molecules SO₂/1 mol SO₂.
Round to the lowest number of significant figures to get 3 x 10²⁴ molecules SO₂

Answer:
101.56 of H₂O
Explanation:
The balanced equation for the reaction is given below:
CH₄ + 2O₂ —> CO₂ + 2H₂O
Next, we shall determine the mass of CH₄ that reacted and the mass of H₂O produced from the balanced equation. This is illustrated below:
Molar mass of CH₄ = 12 + (4×1.01)
= 12 + 4.04
= 16.04 g/mol
Mass of CH₄ from the balanced equation = 1 × 16.04 = 16.04 g
Molar mass of H₂O = (2×1.01) + 16
= 2.02 + 16
= 18.02 g/mol
Mass of H₂O from the balanced equation = 2 × 18.02 = 36.04g
SUMMARY:
From the balanced equation above,
16.04 g of CH₄ reacted to produce 36.04 g of H₂O.
Finally, we shall determine the mass of water, H₂O produced by the reaction of 45.2 g of methane, CH₄. This can be obtained as illustrated below:
From the balanced equation above,
16.04 g of CH₄ reacted to produce 36.04 g of H₂O.
Therefore 45.2 g of CH₄ will react to produce = (45.2 × 36.04)/16.04 = 101.56 g of H₂O.
Thus, 101.56 of H₂O were obtained.
Answer:
ok this is going to be a bit much but i will teach the basics. also this is an exothermic reaction
Explanation:
- concentration H2 increases: it shifts to the right. this decreases O2 and increase H2O and K stays the same
- concentration H2 decreases: it shifts to the left, it increases O2 and decreases H2O and K stays the same
- concentration of O2 increases: it shifts to the right, this decreases H2 and increase H2O and K remains the same
- concentration of O2 decreases: it shifts to the left. this increases H2 and decreases H2O and K stays the same
- concentration of H2O increases: it shifts to the left, this increases H2 and O2
- concentration of H2O decreases: it shifts to the right, this decreases H2 and O2
- temp. increase: shifts left, increase H2 and O2, decreases H20 and K decreases
- temp decrease: shifts right, decrease H2 and O2, increase H2O and K increases
- pressure increase: shifts right, decrease H2 and O2, increase H2O and K remains the same
ps i hope this helps. and i hope it isn't to confusing.

The moles of oxygen gas (O2) that is needed is 4 moles
Explanation
2H2 +O2 → 2H2O
The moles of O2 is determined using the mole ratio of H2:O2
that is from equation above H2:O2 is 2:1
If the moles of H2 is 8 moles therefore the moles of O2
= 8 moles x 1/2 = 4 moles
