In the equation CH4 + 2O2 --> 2H2O + CO2 What is the mass of CO2 produced when 35g of O2 reacts?
Answer:
24.06 g of CO₂
Explanation:
The balanced equation for the reaction is given below:
CH₄ + 2O₂ —> 2H₂O + CO₂
Next, we shall determine the mass of O₂ that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:
Molar mass of O₂ = 2 × 16 = 32 g/mol
Mass of O₂ from the balanced equation = 2 × 32 = 64 g
Molar mass of CO₂ = 12 + (2×16)
= 12 + 32
= 44 g/mol
Mass of CO₂ from the balanced equation = 1 × 44 = 44 g
SUMMARY:
From the balanced equation above,
64 g of O₂ reacted to produce 44 g of CO₂.
Finally, we shall determine the mass of CO₂ produced by the reaction of 35 g of O₂. This can be obtained as follow:
From the balanced equation above,
64 g of O₂ reacted to produce 44 g of CO₂.
Therefore, 35 g of O₂ will react to produce = (35 × 44)/64 = 24.06 g of CO₂.
Thus, 24.06 g of CO₂ were produced from the reaction.
Give examples of kinetic energy and how they work.
Answer: The kinetic energy of an object depends on both its mass and velocity, with its velocity playing a much greater role. Examples of Kinetic Energy: ... A baseball thrown by a pitcher, although having a small mass, can have a large amount of kinetic energy due to its fast velocity.

is pH 6 a weak or strong acid?
Answer:
6 pH is a weak acid
Explanation:
Generally, a strong acid has a pH of about zero to 3.
The pH scale typically ranges from 1 to 14, with lower numbers representing acids, higher numbers, bases. Neutral liquids like water have a pH of 7.

How many moles of nitrogen (N2) are needed to produce 9.60x10^24 molecules
of nitrogen dioxide (NO2)? *
The number of moles of Nitrogen : == 7.975
Further explanationGiven
9.60x10²⁴ molecules of nitrogen dioxide (NO2)
Required
The number of moles
Solution
Reaction
N2 + 2O2 → 2NO2
moles of NO2 :
= 9.6 x 10²⁴ : 6.02 x 10²³
= 15.95
From the equation, mol N2 :
= 1/2 x mol NO2
= 1/2 x 15.95
= 7.975
The number of molecules :
= 8 x 6.02 x 10²³
= 4.816 x 10²⁴
