tangare [24]3 years ago
6 0

1) The answer is: 2 moles of oxygen molecules.

Balanced chemical reaction of methane combustion:  

CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g).

Coefficients with the lowest ratio indicate the relative amounts of substances in a reaction.

In fronf of oxygen molecule is coefficient 2.

2) The answer is: 4 moles of oxygen atoms.

In one molecule of oxygen there are two oxygen atoms, so in two molecules there are four oxygen atoms.

How does Dr. Hayes' and Dr. Malaska’s research differ? Why are both research projects important?
kati45 [8]

Answer:

Answer:  What can experiments in a lab tell us about substances on Titan? Experiments in a lab can tell us that the lake did not evaporate in 2007 because the molecular attraction was a lot stronger, then it got weaker overtime.

How does Dr. Hayes' and Dr. Malaska’s research differ? Why are both research projects important? Their research differs because they were both talking about different things, Hayes was talking about how many lakes there were, while Malaska's was doing more hands on stuff like experiments. Both are important because we need to learn how the lakes formed, but we also need to do hands on experiments.

How many molecules of oxygen are needed to make 3.5 oxygens of water?​
max2010maxim [7]

Answer:

57.6g

Explanation:

So, if in one mole of water, 16 g of oxygen atom is present. Then, in 3.6 moles of water, the mass of oxygen present will be 3.6×16=57.6g. Therefore, the amount of oxygen present in 3.6 g water is option (B)- 57.6 g.
