If 0.400 moles CO and 0.400 moles O2 completely react, 17.604 grams of CO2 would be produced.
First, let us look at the balanced equation of reaction:

According to the equation, the mole ratio of CO and O2 is 2:1. But in reality, the mole ratio supplied is 1:1. Thus, CO is the limiting reactant while O2 is in excess.
Also from the equation, the ratio of CO consumed to that of CO2 produced is 1:1. Thus, 0.400 moles of CO2 would also be produced from 0.400 moles of CO.
Recall that: mole = mass/molar mass
Therefore, the mass in grams of CO2 that would be produced from 0.400 moles can be calculated as:
Mass = mole x molar mass
= 0.400 x 44.01
= 17.604 grams

Answer:
There are 23076 peanut M&M's in 53.768 kg of M&M's.
Explanation:
First we <u>convert 53.768 kg into g</u>:
- 53.768 kg * 1000 = 53768 g
Then we <u>divide the total mass of M&M's by the mass of one peanut M&M,</u> in order to calculate the answer:
So there are 23076 peanut M&M's in 53.768 kg of M&M's.
Answer:
3rd statment
Explanation:
ray 1 and 2 are same vertical line
The answer is 4.
Gases have low densities, because of the increased space between hight-energy particles.
The answer is mixture, hope this helps!
