Answer:
44 grams of CO₂ will be formed.
Explanation:
The balanced reaction is:
C + O₂ → CO₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:
- C: 1 mole
- O₂: 1 mole
- CO₂: 1 mole
Being the molar mass of each compound:
- C: 12 g/mole
- O₂: 32 g/mole
- CO₂: 44 g/mole
By stoichiometry the following mass quantities participate in the reaction:
- C: 1 mole* 12 g/mole= 12 g
- O₂: 1 mole* 32 g/mole= 32 g
- CO₂: 1 mole* 44 g/mole= 44 g
The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
If 12 grams of C react, by stoichiometry 32 grams of O₂ react. But you have 40 grams of O₂. Since more mass of O₂ is available than is necessary to react with 12 grams of C, carbon C is the limiting reagent.
Then by stoichiometry of the reaction, you can see that 12 grams of C form 44 grams of CO₂.
<u><em>44 grams of CO₂ will be formed.</em></u>
If the population of frogs decreased, an animal that eats frogs and trout will decrease because it's food source is declining. Then, since the predator population is declining, the trout population will increase. The trout will have less predators to worry about.

My educated guess should be the 3rd one
Answer:
1.332 meters per second. // 2.664 meters per second.
Explanation:
the slower person moved 33.3 meters, and the faster person moved 66.6 meters.
the slower person is moving 33.3 meters in 25 seconds, while the other person is moving 66.6 meters in 25 seconds
slower person moved 33.3/25 = 1.332 meters per second.
faster person moved 66.6/25 = 2.664 meters per second.
