Yes, there will definitely be a time when we run out of fossil fuels to burn. It's often claimed that we have enough coal to last hundreds of years. But if we step up production to fill the gap left through depleting our oil and gas reserves, the coal deposits we know about will run out in 2088.

Answer:

Dark-colored mice are better able to hide from predators.

Explanation:

If all of the light mice are eaten, then there are none left to pass on the light-furred gene, meaning that there would be no offspring without dark fur.

25 points , hi! please look at the attachment for the question, I'm having a hard time because all I have to do is solve through

MAXImum [283]

Answer:

To answer the question, we correctly fill the attached screenshot as follows;

3H₂ + N₂ → 2NH₃
The molar mass of H₂ = 2 g/mol

$100.0 g \ H_2 \times \dfrac{1 \ mol \ H_2}{2 \ g \ H_2} \times \dfrac{2 \ mol \ NH_3}{3 \ mol \ H_2} = 33.\bar 3 \ mol \ NH_3$

The molar mass of N₂ = 28 g/mol

$100.0 g \ N_2 \times \dfrac{1 \ mol \ N_2}{28 \ g \ N_2} \times \dfrac{2 \ mol \ NH_3}{1 \ mol \ N_2} \approx 7.143 \ mol \ NH_3$

A. Therefore, the excess reactant is hydrogen gas H₂ because it makes the most amount of ammonia, NH₃ (33. $\bar 3$ moles of NH₃)

B. The limiting reactant in nitrogen, N₂, because it is the reactant that makes the least amount of the ammonia, NH₃ (approximately 7.143 mol NH₃)

C. The theoretical yield of ammonia, is the maximum amount of ammonium that can be produced from the reaction between the 100 g of hydrogen gas, H₂, and 100 g of nitrogen gas, N₂ which is given by the amount of ammonia produced by the limiting reactant which is approximately 7.143 mole of NH₃
