Answer: D. The temperature fluctuates

Explanation:

I will say this as a result of varying time of the day. Let me explain by comparing effects of day and night in cloud cover.

During the day:

As the cloud cover increases, the sun's heat (Ray) is repelled back to the cloud due to the covering present. Therefore, less of the sun's energy gets to the Earth's surface, this gives the earth a much cooler feeling and as a result the temperature is reduced.

During the night:

In this scenario, the opposite is the case as the cloud traps the heat which is supposed to be given off by the earth surface and re-emits it back towards the earth. This causes the Earth's temperature to become warmer, as a result increases the temperature.

According to this chemical reaction, which is the number of grams of Fe produced from 14 moles of H2? Fe3O4 + 4 H2 → 3 Fe + 4 H2
IRINA_888 [86]

Answer:

\boxed{\text{586 g}}

Explanation:

We know we will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.

M_r:                            55.85  

            Fe₃O₄ + 4H₂ → 3Fe + 4H₂O

n/mol:                  14

1. Use the molar ratio of Fe:H₂ to calculate the moles of Fe.

\text{Moles of Fe = 14 mol H$_{2}$}  \times \dfrac{\text{3 mol Fe}}{\text{4 mol H$_{2}$}} =\text{10.5 mol Fe}

2. Use the molar mass of Fe to calculate the mass of Fe

\text{Mass of Fe = 10.5 mol Fe} \times \dfrac{\text{55.85 g Fe}}{\text{1 mol Fe}} = \textbf{586 g Fe}\\\\\text{The reaction will produce $\boxed{\textbf{586 g}}$ of Fe}

How many moles are in 0.456 g of chlorine
Mila [183]

Answer:

0.013 moles Cl

Explanation:

Grams --> Moles       Divide by Molar Mass

Molar Mass of Chlorine (Cl) is 35.5. This can be found on the Periodic Table.

Set Up:     (0.456 g Cl) (1 Cl / 35.5 g)

                0.456 g * 1 = 0.456

                0.456 / 35.5 = 0.01284507

                Round to 0.013
