Answer:

Explanation:
Hello!
In this case, since the enthalpy change for any process is computed by subtracting the enthalpy of the final state and the enthalpy of the initial state, for the given phase change, we subtract the enthalpy of the liquid (final state) and the enthalpy of the solid (initial state) considering this a melting process:

Which makes sense because this process absorbs energy.
Best regards!
Answer:
5.62 g of F2
Explanation:
We have to start with the chemical reaction:

<u>We have a balanced reaction</u>, so we can continue with the <u>mol calculation</u>. For this, we need to know the <u>molar mass</u> of
(70.906 g/mol), so:

Now, with the <u>molar ratio</u> between
and
we can convert from moles of
and
(1:3), so:

Finally, with the <u>molar mass</u> of
we can calculate the gram of
(37.99 g/mol), so:

I hope it helps!
Answer: Natural gas has a faster rate because, being a carbon resource, it quickly replenishes as part of the carbon cycle.
Explanation:
Natural gas is a natural gas which consists of mixtures of hydrocarbons. It is primarily composed of methane, alkanes, small percentage of nitrogen, hydrogen sulfide, helium and carbon dioxide.
Being a carbon source it can be replenished easily due to decomposition of organic matter generated after the decomposition of dead animal and plant matter.
The geothermal energy can be define as the energy obtained from the hot springs it includes the water that includes the thermal energy generate through heat present in the geosphere.
Although the geothermal energy is the renewable source of energy but the time and period of it's generation remains unknown from the hot spring. Therefore, the rate of renewal of energy of natural gas is faster than the geothermal energy.
Because they heavier it is the slower it will go
