<span>Most living things on Earth are made of carbon.
Living things need carbon in order to live, grow, and reproduce.
Carbon is a finite resource that cycles through the Earth in many forms.
This makes carbon available to living organisms and remains in balance with other chemical reactions in the atmosphere and in bodies of water like ponds and oceans.</span>
Answer:
See the explanation below, please.
Explanation:
In redox reactions (oxide reduction) the transfer of electrons between compounds occurs.
In oxidation, electrons are lost (positive charge increases). Example:
Mg ---> Mg2 + + 2 e- (passes from Mg ° to Mg 2+)
On the other hand in the reduction, electrons are gained (negative charge increases or the positive one increases). Example:
Cl2 + 2e- ---> 2 Cl- + 2 e- (passes from Cl ° to Cl-)
The molecules go flying apart as they become a gas ( like a boiling liquid that ends making vapor.) This process is called evaporation.
Temperature and salinity changes the density of water.
<h3>Effect of Temperature and salinity on water</h3>
Temperature and salinity directly affect density of water. Water that low temperature is more denser than water that has high temperature while on the other hand, Freshwater which has no salt is less denser than seawater which has more salt concentration so we can conclude that temperature and salinity changes the density of water.

The pressure of the gas is obtained as 48 atm.
<h3>What is the total pressure?</h3>
Now we know that;
Number of moles of CH4 = 48.0 grams /16 g/mol = 3 moles
Number of moles of H2 = 56.0 grams/2 g/mol = 28 moles
Total number of moles present = 3 moles + 28 moles = 31 moles
Using;
PV =nRT
P = total pressure
V = total volume
n = total number of moles
R = gas constant
T = temperature
P = nRT/V
P = 31 * 0.082 * 286/15
P = 48 atm
