S + 2e⁻ → S²⁻ (sulfur will gain electrons)
Mg - 2e⁻ → Mg²⁺ (magnesium will lose electrons)
Magnesium is a metal which tends to give electrons which are received by the sulfur, which is a nonmetal and tends to gain electrons.
Answer: Option (A) is the correct answer.
Explanation:
Chemical equation for the given reaction is as follows.
And, the expression to calculate pH of this reaction is as follows.
pH = ![pk_{a} + log \frac{[HCOO^{-}]}{[HCOOH]}](https://tex.z-dn.net/?f=pk_%7Ba%7D%20%2B%20log%20%5Cfrac%7B%5BHCOO%5E%7B-%7D%5D%7D%7B%5BHCOOH%5D%7D)
As the concentration of 
is directly proportional to pH. Hence, when there occurs a decrease in the pH of the solution the ![[HCOO^{-}]](https://tex.z-dn.net/?f=%5BHCOO%5E%7B-%7D%5D)
will also decrease.
Thus, we can conclude that the statement, HCOO will accept a proton from HCl to produce more HCOOH and 
, best supports the student's claim.
Answer:
Photosynthesis
Explanation:
As the plants are converting the CO2 into O2... So the photosynthesis reduce the amount of CO2...
Saturated solution refer to a solution in which the dissolved solute is in equilibrium with the undissolved solute.
<h3>What is a saturated solution?</h3>
A saturated solution is a chemical solution that contain maximum amount of a solute which is dissolved in the solvent. The addition of anotheg solute will not dissolve in a saturated solution. The amount of solute that can be dissolved in a solvent to form a saturated solution depends on a variety of factors.
Therefore, Saturated solution refer to a solution in which the dissolved solute is in equilibrium with the undissolved solute
