Answer:
O The number of oxygen atoms in the reactants used by this process equals the total number of oxygen atoms in the products.
Explanation:
The statement that best describes how photosynthesis follows the law of conservation of mass is that the number of oxygen atoms in the reactants used by this process is equal to the total number of oxygen atoms in the products.
The equation of photosynthesis reaction is given as:
6CO₂ + 6H₂O → C₆ H₁₂ O₆ + 6O₂
According to the law of conservation of mass, matter is neither created nor destroyed during the course of a chemical reaction.
By the virtue of this, the number of oxygen atom on both sides of the expression must be the same. Also, the number of carbon and hydrogen atoms must also be the same.
Answer: The percent yield for the 
is, 86.7 %
Explanation : Given,
Moles of 
= 2.36 mol
Moles of = 6.14 mol
First we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 2 moles of react to give 6 moles of
So, 2.36 moles of react to give 
mole of
Now we have to calculate the percent yield for the .
Experimental yield = 6.14 moles
Theoretical yield = 7.08 moles
Now put all the given values in this formula, we get:
Therefore, the percent yield for the is, 86.7 %
The energy needed to remove an electron from an atom is called ionization energy.
Answer:
Explanation:
Convert the word equation to a chemical equation.
one atom magnesium + two atoms Cl form magnesium chloride
Mg + 2Cl ⟶ MgCl₂
