Answer:
It is greater than the mass of oxygen formed.
Explanation:
<em>Photosynthesis</em> is the process of using light energy to convert carbon dioxide and water to glucose and oxygen.
6CO₂ + 6H₂O ⟶ C₆H₁₂O₆ + 6O₂
Mass of CO₂ + H₂O = mass of C₆H₁₂O₆ + 6O₂
Subtract the mass of glucose from the right-hand side but not the left. Then
Mass of CO₂ + H₂O > mass of O₂
A is <em>wrong</em>, because glucose is <em>formed</em>, not used.
Bb is <em>wrong</em>, because oxygen is <em>formed</em>, not used.
C is <em>wrong</em>, because the total mass of reactants is <em>greater than</em> just one of the products.
I believe the answer is B, or option 2. It makes the most sense, and is a fact.
Assuming that the reaction is the following:
A -> B
<-
The k expression would be written as the concentration or amount of product divided by the amount of reactant. In the case, where the quantity of B is much larger than A would result in a very small K value, which in this case would be D. 6 X 10^-7.
Answer: -
Magnesium reacts very slowly to form magnesium hydroxide and hydrogen gas. The balanced chemical equation for the reaction is
Mg + 2H₂O → Mg(OH)₂ + H₂
Explanation: -
Chemical symbol of magnesium = Mg
Chemical formula for magnesium hydroxide = Mg(OH)₂
Chemical formula for hydrogen gas = H₂
The other reactant with Mg must be water H₂O.
Thus the balanced chemical equation for the reaction is
Mg + 2H₂O → Mg(OH)₂ + H₂
