Answer:
restrict population growth ( second choice).
Answer:
An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor.
Explanation:
I believe that is condensation
There are different kinds of reactions. To name some, these are the synthesis reaction, decomposition reaction, single-replacement reaction, double-replacement reaction, combustion reaction, redox reaction, etc. For this type of reaction involving two reactants to yield only one product, <em>this is a synthesis reaction.</em>
<em>P₄ (s) + 6 Ca (s) --> 2 Ca₃P₂ (s)</em>
Answer:
- <em><u>The rate that SO₂ (g) reacts equals the rate that SO₃ (g) decomposes</u></em>.
Explanation:
The chemical equation for the reaction of sulfur dioxide and oxygen to produce sulfur trioxide is given:
- SO₂ (g) + O ₂ (g) ⇄ SO₃ (g)
The double arrow is indicating that this is an equilibrium reaction, which means that, once the reactants start to react, two reactions occur simultaneously:
- Direct or forward reaction:
SO₂ (g) + O ₂ (g) → SO₃ (g) . . . [the arrow goes from left to right]
SO₂ (g) + O ₂ (g) ← SO₃ (g) . . . [the arrow goes from right to left]
The chemical equilbrium is a dynamic equilibrium, which means that the species (reactants and products) do not remain static but they continue reacting: the rate of both direct and reverse reactions are equal, so in net terms the concentrations do not change.
A graph of reaction rate versus time shows the concentrations of reactants and products over time. Before reaching the equilibrium, the concentrations of reactants will decrease and the concentrations of products will increase, but when the equilibrium is reached the concentrations will remain constant, because, as explained the rate of both forward and reverse reactions are equal.
For the given equation, that means that SO₂ (g) (reactant in the forward reaction) will be consumed at the same rate that SO₃ (g) (reactant in the reverse reaction) will be decomposing.
