Answer:
This is true.
Explanation:
The sun is the star we orbit so in order for there to be night and day we would have to spin.
Answer:
Aldehydes derive their name from the dehydration of alcohols. Aldehydes contain the carbonyl group bonded to at least one hydrogen atom. Ketones contain the carbonyl group bonded to two carbon atoms. Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O

Answer: B(water)
Explanation:
Photosystem II uses energy from light to extract electron from water molecule to fill the hole left as the energized electron passes up the chain.When the electrons are removed from the water molecules,the water molecule breaks down into oxygen gas,which bubbles away, and hydrogen ions,which are used to power ATP synthesis.
Answer : The molarity of the new solution is, 4.069 M
Solution : Given,
Molarity of KOH solution = 4 M
Volume of KOH solution = 2.5 L
Volume of water added = 1.8 L
First we have to calculate the volume of new solution.
Volume of new solution = volume of KOH solution + volume of water added
Volume of new solution = 2.5 L + 1.8 L = 4.3 L
Now we have to calculate the molarity of the new solution.
Formula used :
where,
= molarity of KOH solution
= molarity of new solution
= volume of KOH solution
= volume of new solution
Now put all the given values in the above formula, we get the molarity of the new solution.
Therefore, the molarity of the new solution is, 4.069 M
Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45. What is the activation energy for this reaction is described below.
Explanation:
When the rates are equal and the concentration of reactants and products are constant not equal. Other like activation energies and potential energies are not necessary for equilibrium.
The activation energies of the forward and reverse reactions ,the rates of the forward and reverse reactions are 25 minutes ago.
For a hypothetical reaction the linear Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45
15kj/mol is the answer..
