That's false. Animals have mitochondria too. It's responsible for cellular respiration, not photosynthesis.
Answer:
In the presence of UV light, ethane will react with bromine in a substitution reaction. UV light is the condition under which the reaction will occur so it is written above the arrow in the chemical equation. As the reaction proceeds, the intensity of the re-brown colour of the bromine water decreases.
I believe it’s D
There is good and bad bacteria that can be both harmful and good for humans
Answer:

Explanation:
Hello.
In this case, given the described reaction, the formation of nitric acid turns out:

Since two hydrogen atoms are present at the reactants we balance it as follows:

In such a way, since there is a 1:2 mole ratio between water and nitric acid, the produced moles of nitric acid, turns out:

Best regards!
0.1033 moles of oxygen is needed to completely react with 9.5 G of Na.
