Ice and water are both H2O. Ice has less energy so it is frozen. Water has more energy than ice. They are made up of the same molecules do yes, water and ice have the same composition. Hope this helps! ;)

Yes, because the water and ice are made out of the same thing - one is just frozen

Sulfuric acid was once produced through the reaction of sulfur trioxide with water. Sulfur trioxide can form through the reactio

vekshin1

Answer 1) In the given reaction of sulfuric acid

$2NO_{(g)} + O_{2}_{(g)} ----> 2NO_{2}_{(g)}$

$2NO_{2}_{(g)} + 2SO_{2}_{(g)} ----> 2NO}_{(g)} + 2SO_{3}_{(g)}$

On addition of nitrogen monoxide gas the reaction rate increases and more amount of product is formed.

So, it is clear that NO is the catalyst in this reaction.

Answer 2) This can be proven that NO is catalyst because it increases the rate of the reaction, but it is not consumed during the reaction, and it also gets regenerated at the end of reaction.

Hence, nitrogen mono oxide is considered as the catalyst in the given reaction.

Answer 3) It increases the rate of reaction by decreasing the activation energy of the reaction. Also it can be clearly seen in this reaction the NO is reacting with oxygen to lower the energy of activation. So, it is providing an alternative pathway for proceeding the reaction. This all confirms the assumptions of NO being the catalyst.

$2NO_{(g)} + O_{2}_{(g)} ----> 2NO_{2}_{(g)}$

WILL GIVE BRAINLIEST Which effect is one likely result of a forest fire? a. extinction b. adaptation c. speciation d. forced mig

MAVERICK [17]

Answer:

d. forced migration

Explanation:

Certain hazardous occurrences affect living organisms in their natural habitat. One of those occurrences is forest fire. Forest fire or vegetation fire is an uncontrollable break out of fire in a vegetation, affecting the inhabitants of the area.

The occurrence of a forest fire will lead to a forced migration of organisms from their natural habitat. Animals and other mobile organisms will be forced to leave behind their devastating habitat and migrate to a less threatened area in order to survive.
