Answer:
Enzymes are homogenous, thermolabile,biological catalyst that increases the reaction rate of a chemical reaction.
Explanation:
Enzymes are used as catalyst in many biochemical reactions.Enzymes basically interact in a complementary fashion with the transition state of the reaction thus helping to decrease the energy barrier called activation energy.Thus enzymes helps to stimulate the velocity of biochemical reaction.
It is very important point to note that enzymes do not affect the reaction equilibrium.
Answer:
B. NO₂, nitrogen dioxide
Explanation:
Nitrogen dioxide is one of the oxides of nitrogen. It reacts highly and is very harmful for the health of humans. It is regarded as one of the pollutants of the air pollution. The chemical formula of Nitrogen dioxide is NO₂. This gas is produced during the manufacturing of the fertilizers in the industries. Burning of the fossil fuels also contribute in the emission of nitrogen dioxide. Two atoms of oxygen when reacts with one atom of Nitrogen, Nitrogen dioxide is formed.
Answer:
halogens
Explanation:
Electronegativity increases as you move to the right and up the periodic table. Thus, halogens would have the greatest electronegativity.
