Answer:Yes,enzymes are catalyzed reactions
Explanation:Enzymes are protein that speeds up chemical reactions. Enzyme catalyzed reaction are divided into two:
Homogeneous reaction
Heterogeneous reaction.
Homogeneous catalysts occupy the same phase as the reaction mixture, while heterogeneous catalysts occupy a different phase.
Acid catalysis, organometallic catalysis, and enzymatic catalysis are examples of homogeneous catalysis.
Vanadium oxide (V2 O5) is a brown/yellow solid on which the oxygen and sulfur dioxide can adsorb in order to react with each other to form sulfuric acid.
Chlorophyll, it is chlorophyll
B) Humus is the decayed organic material that gives soil its dark brown or black color.
Answer:
Benzene Hexachloride
Explanation:
BHC in benzene mean ''Benzene Hexachloride''.
<h2>B = Benzene</h2><h2>H + C = Hexachloride </h2>
As you can see, There are only two words and three letters. Even though it is one word, Hexa = H and Chloride = C
The number of atoms present in 0.231 g of sodium is 6.02 x 10²¹ atoms.
The given parameters;
- <em>mass of the reacting sodium = 0.231 g</em>
- <em>1 mole of an atom = 6.02 x 10²³ atoms</em>
- <em>the atomic mass of sodium is 23 g/mol</em>
The number of moles of 0.231 g of sodium available is calculated as;

The number of atoms of 0.01 mole of sodium available is calculated as;
1 mole ---------- 6.02 x 10²³ atoms
0.01 ----------------- ?
= 0.01 x 6.02 x 10²³ atoms
= 6.02 x 10²¹ atoms.
Thus, the number of atoms present in 0.231 g of sodium is 6.02 x 10²¹ atoms.
