The correct description of the role that enzymes play in biochemical reactions would be B. Enzymes bond with one or more reactants and lower the activation energy needed for the reaction.
primarily ionic include = sodium iodide( NaI) , calcium chloride ( CaCl2)
primarily covalent include - Ammonia (NH3) , Methane ( CH4) and
Glucose (C6H12O6)
Explanation
ionic bond is formed when there is complete transfer of electron between atoms. It occur between metal which donate electrons and a non metal which accept electrons.
for example in formation of CaCl2, ca donate 2 electron to 2 Cl atom, while 2 Cl atom accept the 2 electrons to form ionic bond.
Covalent bond is formed when two or more non metal form bond by sharing electrons pairs.
For example in NH3 3 pairs of electron are shared. to form covalent bond.
Answer:
1500 cubic centimeters or cm^3
Explanation:
1 liter is 1000 cm^3
move the decimal 3 places to right
It might be energy or batteries I'm not saying it's right but I might be wrong
