More valence electrons and larger atomic radius are facts most suitable for increasing the electrical conductivity of metals.
Answer: The percentage composition of nitrogen , hydrogen and oxygen is 22.2 % , 1.59 % and 76.2% respectively.
Explanation:
Percentage composition is defined as the ratio of mass of substance to the total mass in terms of percentage.
Percentage composition=
a) 
b) 
c) 
The percentage composition of nitrogen , hydrogen and oxygen is 22.2 % , 1.59 % and 76.2% respectively.
Conservation of energy
all of it should be transformed since the energy is convserved (neither destroyed nor created)
so answer is B
Answer: enzymes.
Explanation:
Microbial products are products derived from microorganisms. They may be primary or secondary metabolites. They are known to be environment friendly since they have biological origin. They are often degraded by enzymes which are also biological molecules. Degradation of materials using enzymes typically generates nontoxic products.
Sodium hydroxide and bleach have several characteristics in common and that includes: both can conduct electricity in solution, both can be found in the cleaning products and they are able to produce hydroxide ions in solution. However, their pH are not less than 7. Sodium hydroxide has a pH of 13, while bleach has a pH of 11. Therefore, both of them has a pH greater than 7. So the characteristic that they don't have in common is letter A.
