The characteristics of enzymes that give them this effectiveness as catalysts are they are made up of protein, they do not consume in the reaction ad lower the activation energy.
<h3>What is an enzyme?</h3>
The enzyme is a biological catalyst. The substrate is bound to them, and they supply the activation energy. It is the quantity of energy needed to initiate the reaction.
They are effective catalysts, as a small amount of them can affect a large amount of reaction.
Thus, enzymes are made of protein, do not consume in the reaction, and have reduced activation energy, which contributes to their efficiency as catalysts.

molar concentration of AgNO₃ solution = 0.118 mole/L
Explanation:
Because we have the volume of the solution and there is no information about the density of the solution I will asume that you ask for the molar concentration.
number of moles = mass / molecular weight
number of moles of AgNO₃ = 10 / 170 = 0.0588
molar concentration = number of moles / volume (L)
molar concentration of AgNO₃ solution = 0.0588 / 0.5
molar concentration of AgNO₃ solution = 0.118 mole/L

Answer:
Ca.
Sb.
Explanation:
a. When comparing the two elements Ca and As , the more metallic element is:__________ based on periodic trends alone.
The correct option is Ca. Ca belongs to group 2 which is more easily give off it's electrons, compared to As which is a group 5 member.
c. When comparing the two elements Sb and Pb , the more metallic element is:___________ based on periodic trends alone.
The correct option here is Pb. Thhs is because ionization energy decreases down the group. Pb has a lower ionization enthalpy than Sb
Answer: 10% (v/v).
Explanation:
V - unit is litre
m/m - by mass concentration
m/v - unit of density
v/v - concentration by volume
