Answer:
True.
Explanation:
An exothermic reaction has a positive enthalpy (heat) of reaction. However, it can be negative in some circumstances.
The boiling point of the fluid depends on the intermolecular forces between the fluid atoms and molécules, as these forces must be disrupted to switch from a fluid to a gas. The stronger the intermolecular forces, the greater the point of boiling.
N=14
H= 1(5)= 5
C=12(2)=24
O=16(2)=32
= 75
The correct answer is B. Low chemical reactivity
Answer:
Basicity is measured on a scale called the pH scale. On this scale, a pH value of 7 is neutral, and a pH value of more than 7 to 14 shows increasing basicity.
pH value of 7 is weak base and value of 14 means strong base.
