Answer
is: concentration of hydrogen cations in lemon juice is 4.00 × 10−3 m.
pH
= 2.4.
pH
= -log[H₃O+].
[H₃O+] = 10∧(-pH).
[H₃O+] = 10∧(-2.4).
[H₃O+] = 0.004 mol/L.
pH value (potential of hydrogen - [H+]) is a logarithmic scale that
specify the acidity or basicity of an aqueous solution. When pH is greater than
seven, aqueous solution is basic, below seven is acidic and when pH is equal
seven, solution is neutral.

TRUE.
Nonmetals have some similar physical properties.
En general:
- They are either gases or brittle solids.
- They are opaque
- They are poor conductors of heat and electricity.
Answer:
No, because the amount of the matter stays the same.
