non matter=Light, heat, kinetic and potential energy, and sound are non-matter because they are massless
Answer:
9
Explanation:
Given parameters:
Concentration of OH⁻ [OH]= 1 x 10⁻⁹M
Solution:
To find the pOH of a solution can be found using the expression below:
pOH = -log₁₀[OH]
[OH] = concentration of the hydroxyl ions
pOH = -log₁₀(1 x 10⁻⁹) = - x -9 = 9
Answer:
the sum of average kinetic molecules of the body is called temperature..
