Calculate the concentration of h3o⁺ in a solution that contains 6.25 × 10-9 m oh⁻ at 25°c. identify the solution as acidic, basic, or neutral. a) 6.38 × 10-9 m, basic b) 1.60 × 10-6 m, acidic c) 7.94 × 10-11 m, acidic d) 7.38 × 10-3 m, basic e) 4.92× 10-5 m, acidic

B) M, acidic

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration and pOH is calculated by taking negative logarithm of hydroxide ion concentration.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

Given :

As pH is less than 7, the solution is acidic.

Thus solution is acidic and concentration of is

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
