Extra pointsss 1. a solution at 25 degrees celsius is 1.0 × 10–5 m h3o+. what is the concentration of oh– in this solution?

1.0 × 10–5 m oh–

1.0 × 10–14 m oh–

1.0 × 105 m oh–

1.0 × 10–9 m oh–

Concentration of OH⁻:

1.0 × 10⁻⁹ M.

Explanation:

The following equilibrium goes on in aqueous solutions:

.

The equilibrium constant for this reaction is called the self-ionization constant of water:

.

Note that water isn't part of this constant.

The value of at 25 °C is . How to memorize this value?

Back to this question. is given. 25 °C implies that . As a result,

.

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.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
