By what factor would the average kinetic energy of the particles by increased if the temperature of a substance was increased fr
natita [175]
Average kinetic energy of a particle :
0.5 mv^2 = kT/2
so the kinetic energy = kT/2
assuming the same value of K
T1 = -49 + 273 = 224
T2 = 287 + 273 = 560

E2 / E1 = kT2 / 2 / kT1 / 2
E2 / E1 = T2 / T1
E2 / E1 = 560 / 224 = 2.5
so the average kinetic energy of the particle increases by 2.5

What is the hydrogen ion concentration of a solution with pH=8.25 ?
77julia77 [94]

Answer:

The answer is

<h2>5.62 \times  {10}^{ - 9} \:  M</h2>

Explanation:

The pH of a solution can be found by using the formula

pH =  -  log( {H}^{ + } )

where

{H}^{ + } is the hydrogen ion concentration of the solution

From the question

pH = 8.25

The hydrogen ion concentration of the solution is

8.25 =  -  log( {H}^{ + } )

<u>Find antilog of both sides</u>

That's

{H}^{ + }  =  {10}^{ - 8.25}  \\  = 5.62 \times  {10}^{ - 9} \:  M

We have the final answer as

5.62 \times  {10}^{ - 9} \:  M \\

Hope this helps you
