Chemistry

The iron uses heat waves to flatten the shirt. You can also you water to help the process and create steam. The steam will help soften the shirt making it easier to flatten. I am not sure if this is correct but it should help to understand why the shirt gets hot.

Un medicamento corresponde a una disolución de "nafazolina" (sustancia activa) en agua purificada, en una concentración de 12% V
ratelena [41]

Según la pregunta;

V / V% concentración del fármaco = 12%

volumen de la solución = 100 ml

De;

V / V% = volumen de fármaco / volumen de solución

volumen de fármaco = V / V% × volumen de solución

volumen de fármaco = 12/100 × 100

= 12 mL

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
