What is the pH of the solution if the [H+] is 1 x 10-12 ?
jarptica [38.1K]

Answer:

<h2>12</h2>

Explanation:

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

pH = - log [ {H}^{+} ]

From the question we have

pH =  -  log(1 \times  {10}^{ - 12} )  \\

We have the final answer as

<h3>12</h3>

Hope this helps you

In a coffee-cup calorimeter, 100.0 g of H2O and 100.0 mL of 1M HCl are mixed. The HCl had an initial temperature of 44.6 C and t
Hatshy [7]

Answer:

Exothermic reaction for the HCl, endothermic reaction for the water

2803.28\ \text{J}

Explanation:

Heat was lost by HCl as its temperature lowered, so it was an exothermic reaction for the HCL.

Heat was gained by water as its temperature increased, so it was an endothermic reaction for the water.

m = Mass of water = 100 g

c = Specific heat of water = 4184\ \text{J/kg}^{\circ}\text{C}

\Delta T = Change in temperature of water = (31.3-24.6)^{\circ}\text{C}

Heat is given by

Q=mc\Delta T\\ =0.1\times 4184\times (31.3-24.6)\\ =2803.28\ \text{J}

Heat gained by water is 2803.28\ \text{J}.

A substance registers a temperature change from 20 to 40 to what incremental temperature change does this correspond
ss7ja [257]

<u>Given:</u>

Initial temperature, T1 = 20 C

Final temperature, T2 = 40 C

<u>To determine:</u>

The temperature change

<u>Explanation:</u>

Convert degree C to Kelvin

Temperature in Kelvin = degree C + 273

T1 = 20 + 273 = 293 K

T2 = 40 + 273 = 313 K

Incremental temperature change = T2 - T1 = 313-293 = 20 K

Ans: The temperature change in kelvin is 20 K
