Equal volumes of two solutions, one containing a strong acid at pH 2 and the other containing a strong base at pH 12, are mixed.
mash [69]

Answer:

7  

Explanation:

Assume we have 1 L of each solution.

Solution 1

\text{[H$^{+}$]}= 10^\text{-pH} \text{ mol/L} = 10^{\text{-2}} \text{ mol/L}\\ \text{ moles of H}^{+} = \text{ 1 L solution} \times \dfrac{10^{-2}\text{ mol H}^{+}}{\text{1 L solution}} = 10^{-2}\text{ mol H}^{+}

Solution 2

pH = 12

pOH = 14.00 - pOH = 14.00 - 12 = 2.0

\text{[OH$^{-}$]}= 10^\text{-pOH} \text{ mol/L} = 10^{\text{-2}} \text{ mol/L}\\ \text{ moles of OH}^{-} = \text{ 1 L solution} \times \dfrac{10^{-2}\text{ mol OH}^{-}}{\text{1 L solution}} = 10^{-2}\text{ mol OH}^{-}

3. pH after mixing

               H⁺  +  OH⁻ ⟶ H₂O

I/mol:     10⁻²    10⁻²  

C/mol:   -10⁻²   -10⁻²

E/mol:      0        0

The H⁺ and OH⁻ have neutralized each other. The pH will be that of pure water.

pH = 7

What is the purpose of a switch in an electrical circuit?
dmitriy555 [2]
The purpose of a switch in a series circuit is to make it easy to open or close the electrical circuit, turning the flow of electricity on or off. A light bulb in a series circuit is used to determine whether or not electricity is flowing.

The parent element 247 95 am decays by beta decay which daughter element will formn
ziro4ka [17]
Atomic mass of the parent element =247,
atomic number of the parent element = 95

In the process of β-decay electron leaves the nucleus, so instead of one neutron we get one proton.

Mass of proton≈mass of neutron,
so atomic mass will not change.

Charge of proton =+1, and charge of neutron = 0.
So, we will get atomic number increased by one.

New element (daughter) will have 
atomic mass = 247, 
and atomic number= 95+1=96

Number 95 - Am (parent),
number 96 - Cm(daughter),

So, from Am-247 we will get Cm-247.
