Why do non metallic elements pull electrons from metallic elements so effectively during a reaction?

1 answer:

8 0

Non metallic elements pull electrons from metallic elements so effectively during a reaction because they have a tendency to gain electrons and tend to be small in size.
Non metallic elements have higher electronegativities than metals. The atoms of nonmetals tend to gain electrons in order to acquire a noble gas electron configuration. This gives them a net negative electric charge.

When 220 mL of 1.50x10^-4 M hydrochloric acid is added to 135 mL of 1.75x10^-4 M Mg(OH)2, the resulting solution will be________

siniylev [52]

Answer:

Basic

Explanation:

Considering

$Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}$

So,

$Moles =Molarity \times {Volume\ of\ the\ solution}$

For hydrochloric acid :

Molarity = $1.50\times 10^{-4}$ M

Volume = 220 mL

The conversion of mL to L is shown below:

1 mL = 10⁻³ L

Thus, volume = 220×10⁻³ L

$Moles =1.50\times 10^{-4} \times {220\times 10^{-3}}\ moles$

Moles of hydrochloric acid = 0.000033 moles

For $Mg(OH)_2$ :

Molarity = $1.75\times 10^{-4}$ M

Volume = 135 mL

The conversion of mL to L is shown below:

1 mL = 10⁻³ L

Thus, volume = 135×10⁻³ L

$Moles =1.75\times 10^{-4} \times {135\times 10^{-3}}\ moles$

Moles of $Mg(OH)_2$ = 0.000024 moles

According to the given reaction:

$Mg(OH)_2_{(aq)}+2HCl_{(aq)}\rightarrow MgCl_2_{(s)}+2H_2O_{(aq)}$

1 mole of $Mg(OH)_2$ reacts with 2 moles of HCl

Also,

0.000024 mole of $Mg(OH)_2$ reacts with 2*0.000024 moles of HCl

Moles of HCl = 0.000048 moles

Available moles of HCl = 0.000033 moles

Limiting reagent is the one which is present in small amount. Thus, HCl is limiting reagent.

Thus, HCL will be consumed completely and $Mg(OH)_2$ will be left over. Thus, the resulting solution will be basic.

What causes hydrogen bonds to rupture in ice

finlep [7]

As water is boiled, kinetic energy causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas (steam or water vapor). When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water.
