According to Le Chatelier's Principle, to increase the rate of the forward reaction we add more of the reactants to encourage more collisions and production of more products. If it is endothermic, more heat should be added. If it is endothermic, more heat should be released from the system.
The correct answer would be 2
Once heat from the sun penetrate the Earths atmosphere, the heat is circulated as warm air rises and cold air sinks,this process is called convection Convection can be demonstrated by placing a heat source {cooker} at the side of a glass full of a liquid, and observing the changes in temperature in the glass caused by the warmer fluid moving into cooler areas
In this redox reaction, we must identify which is reduced and which is oxidized. Cl is oxidized from -1 to 0, Mn is reduced from +7 to +2.
<span>MnO−4+Cl−→Mn2++Cl2</span>Balance the number of Cl first.
<span>MnO−4+2Cl−→Mn2++C<span>l2
</span></span><span>MnO−4+10Cl−→2M<span>n2+</span>+5C<span>l2
</span></span>Balance the number of oxygen by adding <span>H2O</span>
<span>2MnO−4+10Cl−→2M<span>n2+</span>+5Cl2+8H2O
</span>Balance the number of H by adding H+
<span>2MnO−4+10Cl−+16H+→2M<span>n2+</span>+5Cl2+8H2O
</span>
Now, we know that there are 2 H+ in <span>H2SO4</span>, so, we can get
<span>2MnO−4+10Cl−+8H2SO4→2M<span>n2+</span>+5Cl2+8H2O
</span>
Put <span>S<span>O2−4</span></span> with <span>M<span>n2+</span></span>
<span>2MnO−4+10Cl−+8H2SO4→2MnSO4+5Cl2+8H2O
</span>
Add K in front of <span>MnO−4</span> and <span>Cl−</span> and balance it on the right
<span>2KMnO4+10KCl+8H2SO4→12K++2MnSO4+5C<span>l<span>2 + 8H20
The final answer is </span></span></span>2KMn<span>O4</span><span>+10KCl+8</span><span>H2</span><span>S</span><span>O4</span><span>→6</span><span>K2</span><span>S</span><span>O4</span><span>+2MnS</span><span>O4</span><span>+5C</span><span>l2</span><span>+8</span><span>H2</span><span>O</span>
94.63 mg/L as a unit of density is equivalent to 9.463 × 10-⁵ g/mL.
<h3>What is density?</h3>
Density is a measure of the mass of matter contained by a unit volume.
Density of a substance can be calculated by dividing the mass of the substance in grams by its volume in milllilitres. This means that the unit of measurement for density is g/mL.
However, the conversion factor of g/mL to mg/L is as follows:
1 gram/millilitre = 1000000 milligrams/litre
94.63 mg/L = 94.63 ÷ 1000000
= 9.463 × 10-⁵ g/mL
Therefore, 94.63 mg/L as a unit of density is equivalent to 9.463 × 10-⁵ g/mL.
