Answer:
if you add or subtract a neutron from an atom it will become a new isotopes of the same element
When discussing discordant and harmonious sound waves, the statement tat is false is : if the original waves combine to form irregular displacement of air, the sound will be discordant. The fact is, irregular displacement of air does not guarantee sound discordance
hope this helps
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>
