Answer:
686.43363984 is the answer when 7.8 moles is converted.
Reaction of Cu(NO₃)₂ with each salt is as follow,
1) with KNO₃;
Cu(NO₃)₂ + KNO₃ → Cu(NO₃)₂ + KNO₃
Both salt products are water soluble.
2) With CuSO₄;
Cu(NO₃)₂ + CuSO₄ → CuSO₄ + Cu(NO₃)₂
Again both Salt products are water soluble.
3) With K₂SO₄;
Cu(NO₃)₂ + K₂SO₄ → CuSO₄ + 2 KNO₃
Again both salt products are water soluble.
4) With K₂S;
Cu(NO₃)₂ + K₂S → CuS + 2 KNO₃
In this case CuS is water insoluble, hence precipitates out.
Result:
Option-4 is the correct answer.
Answer:
This equation is balanced.
Explanation:
To determine whether an equation is balanced or not, we must make sure that there are the same number of each type of atoms in both the reactants (on the left side of the equation) and the products (on the right side of the equation).
We can see that there are two atoms of nitrogen on the left side of the equation. When we look at the right side of the equation, we see that there are two molecules of NH6, with one atom of nitrogen each. Since 2 * 1 = 2, there are two atoms of nitrogen in the products as well. This means that the nitrogen atoms are balanced.
Next, we must look at the hydrogen atoms. There are 6 molecules of H2, which contains 2 atoms of hydrogen each. Since 6 * 2 = 12, there are 12 atoms of hydrogen in the reactants. On the right side of the equation, there are 2 molecules of NH6, which contains 6 atoms of hydrogen each. Since 2 * 6 = 12, there are 12 atoms of hydrogen in the products as well. Since there are 12 atoms on both sides of the equation, the hydrogen atoms are balanced.
Since both types of atoms that are presented in this equation are balanced, we can conclude that the overall equation is balanced.
Hope this helps!
Answer:
Al(NO₃)₃ + (NH₄)₃PO₄ —> AlPO₄ + 3NH₄NO₃
The coefficients are: 1, 1, 1, 3
Explanation:
__Al(NO₃)₃ + __(NH₄)₃PO₄ —> __AlPO₄ + __NH₄NO₃
The above equation can be balance as illustrated below:
Al(NO₃)₃ + (NH₄)₃PO₄ —> AlPO₄ + NH₄NO₃
There are 12 atoms of H on the left side and 4 atoms on the right side. It can be balance by writing 3 before NH₄NO₃ as shown below:
Al(NO₃)₃ + (NH₄)₃PO₄ —> AlPO₄ + 3NH₄NO₃
Now the equation is balanced.
The coefficients are: 1, 1, 1, 3
