the heat of reaction for a chemical reaction
Answer:
3 Cu²⁺(aq) + 2 PO₄³⁻(aq) ⇒ Cu₃(PO₄)₂(s)
Explanation:
Let's consider the molecular equation between aqueous copper(II) chloride and aqueous sodium phosphate.
3 CuCl₂(aq) + 2 Na₃PO₄(aq) ⇒ 6 NaCl(aq) + Cu₃(PO₄)₂(s)
The complete ionic equation includes all the ions and insoluble species.
3 Cu²⁺(aq) + 6 Cl⁻(aq) + 6 Na⁺(aq) + 2 PO₄³⁻(aq) ⇒ 6 Na⁺(aq) + 6 Cl⁻(aq) + Cu₃(PO₄)₂(s)
The net ionic equation includes only the ions that participate in the reaction (not spectator ions) and insoluble species.
3 Cu²⁺(aq) + 2 PO₄³⁻(aq) ⇒ Cu₃(PO₄)₂(s)
Answer:
Ag(I)C2H3O2 ....................
Silver only has a single valence value (+1) so you really don't need to put the (I) in the chemical formula.
Answer:
Approximately 206 grams.
Explanation:
How many moles of sulfuric acid
are there in this solution?
.
The unit for concentration "
" is equivalent to mole per liter. In other words,
. For this solution, the concentration of
is
.
.
What's the mass of that
of
?
Start by finding the molar mass
of
.
Relative atomic mass data from a modern periodic table:
- H: 1.008;
- S: 32.06;
- O: 15.999.
.
.
.
In other words, the chemist shall need approximately 206 grams of
to make this solution. As a side note, keep in mind that the 206 grams of
also take up considerable amount of space. Therefore it will take less than 5.00 L of water to make the 5.00 L solution.
