Answer:
See explanation
Explanation:
An unbalanced chemical equation does not show equal number of atoms of each element on both sides of the reaction equation.
a) KOH + H3PO4 -----> K3PO4 + 3H20
b) Zn + AgCl -------> ZnCl2 + Ag
c) NaHCO3 → Na2CO3 + H2O + CO2
d) NH4NO2 ------> N2 + H2O
e) CO2 + KOH -----> K2CO3 + H2O
<span>Carbon has different isotopes. What is different between an atom of 12C and an atom of 13C?
Question 7 options:
A.number of protons in the nucleus
B.number of electrons in the atom
C.number of protons and electrons in the atom This is correct.
D.number of neutrons in the nucleus</span>
Balanced chemical reaction: 2HI(aq) + Ba(OH)₂(aq) → BaI₂(aq) + 2H₂O(l).
Ionic reaction: 2H⁺ + I⁻(aq) + Ba²⁺ + 2OH⁻(aq) → Ba²⁺ + 2I⁻(aq) + 2H₂O(l).
Net ionic reaction: 2H⁺ + 2OH⁻(aq) → 2H₂O(l).
Barium iodide is salt that dissolves in water, barium hydroxide is strong base that dissolves in water.
This is example of double replacement reactions(double displacement or metathesis reactions), two ionic compounds are exchanged, making two new compounds

To solve this equation you can use a basic molarity formula and substitute the correct values.
The formula for molarity is M = mol/L.
Start by changing your mL to L. To do this, divide 25 by 1000.
This results in:
.025 L
You can now rearrange your molarity formula to isolate what you are solving for, which is moles.
This leaves your formula as:
ML = mol
Now, plug in your converted volume and given molarity into the formula.
This leaves you with:
(0.100)(0.025) = mol
Multiply to find your final value for moles.
This results in:
0.0025 mol of HNO3
