HNO₃(aq) +Ca(OH)₂(aq) --> H₂O(l) + Ca(NO₃)₂(aq)

It is Ca(NO₃)₂ because NO₃ has a charge of -1, and Ca has a charge of 2+. And when writing an ionic compound, you take the charge of 1 and write it as the subscript of the other.

Now let's balance the equation and then find the net ionic equation.
2HNO₃(aq) +Ca(OH)₂(aq) --> 2H₂O(l) + Ca(NO₃)₂(aq)

2H⁺(aq) + 2NO₃⁻(aq) + Ca²⁺(aq) + 2OH⁻(aq) --> 2H₂O(l) + Ca²⁺(aq) + 2NO₃⁻(aq)

We can get rid of the spectator ions. These are the ions that are on both sides.
We are left with 
2H⁺(aq) + 2OH⁻(aq) --> 2H₂O(l)

We can simplify the net ionic equation down to
H⁺(aq) + OH⁻(aq) --> H₂O(l)

Please help! If a forensic chemist discovers evidence through examination which would prove a person guilty of a crime, why then
Bogdan [553]

Explanation: You cannot be convicted of a crime without evidence. You cannot be convicted of a state crime. You cannot be convicted of a federal crime. If there is no evidence against you, under the law, it simply is not possible for the prosecutor's office to obtain a conviction at trial. So, when you do have evidence it is really impossible to not get convicted unless the judge truly believes your side of the story and declares you not guilty.

I hope this helped :) If not i'm sorry!

what is the concentration of a dextrose solution prepared by diluting 14 ml of a 1.0 m dextrose solution to 25 ml using a 25 ml
allsm [11]

The concentration of a dextrose solution prepared by diluting 14 ml of a 1.0 M dextrose solution to 25 ml using a 25 ml volumetric flask is 0.56M.

Concentration is defined as the number of moles of a solute present in the specific volume of a solution.

According to the dilution law, the degree of ionization increases on a dilution and it is inversely proportional to the square root of concentration. The degree of dissociation of an acid is directly proportional to the square root of a volume.

M₁V₁=M₂V₂

Where, M₁=1.0M, V₁=14ml, M₂=?, V₂=25ml

Rearrange the formula for M₂

M₂=(M₁V₁/V₂)

Plug all the values in the formula

M₂=(1.0M×14 ml/25 ml)

M₂=14 M/25

M₂=0.56 M

Therefore, the concentration of a dextrose solution after the dilution is 0.56M.
