Answer:
2H+(aq) + 2OH-(aq) → 2H2O(l)
Explanation:
Step 1: The balanced equation
2HCl(aq)+Ca(OH)2(aq) → 2H2O(l)+CaCl2(aq)
This equation is balanced, we do not have the change any coefficients.
Step 2: The netionic equation
The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will.
2H+(aq) + 2Cl-(aq) + Ca^2+(aq) + 2OH-(aq) → 2H2O(l) + Ca^2+(aq) + 2Cl-(aq)
After canceling those spectator ions in both side, look like this:
2H+(aq) + 2OH-(aq) → 2H2O(l)
Single bonds are those that bond with one atom, and sigma bonds are the strongest type of covalent bonds that are single bonded.
That means NO, not all single bonds are sigma bond, but all sigma bonds are single bonds.
Answer:
Osmotic pressure and boiling point elevation
Explanation:
In the the osmotic pressure one can determine the molar mass of a solid by calculating the number of moles from the Morality formula which involves the volume of the solution.
In the boiling point elevation you can determine the number of moles of the solute in the solution by using the Molality formula.
Answer: 22 neutrons
Explanation: 40 is the mass number = atomic mass = total number of protons and neutrons in atomic nucleus
18 is the number of protons in the nucleus of this atom
Then 40 - 18 = 22 neutrons
and this is Argon
The atoms in a metal are held together by electrostatic forces called metallic bonds.
