Intermolecular forces are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions ). These forces are weak compared to the intramolecular forces, such as the covalent or ionic bonds between atoms in a molecule.
Answer:
D) 5.36 hours
Explanation:
According to mole concept:
1 mole of an atom contains number of particles.
We know that:
Charge on 1 electron =
Also, copper will produce 2 electrons. So, out of 5 moles of copper, 10 moles of electrons will be produced.
So,
Charge on 10 mole of electrons =
To calculate the time required, we use the equation:
where,
I = current passed = 50.0 A
q = total charge =
t = time required = ?
Putting values in above equation, we get:
Converting this into hours, we use the conversion factor:
1 hr = 3600 seconds
So,
Hence, the amount of time needed is 5.36 hrs.
When an acid is added to water, hydronium ions are formed.
What happens when the acid is added to water?
The acid has the ability to give protons that is hydrogen ions. When acid is added to water, water acts as base and takes up the protons released by the acid and forms hydronium ions that is H3O+ ions.
This process is exothermic in nature that is it releases heat. So acid is always added to water and not water to acid.
Therefore, when an acid is added to water, it gives hydronium ions in the water.
