pH ranges depending on the solution, for a solution with weak acid pH will be between 4.0-7.0.
<h3>What is pH?</h3>
pH is helps to determine if a solution is acidic or basic in nature.
A pH meter is the instrument that can be used for the measurements.
Methyl orange is used when titrating a strong acid against a weak base.
Therefore, the pH of the solution which is a weak acid will be between 4.0-7.0.

The formula for molariy is nomber of moles/volume
0.5=n/1=>n=0.5 moles
one mole contains 6.023*10^23 molecules
so 0.5 contain 3.0115*10^23 molecules
A neutral atom contains the same number of electrons as protons and that means that the electric charge of the atom is neutral or otherwise known as zero. However, if a particular atom loses an electron, the atom becomes positively charged because there is more protons than electrons.
THIS IS CALLED A CATION.

Answer:
Seafloor spreading and other tectonic activity processes are the result of mantle convection. ... Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
