Answer:
Explanation:
El porcentaje masa a masa de la solución se obtiene al dividir la masa del cloruro de sodio por la masa del agua (The mass-mass percentage of solution is obtained by dividing the mass of sodium chloride by the mass of water):

The reason is because IEs are usually reported from the neutral atom, that is, IE2 is the energy required to remove two electrons from a neutral Li atom, as above, rather than the additional energy required to remove one more electron from an Li+ cation.
The mass of titanium alloy is 7.01 g
<u><em>calculation</em></u>
Q=mHF
where
Q(heat)= 2960 j
M(mass) = ?
Hf( heat of fusion) = 422.5 j/g
make M the subject of the formula by diving both side of equation by Hf
M=Q/Hf
M= 2960 j/422.5 j/g = 7.01 g
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.
