Answer and explanation:
Initially, the pH of the solution will be determined by the dissociation of the weak acid.
Usually, this kind of solution consists of a mixture of weak acid that has not yet reacted and the salt that will be formed by the reaction of the weak acid with a strong base that has been added.
After the dissociation process, the pH will be more affected due to the excess of base in the solution.
It depends on what unit/subject you're looking at.
Because in physics, I know that if you are considering Newton's theory of particles, all particles technically go in a straight line from the original direction. BUT, if you're looking at the Wave of the Particle theory, then you would assume that particles do not necessarily follow the above b/c they follow the properties of a wave...
Answer:
0.25 mole of H₂
Explanation:
The equation for the reaction is given below:
Mg + 2HCl —> MgCl₂ + H₂
From the question given above, we were told that the reaction produced 5.6 L of H₂.
Thus, we can obtain obtain the number of mole of H₂ that occupied 5.6 L at STP as follow:
1 mole of H₂ occupied 22.4 L at STP.
Therefore, Xmol of H₂ will occupy 5.6 L at STP i.e
Xmol of H₂ = 5.6 / 22.4
Xmol of H₂ = 0.25 mole
Therefore, 0.25 mole of H₂ were obtained from the reaction.
