I'm learning this so... protons and electrons are the same number. that's all I can tell you. I'm still learning it.
Answer:
D.
Explanation:
The weighted average of the masses of the isotopes.
Answer: at low pressure and high temperature.
The real gases deviate from ideal gases at high pressures and low temperatures, because high pressure and low temperatures reduce the free space between the particles and their velocities, causing that the effect of the volume of the particles of the gas and the intermolecular forces be more important.
The lower the pressure and the higher the temperatures the less the effect of the volume of the particles and of the intermolecular forces. Remember that ideal gas theory considers that individual particles do not occupy space and they do not intereact one to each other (except for the collisions).
Answer: The pH at the equivalence point for the titration will be 0.65.
Solution:
Let the concentration of be x
Initial concentration of , c = 0.230 M
at eq'm c-x x x
Expression of :
Since ,methyl-amine is a weak base,c>>x so .
Solving for x, we get:
Given, HCl with 0.230 M , it dissociates fully in water which means = 0.230 M
will result in neutral solution, since
Remaining after neutralizing ions
The pH at the equivalence point for the titration will be 0.65.
Answer:
C stays same
Explanation:
Law of conversation of mass state that mass remain same during hating or chemical reaction
