In the lab, you have three samples of equal concentration: acetic acid, hydrochloric acid, and sulfuric acid. a) How would the pH of each acid compare? Explain. b) If each was used separately in a titration of sodium hydroxide, how would the volume of each acid compare?

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
