Answer:
(a) 
(b) Rubidium
Explanation:
Hello,
This titration is carried out by assuming that the volume of base doesn't have a significant change when the mass is added, thus, we state the following data a apply the down below formula to compute the molarity of the base solution:

Solving for the molarity of base we've got:

Now, we can compute the moles of the base as:

(a) Now, one divides the provided mass over the previously computed moles to get the molecular mass of the unknown base:

(b) Subtracting the atomic mass of oxygen and hydrogen, the metal's atomic mass turns out into:

So, that atomic mass dovetails to the Rubidium's atomic mass.
Best regards.
Answer:
For any cross between Homozygous dominant and Homozygous recessive individual the offspring will always be 100% Heterozygous dominant, that is all will have Rr.
Explanation:
Answer:
increasing the temperature
Explanation:
Le Châtelier's principle for an endothermic reaction states that when a stress is added on the system it causes the stress to shift to the direction where the stress can be reduced in other for equilibrium can be achieved.in this case an increase in temperature results in the increase in number of moles of carbon dioxide
