Suppose 50.0 ml of 0.125 M HCl is mixed with 75.0 ml of 0.200 M Ca(OH)2.

a) Calculate the concentration, in moles per liter, of each of the ions present after mixing. Assume that the volumes are additive.

b) Which is greater, moles of H+ or moles of OH-?

c) How much more of the greater one do you have? Determine the concentration.

The image shows a process that releases nuclear energy which statement best identifies the process shown the process must be fusion because energy is released the process must be fusion because of have your nucleus formed a smaller nuclei the process must be fission because a large nucleus breaks into smaller nuclei the process must be fission because neutrons are formed

What will most likely happen when two bromine atoms bond together?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
