PLEASE HELP ME! ASSIGNMENT DUE ASAP! will give you brainliest! (a) Consider the following half equations.
SO3^2-+ H2O --> SO4^2- + 2H^+1 + 2e-
...and...
MnO4^- + 8H^+ + 5e- --> Mn^2+ + 4H2O

Combine these two equations to obtain the overall reaction of sulfite ions with manganate (VII) ions.
(2)

(b)Use the equation you have written in (a) to calculate the volume of 0.277 M manganate (VII) ions that are required to react completely with 20.0 mL of 0.451 M sulfite ions. (4)

-I just need to know how to get the answer-Thanks!

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

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.
