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!

7. in the cycle, a virus integrates its dna into the host's dna, and its dna is replicated when the host dna is replicated. a. infectious b. retroviral c. lysogenic d. lytic

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.

What is a number added in front of a formula in order to balance the equation
