Question 2 [3]
A radioactive substance is decaying at a rate represented by y = h(t) = Roa', in millirems per
hour.
If 0 < a < 1 and the initial quantity of the subtance is Ro millirems, represent the quantity that
remains after 24 hours in terms of the function h.​

the formula would be mgso4

mgso[subscript]4

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

c) should be the answer.
