A. An element in its pure state is always 0.
B. One of the oxidation rules is that H with a nonmetal (which is Cl) is always +1. Cl would be -2 because -2 + (+1) equals -1.
C. Oxygen is always -2, so Cl- would have to be -1 to equal -3.
It has been awhile since I learnt this in AP Chem so answers could be a little rusty. Hopefully it helps.
From the equation, 32 equiv dixoygen gas evolve from 1 equiv chlorate.
You started with 6 equiv chlorate, and thus 9 equiv dioxygen gas are evolved. This is a common undergrad experiment. I think you need to add some sort of manganese oxide catalyst.
Answer:
temperature, refractive index, density, and hardness of an object
Explanation:
it is a bulk property, meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system
Answer:
choice A
Explanation:
it it occurs when a gas escapes from a container through a hole of diameter.
Moles of ZnSO4 = Mass/Mr
= 2/(65.4 + 32.1 + (16 x 4))
= 0.012383.... mol
Since there is no chemical equation provided, I will assume that the ratio of ZnSO4:Li2CO3 is 1:1
Therefore there are 0.012383 mil of Li2SO4 as well
So the mass would be Moles x Mr = 0.012383.... x ((6.9 x 2) +32.1 + (4x16))
= 1.360 g of Li2SO4 produced
