Given the balanced equation 2(h2 s) + 3(o2) = 2(s o2) + (h2 o)
what is the correct mole ratio set?
h2 s: s o2 = 2: 2 , o2: h2 o
2: 2, 3: 2
2: 3, 3: 2
4: 4, 5: 4
4: 6, 4: 4

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

The table describes how some substances were formed substance 19 description formed by boiling pure water formed by combining three hydrogen atoms to every nitrogen atom formed by adding 5 g of sugar to 1 l of water formed by compressing carbon under high pressure based on the given descriptions, which substance is most likely a mixture?

Water's surface tension and heat storage capacity are accounted for by its a) orbitals b) weight c) hydrogen bonds d) mass e) size
