How many molecules are there in 5H20? A.5 B.7 C.10 D.11

Chemistry

I believe 11.

Since the first 5 is in the outside, it’s 5 times the number.

In H2O there are already 2 hydrogen and 1 oxygen molecule, totaling to 3.

When you put 5 H2’s, and add them, that would equal 10 molecules, plus the O on the end, would equal 11.

How did Rutherford's gold foil experiment show that Thomson's plum pudding model of the atom was
Ket [755]

Answer:

He blasted alpha rays at the gold foils. The Alpha rays are charged positive. When he blasted them the protons deflected and changed the course of them and the electrons surrounding the atom let them through. In the plum pudding model they were supposed to be sprinkled on which was clearly wrong according to that experiment.

Find the volume of 20g of H₂ at STP<br><br>​
ANEK [815]

Answer:224

Explanation:

We should answer it with Stoichiometry

We say: 20 g H2× (1 mol/ 2g)× ( 22.4 lit/ 1 mol) = 224

Means: we have 20 grams and every 2g H2, equals to 1 mol of it and every 1 mol of H2, equals to 22.4 lit( because of STP)

hope you got this:)
