Answer:
d. 1.2 × 1024
Explanation:
From the equation of reaction
2H2 + O2= 2H2O
i.e 2mole(4g) of hydrogen requires 1 mole(32g) of oxygen to produce 2mole (2×6.02×10^23 molecules) of H2O= 1.2×20^24 molcules of water.
NB: 1 mole of H2O contains 6.02×10^23 molecules of H2O
Answer:
If another scientist give better reasons;if they tested their hypothesis and it was wrong; if someone proved whatever the idea was to be wrong
Explanation:
I mean the list can go on at this point
Empirical formula is the simplest way the molecular formula can be wrote so here 7 goes into all of these so it would be CH2O
Answer:
10.35
Explanation:
multiply moles by molar mass from periodic table
