C because it’s reshaping it, it stays the same but just reshaping it
For a 100-g compound, we would have 2 g H, 32.7 g S, and 65.3 g O. We then divide each of these masses by their molar masses:
2 g H / 1.01 g/mol = 1.98 mol H
32.7 g S / 32.07 g/mol = 1.0196 mol S
65.3 g O / 16.00 g/mol = 4.08125 mol O
We then divide each amount of moles by the smallest of them, which is the 1.0196 from S:
1.98 mol H / 1.0196 mol S = 1.94 H ~ 2 H
1.0196 mol S / 1.0196 mol S = 1 S
4.08125 mol O / 1.0196 mol S = 4 O
So the empirical formula of the compound is H2SO4.
Answer:
0.020 kg=20 g this the largest
20.0 mg=.020g
.200g
2000ug
Explanation:
Explanation:
heliocentric means having the sun in the middle/center in the solar system
geocentric means having the earth in the middle/center in the solar system
therefore your answers are:
the planets orbit the sun.
in 1543, Nicolaus Copernicus proposed the theory.
the evidence that led people to believe this was when Galileo observed that four moons orbited around Jupiter. in other words, heliocentric.
most of the stars are located in the milky way galaxy.
