Answer:
The chemist needs to react 40 g of sulfur with 60 g of oxygen to make 100 g of sulfur trioxide.
Explanation:
2S (s) + 3O₂ (g) → 2SO₃ (g)
64g + 96g → 160 g
32g + 48g → 80 g
x + y → 100 g
1 mol SO₃ ___ 80g
n _______ 100g
n = 1.25 mol SO₃
1 mol S ___ 32 g
1,25 mol S __ 40 g
1 mol O₂ ___ 32 g
1,875 mol O₂ ___ 60 g
Answer:
3
Explanation:
the answer is 3 because it is 3 for the o2 so 3 you <em>have </em><em>to </em><em>pay </em><em>more </em><em>attention </em><em>for </em><em>the </em><em>small </em><em>ditails </em>
Answer:
<u>Metalloid -</u>
A metalloid is a chemical element with properties intermediate between those of typical metals and nonmetals
<u>Alloy</u> -
An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by a metallic bonding character.
D, obviously. All living things are made of one or more cells, therefore non-living things aren’t made of cells
