Explanation:
Given parameters:
Equation of the reaction 2PbS + 30₂ → 2PbO + 2SO₂
Number of moles of 0₂ = 0.6moles
Unknown:
Mass of PbO produced = ?
Solution:
The number of moles is the quantity used in chemistry to express the amount of particles contained in a substance.
2PbS + 30₂ → 2PbO + 2SO₂
From the reaction;
3 moles of O₂ will produce 2 moles of PbO
0.6 moles of O₂ will then produce
= 0.4moles
Now since the we know the number of moles of PbO;
Mass of PbO = number of moles of PbO x molar mass
molar mass of PbO = 207.2 + 16 = 223.2g/mol
Mass of PbO = 0.6 x 223.2 = 133.92g

Answer:
C,H, O
Explanation:
glucose is made up of carbon, hydrogen and oxygen
Answer:
There are several methods - look at the explanation.
Explanation:
So first you can use cobal chloride paper which turns from blue to pink when water is present or you can use anhydrous copper sulfate which turns from white to blue and the blue substance would be called hydrated copper sulfate which is formed when water and anhydrous copper sulfate mix.
He combustion reaction of hexane:
2 C6H14 + 19 O2 = 12 CO2 + 14 H2O
2 mol C6H14 ---------> 12 mol CO2
x mol C6H14 ---------> 18.4 mol CO2
12 * x = 18.4 * 2
12 x = 36.8
x = 36.8 / 12
x = 3.067 moles of CO2

Well, it introduced atoms in this world and their functions. When the theory of atoms were created many more theory's came and we slowly figure out what the atoms do and what their functions are. The theory of an atom really surprised people because most of the people never knew the possibility of having living things inside of them.
Hope this helps.
