Answer:
iron oxidizes
Explanation:
Being a solid, melting, and attraction are all physical properties.
Answer:
Atomic Number: 1
Atomic Mass: 1
Explanation:
Atomic number = # of protons
Atomic mass = # of protons + # of neutrons
Answer:
H2SO4
Explanation:
Firstly,
2.056% hydrogen = 2.056g of H
32.69% Sulphur = 32.69g of S
65.26% oxygen = 65.26g of O
Next, we convert each mass into moles by dividing by their respective molar mass:
H = 1, S = 32, O = 16
H = 2.056/1 = 2.056mol
S = 32.69/32 = 1.021mol
O = 65.26/16 = 4.078mol
Next, we divide each mole value by the smallest mole value (1.021)
H = 2.056/1.021 = 2.01
S = 1.021/1.021 = 1
O = 4.078/1.021 = 3.99
Approximately the ratio of H to S to O is 2:1:4, hence, the empirical formula for H, S and O is H2SO4.
