A company uses chlorine to produce titanium chloride from titanium dioxide.
What is the relative formula mass (Mr) of titanium dioxide, TiO2?
Relative atomic masses (Ar): O = 16 Ti = 48 *
Answer:
80 g/mol
Explanation:
The Relative formular mass is the sum of the relative atomic masses of the elements present in the molecule.
TiO2;
There is one Ti atom and 2 O atom. Their atomic masses is given as;
TiO2 = 48 + 2(16) = 48 + 32 = 80 g/mol

Lithium 1s22s1
Chlorine 1s22s22p6 3s23p5
A. 1:1
B. 1:2
C. 2:1
D. 3:1
D. 3:1
Answer:
A. 1:1
Explanation:
Lithium 1s2 2s1
Chlorine 1s2 2s2 2p6 3s2 3p5
Lithium is a group 1 element. When it forms a compound, it loses it's one valence (outermost) electron.
Chlorine is a group 7 element. When it forms a compound, it gains one electron to achieve a stable electronic configuration.
Since Li loses one electron and Cl gains one electron. The formular of the compound formed would be;
LiCl
The correct option is;
A. 1:1

2 Hgo 2 Hg + O2
1. How many grams of mercury (Hg) can be
produced from 3.55 moles of Hgo?
Answer:
712 moles of Hg are produced
Explanation:
Based on the reaction:
2HgO → 2Hg + O₂
Where 2 moles of HgO reacts producing 2 moles of Hg and 1 mole of O₂
To solve this question we need to find the moles of Hg produced, then, using its molar mass:
Moles Hg:
3.55mol HgO * (2 mol Hg / 2 mol HgO) = 3.55 mol Hg
Grams -Molar mass Hg: 200.59g/mol-:
3.55mol Hg * (200.59g/mol) =
712 moles of Hg are produced
