Concept explainers
(a)
Interpretation:
The formula and name of the compound that is formed by the reaction of titanium and chlorine at 300°C needs to be determined. It contains 25.25% of Ti by mass. The molecular formula and empirical formula are assumed to be same for the compound.
Concept introduction:
The group 7A elements show variation from non-metals to metals down in the group. The first element of the group 7A is fluorine with 7 valence electrons. These elements forms halide with metals and exist in X-1 ionic state.
(b)
Interpretation:
The balance equation for the reaction of Ti with chlorine at 300°C needs to be determined.
Concept introduction:
In a balanced chemical equation, the number of atoms of same elements is equal on both side of the reaction arrow.
(c)
Interpretation:
The balance equation for the reaction of TiCl4 with Mg that forms pure titanium metal needs to be determined.
Concept introduction:
In a balanced chemical equation, the number of atoms of same elements is equal on both side of the reaction arrow.

Show that the change in entropy for a fixed amount of ideal gas held at a constant temperature undergoing a volume change is given by the simple equation AS = NkB In Hint: Start with the equation M dS = du + (Œ) dv - Ž (#) an, dU du+av-dN; j=1 Why doesn't the equation for the entropy of an ideal gas depend on the strength of the intermolecular forces for the gas?arrow_forward
- 2. Make an ice cube at 1 bar pressure by freezing an amount of liquid water that is 2 cm x 2 cm x 2 cm in volume. The density of liquid water at 0 °C is 1.000 g cm³ and the density of ice at 0 °C is 0.915 g cm³. Note that this difference in density is the reason your water pipes burst if they freeze and why you shouldn't forget to take your bottle of pop out of the freezer if you put it in there to try and cool it down faster.
