Answer:
None of the options are correct.
Explanation:
1) when the temperature of the solution is increased the solubility of the gas in the liquid decreases , hence option 1 is incorrect.
2)The heat released by the dissolution of an ionic compound in water is heat of hydration of the compound and is independent of the initial temperature of the solution.
3) The solubility of a liquid in water is not affected significantly by the pressure changes in the system as gases only have a significant cahne in solubility with change in pressure.
The answer is 6 ft 10 inches in millimeters (mm) is 0.833 ft.
Given,
The center of the school's basketball team is 6 ft 10 inches tall.
We have to convert the height of the player from feet and inches to feet.
Using the conversion factor,
1 ft = 12 inches
or, 12inches/ 1 ft
Converting 6ft 10 inches to ft, we get;
10 inches × 1 ft/ 12inches
= 0.833 ft
Therefore 6 ft 10 inches in millimeters (mm) is 0.833 ft.
Unit conversion is a method in which we multiply or divide with a particular numerical factor and then finally round off to the nearest significant digits.

The Bohr Model, which was proposed by Niels Bohr in 1913
Answer:
709 g
Step-by-step explanation:
a) Balanced equation
Normally, we would need a balanced chemical equation.
However, we can get by with a partial equation, as log as carbon atoms are balanced.
We know we will need an equation with masses and molar masses, so let’s <em>gather all the information</em> in one place.
M_r: 30.07 236.74
C₂H₆ + … ⟶ C₂Cl₆ + …
m/g: 90.0
(i) Calculate the moles of C₂H₆
n = 90.0 g C₂H₆ × (1 mol C₂H₆ /30.07 g C₂H₆)
= 2.993 mol C₂H₆
(ii) Calculate the moles of C₂Cl₆
The molar ratio is (1 mol C₂Cl₆/1 mol C₂H₆)
n = 2.993 mol C₂H₆ × (1 mol C₂Cl₆/1 mol C₂H₆)
= 2.993 mol C₂Cl₆
(iii) Calculate the mass of C₂Cl₆
m = 2.993 mol C₂Cl₆ × (236.74 g C₂Cl₆/1 mol C₂Cl₆)
m = 709 g C₂Cl₆
The reaction produces 709 g C₂Cl₆.
