Answer: a tornado doesnt have an eye in the middle and its cause by wind and air but a hurricane is way different then a tornado a hurricane is only perduce by air and the force of it can damage more than a tornado and the hurricane also has an eye in the middle and its bigger than a tornado so its C
Explanation:
Sugar would not increase the boiling point of the water as much as the others.To show this, we recall the equation for boiling point elevation ∆t:
∆t = i Kb m
The difference in these four solutions will be in the product of the van't Hoff Factor i and molality m: i * m.
If we assume that we have 0.1m of each solute, the products i*m for these solutions are:
Solution Identity of particles i i * m
0.1 m NaCl Na+, Cl- 2 2 * 0.1 = 0.2
0.1 m MgSO4 Mg^2+, SO4^2- 2 2 * 0.1 = 0.2
0.1 m K2SO4 two K+, SO4^2- 3 3 * 0.1 = 0.3
0.1 m C12H22O11 covalently bonded molecules 1 1 * 0.1 = 0.1
Therefore, having the lowest i * m, sucrose will have the lowest boiling point elevation.
2,2-dichloroheptane because we have two Cl we should use the prefix ''di'' and the numbers "2" and "2" indicated that the two functional groups are located on the same second carbon
Answer:
a) 0.61 mol
Explanation:
165.3718 g Rubidium Bromide = 1 mol
100 g Rubidium Bromide = 1/165.3718 x 100
= 0.61 mol
