1. i have a concentration of 300g of sugar for every 100 ml of water. what is the lowest possible temperature i would need to dissolve that much sugar?

64 °C

Explanation:

I’m guessing that “they” are asking you to interpret a solubility curve something like the one below.

Find the point at 300 g/100 mL water on the vertical axis.

From there, draw a horizontal line until it meets the solubility curve of sugar.

Then, drop a vertical line to the temperature axis.

It appears to hit the axis at about 64 °C.

The solution is saturated at this temperature, so 64 °C is the lowest temperature at which you can dissolve 300 g of sugar in 100 mL of water.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
