During what meterological (weather) changes does sublimation occur on earth?
insens350 [35]
Sublimation occurs more readily when definite weather circumstances are present such as low relative humidity and dry winds. Sublimation also occurs more at higher altitudes where the air pressure is less than at lower altitudes and energy such as strong sunlight is also needed. Sublimation happens a lot in the south face of Mt. Everest which have low temperatures, strong winds, intense sunlight, very low air pressure and the recipe for sublimation to occur.

What mass of sucrose needs to be dissolved in 540 g of water in order to prepare a 15% by mass solution.
Lilit [14]

Answer:

95.3g

Explanation:

Given parameters:

Mass of water  = 540g

Percentage by mass of solution = 15%

Unknown:

Mass of sucrose = ?

Solution;

To solve this problem, we must understand that a solution is made up of solute dissolved in a solvent. A solute is the solid dissolved in another. The solvent is the is dissolving medium;

    Percentage by mass of solute in solution = \frac{Mass of solute}{Mass of solution}  x 100

Mass of solution  = mass of water + Mass of sucrose  = 540 + M

  where M is the mass of sucrose;

therefore;

                 \frac{M}{540 + M }  x 100   = 15

   Solving for M gives 95.3g

Mass of sucrose is 95.3g

Which postulate of Dalton's atomic model was later changed and why?
fenix001 [56]

The postulate of Dalton's atomic theory that atom is indivisible particle and can be subdivided into smaller particles was later changed because atom can be divided into neutrons, protons and electrons. It was changed because after later finding out that the atom can be divided, the theory was changed to the correct finalized theory.

Hope this helps!!!
