Answer:

grams of lithium bromide produced = 36.2642309286  ≈ 36.30 g

Explanation:

The equation of the reaction is as follows ;

Lithium hydroxide + hydrogen bromide → Lithium Bromide + water

LiOH + HBr → LiBr + H2O

The equation is already balanced

Molecular mass of LiOH = 6.941  + 15.999 + 1.00784

Molecular mass of LiOH = 23.94784  g

Molecular mass of LiBr = 6.941 + 79.904 = 86.845  g

From the equation

LiOH + HBr → LiBr + H2O

23.94784  g of lithium hydroxide produces 86.845  g of lithium bromide

10 g of lithium hydroxide will produce ?

cross multiply

grams of lithium bromide produced = 10 × 86.845/23.94784

grams of lithium bromide produced = 868.45/23.94784

grams of lithium bromide produced = 36.2642309286  ≈ 36.30 g

What happens when the vapor pressure of a liquid is equal to the external pressure? The liquid freezes The intermolecular forces
Makovka662 [10]

Answer:

The liquid boils.

Explanation:

Vapor pressure is simply defined as the pressure exerted on a substance (solid/liquid) by the vapor of the substance collected just at the top of the surface of the substance. In concise words, it is the pressure of Vapor that is in contact with its solid or liquid state.

For a liquid, it is the pressure of the Vapor gathering at the top of the surface of the liquid.

When this Vapor pressure matches the external pressure, the temperature stays constant and the molecules of the liquid all through the liquid can gain enough energy, rise to the surface of the liquid and break free in gaseous form; thereby, boiling.

The definition of boiling point basically explains that it is the point at which temperature stays constant, and the vapour pressure of the liquid matches the atmospheric/external pressure around the liquid and its liquid molecules change into vapor.

This is why liquids boil faster at higher altitudes; the atmospheric pressure at higher altitudes is reduced, hence, the temperature at which liquid boils at this high altitude is normally lower than its known boiling point temperature.

It is also why food cooks to a temperature higher than the boiling point of water in a pressure cooker/pot. The added pressure ensures that the cooking water boils at temperatures higher than its boiling point; thereby exposing the cooking ingredients to a higher temperature, leading to faster cooking.

Hence, it is obvious why boiling is the answer to this question.

A sunscreen preparation contains 2.50% benzyl salicylate by mass. If a tube contains 4.0 oz
antoniya [11.8K]

About 0.92 kg of benzyl salicylate would be needed in order to manufacture 325 tubes of sunscreen.

A tube contains 4.0 oz of the sunscreen and each one 2.5% benzyl salicylate.

         2.5% of 4.0 oz = 0.1 oz

Thus, each tube would need 0.1 oz of benzyl salicylate.

325 tubes of the sunscreen is needed and each one requires 0.1 oz of benzyl salicylate. Hence, total amount of benzyl salicylate needed would be:

    325 x 0.1 oz = 32.5 oz

From conversion:

16 oz = 1 lb

Hence,

32.5 oz = 32.5/16

                        = 2.03 lb

Also:

2.205 lb = 1 kg

2.03 lb = 2.03/2.205

             = 0.92 kg
