The process J is called deposition. Using water is an example; write an equation that represents the process of deposition.​

Answers

Answer 1
Answer:

In chemistry and phase equilibria, phase transition is a common phenomenon. There are many terms related to the phase transition. The process deposition is a physical process. This process is the opposite of sublimation.

Deposition is a phase transfer or phase transition process in which a substance in the gaseous state changes directly to the solid state. Freezing of air is an example of deposition in which the water vapour directly changes to ice.

Here the gaseous state converts into solid state without being in the liquid state.

An example is:

CO₂ (g) → CO₂ (s)

Maki uses 20 gallons of a solution with an unknown ethanol concentration and 60 gallons of a 12% ethanol solution to make 80 gallons of a 10% solution. What is the value of x, the concentration of the unknown ethanol solution?. a. 0.02.
b. 0.04.
c. 0.05.
d. 0.08

Answers

This question is based on the concept of percentage by mass. Therefore the value of x, concentration of unknown ethanol solution is 4% when 20 gallons of a known solution is used. Option b is correct option

What is percentage by mass?

Mass percentage represents the the percentage of each element that is making a particular compound. Mass percentage does not have any unit as numerator and denominator contains the same unit.

Mathematically,

Percentage of mass = (component’s mass ÷ total mass) x 100%

According to the question the equation can be written as:

20× (x÷ 100) + 60×0.12 = 80× 0.10

x÷5 + 7.2 = 8

x÷ 5 = 0.8

x = 4%

concentration of unknown solution = 4%

Therefore, the value of x, concentration of unknown ethanol solution is 4% when 20 gallons of a solution is used. Option b is correct option
