gas to liquid

Explanation:

The change of state indicated by this analogy is from gas to liquid.

Cylinder to the left is filled with gases

Cylinder to the right is made up of liquid.

  • Gases occupy the volumes of containers they are introduced into.
  • They are random and possess a high kinetic energy.
  • Liquids have definite volume and flow with one another.
  • The gases in A are dispersed and in random motion.
  • This phase change is called condensation

The reaction of 60.0 g of aluminum oxide with 30.0 g of carbon produced CO gas and 22.5 g of aluminum metal. What is the percent
natulia [17]

Answer:

The answer to your question is: 70.8%

Explanation:

Data

Al₂O₃ = 60 g

C = 30 g

CO = gas

Al = 22.5 g

MW Al₂O₃ = 102 g

MW C = 12 g

MW Al = 54 g

Reaction

                 Al₂O₃    +     3C     ⇒       3 CO    +    2 Al

Limiting reactant

                            102 g of Al₂O₃  -------------- 54 g Al

                             60 g                 --------------   x

                             x = 31.8 g

                            36 g of C ------------------ 54 g of Al

                            30 g of C ------------------  x

                            x = 45 g of Al

Limiting reactant = Al₂O₃

Percent yield = \frac{22.5}{31.8} x 100

Percent yield = 70.75 %

How many grams of nh3 can be produced from 3.72 mol of n2 and excess h2.
olganol [36]
N₂       + 3H₂ ⇒ 2NH₃
1mol       :         2mol
3,72mol  :         7,44mol

n = 7,44mol
M = 17g/mol

m = n * M = 7,44mol * 17g/mol = 126,48g
