Atoms are made of subatomic particles known as protons, neutrons, and electrons.

(Small bonus: in order to mimic the technology of replicators like in star trek, you need to mess with protons, neutrons, and electrons) (pls dont report)

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 %

A lab technician mixed a 550 ml solution of water and alcohol. if 3% of the solution is alcohol, how many milliliters of alcoh

kupik [55]

The solution 550 ml total and first we will find the amount of alcohol. 3% = 0.03 550 ml x .03 = 16.5 ml alcohol
Then to find the amount of water used, we just have to subtract the amount of alcohol from the total volume
550 ml total - 16.5 ml alcohol = 533.5 ml water
