First, calculate the amount fo Na2O that should be produced with the given amount of sodium using proper dimensional analysis and the balanced chemical reaction,
theoretical amount of Na2O = (54.1 g of Na)(1 mol Na/23 g Na)(2 mos Na2O/4 mols Na)(62 g Na2O/ 1mol Na2O)
theoretical amount of Na2O = 72.9 g of Na2O
Calculation of percent yield,
% yield = (61.8 g Na2O) / (72.9 g of Na2O) x 100%
% yield = 84.75%
Answer: 84.75%
Answer:
The 2 beakers of water will have different boiling points because the boiling point of water is a physical property and the property is independent of the amount of water.
Explanation:
Got 100 on my test
D) 60°C
Explanation:
The molecules of Nitrogen gas will have the highest average kinetic energy when their temperature is the highest.
According the kinetic molecular theory, the temperature of gases is directly proportional to their average kinetic energy.
The higher the temperature, the more kinetic energy they possess.
To find out the highest temperature from the given options, we need to solve and express all the given options in a single unit of temperature.
K = 273 + °C
Let us convert all to Kelvin;
-40°C;
K = 273 + (-40) = 233K
60°C;
K = 273 + 60 = 333K
We can see that 60°C has the highest temperature in kelvin and this will furnish the gas with the greatest average kinetic energy.

ºC = K - 273
ºC = 96 - 273
= -177ºC
answer A
hope this helps!
