<u>Answer:</u> The amount of energy required to raise the given amount of temperature is 6400 J
<u>Explanation:</u>
To calculate the heat absorbed by the lead, we use the equation:
where,
q = heat absorbed
m = mass of lead = 200 g
c = heat capacity of lead = 0.128 J/g°C
= change in temperature = 250°C
Putting values in above equation, we get:
Hence, the amount of energy required to raise the given amount of temperature is 6400 J
Answer:47.05% is the percent yield of nitrogen in the reaction.
Explanation:
heoretical yield of nitrogen gas = x
Moles of ammonia =
According to reaction,2 moles of ammonia gives 1 mol of nitrogen gas.
Then 2.3529 mol of ammonia will give:
of nitrogen gas
Mass of 1.1764 moles of nitrogen gas,x = 1.1764 mol × 28 g/mol=32.94 g
Experiential yield of nitrogen gas = 15.5 g
Percentage yield:
hope that help
47.05% is the percent yield of nitrogen in the reaction.
