Calculate the Heat Released (KJ)in the Reaction of 3 $\rarr$ C₂H₆(g)
Given:
2C₂H₂(g)+ 5O₂(g)

question 82

Short Answer

Calculate the heat released (kJ)in the reaction of 3.50 g of acetylene (C₂H₂)and excess hydrogen gas to form ethane gas:
C₂H₂(g)+ 2H₂(g) $\rarr$ C₂H₆(g)
Given:
2C₂H₂(g)+ 5O₂(g) $\rarr$ 4CO₂(g)+ 2H₂O(g), $\Delta$ H = -2320 kJ/mol
2C₂H₆(g)+ 7O₂(g) $\rarr$ 4CO₂(g)+ 6H₂O(g), $\Delta$ H = -3040 kJ/mol
2H₂(g)+ O₂(g) $\rarr$ 2H₂O(g), $\Delta$ H = -572 kJ/mol

Definitions:

Population Mean

The average value of a set of characteristics within a specified entire population.

Standard Deviation

A measure of the amount of variation or dispersion in a set of values, indicating how spread out the data points are from the mean.

T-distribution

A probability distribution that is used to estimate population parameters when the sample size is small and/or when the population variance is unknown.

Test Statistic

A test statistic is a value calculated from sample data during a hypothesis test. It's compared to a critical value to decide whether to reject the null hypothesis.
