Answer:

12.44 g

Explanation:

2C4H10 + 13O2 = 8CO2 + 10H2O

n(C4H10) = m(C4H10)/M(C4H10) = 4.1 / 58g/mol = 0.0707 mol (excess).

n(O2) = m(O2)/M(O2) = 25.9 / 32g/mol = 0.809 mol (deficiency).

Since the ratio of O2 to octane is 13 : 2 we can divide 0.0707 by 2 to get 0.03535 and divide 0.809 by 13 to get 0.062.

mass of CO2 produced =

M = [0.0707 moles C4H10 x 8 moles CO2] / 2 moles C4H10 x 44 g CO2/mol

M = 0.5656/2 * 44

M = 0.2828 * 44

M = 12.44 of CO2

A 10-mL pipette delivers 9.99,10.01,9.97, and 10.8 mL in an experiment. Calculate the mean value and the average deviation from
Harman [31]
To find the mean of a number of numbers, First you add them up.
9.99 + 10.01 + 9.97 + 10.8 = 40.77
Then, you divide the result by how much numbers you have (in this case 4)
40.77 / 4 = 10.1925

So, the mean value is 10.1925.

The deviation is the difference between the number and the mean.
(number - mean = Average deviation)

So you get:
9.99 - mean = 9.99 - 10.1925 = -0.2025
10.01 - 10.1925 = -0.1825
9.97 - 10.1925 = -0.2225
10.8 - 10.1925 = 0.6075


Now to find the Average deviation, you do the same steps as finding the mean. Add them up, and divide by 4 (because there is 4 numbers)
P.S. Negative numbers become positive.

0.2025 + 0.1825 + 0.2225 +0.6075 = 1.215

1.215 / 4 = 0.30375

So, the Average Deviation is 0.30375

Hope this Helps :)

A 5.0L container is filled with H2 gas at STP. Predict what happens with the conditions of the gas change as described below (in
Amiraneli [1.4K]

Answer:

(a)  As temperature increases, the average kinetic energy increases

(b) If H₂ is replaced with N₂, there will be increase in average velocity

(c) An increase in temperature will cause increase in average velocity

(d) The increase in entropy as a result of an increase in temperature and average velocity will cause the kinetic energy to increase.

Explanation:

Given;

5.0L container filled with H₂ at stp

Part (a) What happens to average kinetic energy as temperature increases

As temperature increases, the average kinetic energy increases

Part(b) What happens to the average velocity if H₂ is replaced with N₂

Entropy is directly proportional to average velocity of gases and entropy increases with an increase in molecular mass.The molecular mass of nitrogen gas N₂ is greater than molecular mass of hydrogen gas H₂.

Thus, if H₂ is replaced with N₂, there will be increase in average velocity.

Part(c) What happens to the average velocity as temperature increases

Kinetic energy increases with an increase in temperature and average velocity.

An increase in temperature will cause increase in average velocity

Part (d) What happens to average kinetic energy if H₂ is replaced with N₂

The increase in entropy as a result of an increase in average velocity will cause the kinetic energy to increase.

Help please idk how to do this.

Single and Double Replacement reactions are exactly as they sound - they “replace” one or two components, depending on the type, with something else obtained in the reaction.

1. This is a double replacement reaction - see that the SO4 and the OH groups are trading what they’re paired with? OH starts paired with Aluminum, and ends up paired to the Hydrogen, and the SO4 starts with the Hydrogen, but ends up with the Aluminum. Two things being replaced - a double replacement reaction.

2. This is a single replacement reaction - Iron replaces the Hydrogen through the reaction, leaving the Hydrogen inbound afterwards; one thing being replaced - a single replacement reaction.

3. Like 1, this is a double replacement reaction - Fluorine and Oxygen trade partners. Two things being replaced - a double replacement reaction.

Number 4 isn’t complete, and I’m not sure about the goal of the practice problems, so I hope this helps enough to finish the work!
