  • Instructions

    General Chemistry 10th Edition by Darrell D. Ebbing and Steven D. Gammon includes more than 1390 end-of-chapter problems plus ChemWork assignments and Thinkwell® lecture videos. Questions provide links to Watch It videos, and relevant textbook pages.

    Questions 1-5 are end-of-chapter problems enhanced with links to Read It and Watch It buttons.

    Read It - Relevant textbook pages

    Watch It - Watch Its include 5 to 7 minute mini-lectures from Thinkwell®. This demo assignment allows many submissions and allows you to try another version of the same question for practice wherever the problem has randomized values.

Assignment Submission

For this assignment, you submit answers by question parts. The number of submissions remaining for each question part only changes if you submit or change the answer.

Consider the following setup, which shows identical containers connected by a tube with a valve that is presently closed. The container on the left has 1.0 mol of H2 gas; the container on the right has 1.0 mol of O2.
(a) Which container has the greatest density of gas?
    

(b) Which container has molecules that are moving at a faster average molecular speed?
    

(c) Which container has more molecules?
    

(d) If the valve is opened, will the pressure in each of the containers change? If it does, how will it change (increase, decrease, or no change)?
    

(e) 1.0 mol of Ar is added to the system with the valve open. What fraction of the total pressure will be due to the H2?

A 24.6-mL volume of a hydrochloric acid solution reacts completely with a solid sample of magnesium carbonate, producing 177 mL of CO2 that is collected at 24.0°C and 738 torr total pressure. The reaction is given below.
2 HCl(aq) + MgCO3(s) → CO2(g) + H2O(l) + MgCl2(aq)
What is the molarity of the HCl solution?
WebAssign will check your answer for the correct number of significant figures.(No Response) M
