A student experimentally determines the gas law constant, R, by reacting a small piece of magnesium with excess hydrochloric acid and then collecting the hydrogen gas over water in a eudiometer. Based L-atm on experimentally collected data, the student calculates R to equal 0.0832 mol·K L-atm Ideal gas law constant from literature: 0.08206 mol·K (a) Determine the percent error for the student's R-value. Percent error = % (b) For the statements below, identify the possible source(s) of error for this student's trial. The student notices a large air bubble in the eudiometer after collecting the hydrogen gas, but does not dislodge it. The student does not clean the zinc metal with sand paper. The student does not equilibrate the water levels within the eudiometer and the beaker at the end of the reaction. The water level in the eudiometer is 1-inch above the water level in the beaker. The student uses the barometric pressure for the lab to calculate R.

You have substance X which is very flammable and substance Y which is very combustible in your garage in containers right in front of where you park your car. It is a hot July afternoon, 119Fand you just come home from work where your car was parked outside in the sun for 8 hrs and you were running the air conditioning the entire way home (hence, the car is very hot and is giving off a lot of heat). Which substance would you be more worried about and why ?
When two cotton plugs, one moistened with ammonia and the other with hydrochloric acid, are simultaneously inserted into opposite ends of a glass tube that is 87.0 cm long, a white ring of NH4Cl forms where gaseous NH3 and gaseous HCl first come into contact.NH3(g) + HCl(g) ⟶ NH4 Cl(s)At approximately what distance from the ammonia moistened plug does this occur?
7. A methanol powered car produces CO₂ when it runs. Does that mean it is contributing to global warming? (A) No, if the methanol was produced from recently living biomass (B) Yes, if the methanol was produced from recently living biomass (C) Yes, if the methanol was produced from solar power (D) No, if the methanol was produced from natural gas. 8. The density of compressed natural gas is 60 grams per liter. If a car were powered by an engine that burned natural gas (similar to a gasoline engine), how large a compressed natural gas tank would it need to have the same range as a standard gasoline car? (A) about 3 times bigger than a standard car's gasoline tank (B) about the same as a standard car's gasoline tank (C) about 20 times bigger than a standard car's gasoline tank (D) about 10 times bigger than a standard car's gasoline tank
