What mass of manganese(II) chloride must react with sulfuric acid to release 52.5 mL of hydrogen chloride gas at STP?

1 answer:

7 0

The balanced chemical reaction is written as:

MnCl2(s)+H2SO4(aq)→MnSO4(aq)+2HCl(g)

We are given the amount of hydrochloric acid to be produced in the reaction. This value will be the starting point for the calculations.We do as follows:

.0525 L HCl ( 1 mol / 22.4 L ) ( 1 mol MnCl2 / 2 mol HCl ) (125.84 g / 1 mol ) = 0.15 g MnCl2

Let’s assume that you put a balloon into the freezer. Initially,the balloon had 3.0liters of gas at a pressure of 400kPa and was

EastWind [94]

Here, we should use combined gas law which can be derived from combined gas law, “PV=nRT”. Rearranging, we can get PV/T=nR. Then we can set the two states in the problem together to get

P1V1/T1 = P2V2/T2

Then just plug in and solve algebraically.

Hope this helps

A runner runs for a distance of 350 yards and then runs for an additional 200 m. What is the total difference covered by the run

Rudiy27

Answer: 520.04 meters.

If you convert 350 yards to meters, you get 320.04.

320.04m + 200m = 520.04m.

Take off the .04 if necessary:)
