Question 4 L2.2
Boyle's law is

P. V1 = P2V2 A balloon has an initial volume of 355 L and an initial pressure of 234 kPa.

The volume is lowered to a final value of 227 L Use Boyle's Law to calculate the final pressure.
Round to two decimal points and do not use units.

Question 5
L2.3

The ideal gas law equation is

PV=nRT

How many moles of gas are in closed container with a pressure of 400 kpa, volume of 10L and a temperature of 450 K?

use 8.31 L * kpa/K * mol for R​

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.

Find the number of grams of hcl needed to react completely with .50 moles of magnesium.

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
