When 25.0 mL of a 0.610 M NaOH solution reacts with 20.0 mL of a 0.245 M H2SO4 solution

There is not enough H2SO4to consume all of the OH–.Therefore, H2SO4is the limiting reagent.There isexcess OH–(only 2 × 0.004900mol=0.009800mol of OH–is consumed, leaving0.01525– 0.009800molof OH–unreacted ).Therefore, the resulting solution is basic.4.

5. Whichoneof the following statements isFALSEregarding a gas initially at 300. K, 1.00 atmpressure, and 1.00 L volume?.A)Increasing the temperature to 900. K, at constant volume, increases the pressure to 3.00atm.B)Increasing the pressure to 2.00 atm, and volume to 3.00 L, leaves the gas at 1500. K.C)Increasing the temperature to 1200. K, at constant pressure, increases the volume to 4.00L.D)Decreasing the pressure to 0.500 atm, while increasing the volume to 4.00 L, leaves thegas at 600. K.E)There are 0.0406 moles of gas.

For an ideal gas,p V=n R TIn all of the processes, the amount of gas does not change (i.e. initial and finalnare the same)..=3.00 atmf/Vi==4.00 Lf/Vi=
