Compare 1.0 mol/L sodium hydroxide with 1.0 mol/L ammonia (written as ammonium hydroxide) by recreating similar diagrams of dissociation and concentration as those provided to you for the acid comparison. Assume ammonia dissociates only 1%. What would you expect to see if you tested the conductivity and pH of each? Why is there a difference in reactivity if there is 1 mole of acid in a given litre?

1)Name two reagents you could use to prove than unknown substance is a reducing agent.For Each reagent, give the colour change you would expect and explain this colour change.

2)Name two substances that can behave as both oxidising and reducing agents.

3)Suggest an alternative name for nitrogen monoxide (NO) using oxidation number.

A chemist is measuring the pressure of a gas at different temperatures

Temp(°C) =Pressure (atm)

-136 = 0.50

- 25 = 0.91

0= 1.00

100= 1.37

273 =2.00

Can you predict the temperature at which the pressure would equal 0? Explain how you came to your conclusion
