Mg(s) + 2 HCl (aq) _MGCL2 (Aq) + H2 (g) the total pressure of gas collected over water is 740.0 mmhg and the temperature is 21.5
Julli [10]

The pressure of hydrogen gas formed  is 720.8 mmHg.

<h3>What is Partial Pressure ?</h3>

The pressure exerted by a (specified) component in a mixture of gases.

We have to understand one thing that the Hydrogen, which is collected over water, will be mixed with water vapor.

This means that the total pressure of the mixture will have two components.

  • the partial pressure of Hydrogen
  • the vapor pressure of water at 21.5 C

The vapor pressure of water at that temperature is approximately

19.231 mmHg.

This means that

\rm P_{total} = P_{hydrogen}  + \; P_{water vapor}

740 = \rm P_{hydrogen} + 19.231

\rm P_{hydrogen} = 740-19.231

\rm P_{hydrogen} = 720.8 mmHg

Therefore the pressure of hydrogen gas formed  is 720.8 mmHg.

To know more about Partial Pressure

Cumyl chloride reacts with azide ion in water to form a mixture of an alcohol and an alkyl azide. Predict the effects of each ch
ryzh [129]

Answer:

(a). Increase in the rate of Reaction.

(b). Increase in the formation of the alcohol.

(c). rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(d).rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(e). rate of reaction increases because of carbocation.

Explanation:

Important thing to note is that this reaction proceed with an SN1 mechanism.

Therefore; the rate of reaction depends solely on the concentration of alkyl azide.

(a). The concentration of the alkyl chloride is increased: rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(b) The concentration of the azide ion is increased: the effect is that there will be an increase in the formation of more of the alcohol.

c) The alkyl bromide is used instead of the alkyl chloride: the effect is that there will be rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(d) The reaction is carried out in 1:1 acetone water instead of pure water: the effect is that there will be the effect is that there will be rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(e) The alkyl chloride shown below is used instead of cumyl chloride: rate of reaction increases because of carbocation.
