There is no reaction between the two.

Zn + MgCl₂ → n.r

This is guided by the activity series. In order for a single-replacement reaction to occur, the element can only replace one element in the compound if it is more active. Since Zn is less active than Mg, it is unable to replace Mg. Thus, there is no reaction.

A gas is confined in a 0.3m diameter cylinder by a piston, on which rests a weight. The mass of the piston is 85 kg. The local a
iris [78.8K]

Explanation:

Force applied on the gas will be as follows.

                   F_{gas} = F_{atm} + (m + M) g

As,   F = pressure × area. Hence, calculate the forces as follows.

                  F_{gas} = pressure × area

                         = 1.4 \times 10^{5} Pa \times \pi \times (\frac{0.3}{2})^{2}

                          = 1.979 \times 10^{4} N

                  F_{atm} = pressure × area

                            = 1.0133 \times 10^{5} \times \pi \times (\frac{0.3}{2})^{2}

                            = 1.432 \times 10^{4} N

      F_{gas} - F_{atm} = 5.47 \times 10^{3} N

Substituting the calculated values into the above formula as follows.

                F_{gas} = F_{atm} + (m + M) g

              F_{gas} - F_{atm} = (m + M) g

              5.47 \times 10^{3} N = (m + 85) \times 9.8    

              5.47 \times 10^{3} N = 9.8m + 833

                               m = 472.76 kg

Thus, we can conclude that the mass is 472.76 kg.
