Explanation:
The problem deals with a phase transition from solid to liquid. To the left we have ice and to the right we have liquid water.
For such change to take place, the process of melting must occur. During melting, a solid changes state from solid to liquid by taking energy from the environment.
- In solid state, the molecules of the water are in a fixed state about their fixed lattice.
- As the solid ice gains energy from the environment, it begins to melt.
- Energy increase causes the molecules of the water to start flowing to form a liquid.
The % yield if 200g of chlorine react with excess Potassium bromide to produce 410g of bromine is calculated as below
% yield = actual yield/theoretical yield x100
the actual yield = 410 grams
calculate the theoretical yield
by first calculate the moles of chlorine used
mole= mass/molar mass
molar mass of Cl2 = 35.5 x2= 71 g/mol
moles= 200g/71g/mol = 2.82 moles
cl2 +2 KBr = 2KCl +Br2
by use of mole ratio between Cl2 to Br2 which is 1:1 the moles of Br2 is also = 2.82 moles
theoretical mass = moles x molar mass
molar mass of Br2= 79.9 x2= 159.8 g/mol
moles= 2.82g x 159.8 g/mol = 450.64 grams
% yield is therefore = 410g/450.64 x100 = 90.98 %
