The theoretical yield of a reaction can be determined using its in the reaction between co and fe3o4, the theoretical yield in an experiment is calculated to be 47.2 g fe. when a careless chemistry student carries out the experiment, the actual yield is 26.5 g fe. calculate the percentage yield. chemical equation and the starting amounts of the reactants.

Explanation:

The expression for the calculation of the percentage yield for a chemical reaction is shown below as:-

Given , Values from the question:-

Theoretical yield = 47.2 g

Experimental yield = 26.5 g

Applying the values in the above expression as:-

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
