Moles of Cu: 10 / 63.5 = 0.157 mol
Moles of I2: 10 / 254 = 0.039 mol
I2 is the limiting reactant, therefore theoretical yield of CuI (I) is 0.039 mol, equating to 0.039 * 190.5 = around
A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids.
Given:
Ammonia
Hydrochloric acid
To find:
The amount excess of reactant left over in ammonia.
Solution:
Ammonia reacts rapidly with hydrochloric acid to form Ammonium Chloride
Equation for the above statement is derived as:
One gram per mole of ammonia
Similarly for 6.91g of
One gram per mole of hydrochloric acid
Similarly for 4.61g of
From the above information we can say that h c l is a limiting reactant.
Limiting reactant is an element that consumes lesser product in a chemical reaction.
Thus the amount of excess reactant is calculated by using the following formula
Amount of excess reactant left over in
Result:
Amount of excess reactant left over ammonia
Reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population
To calculate percent errorsubtract the accepted value from the experimental value.Take the absolute value of step 1.Divide that answer by the accepted value.Multiply that answer by 100
so% error = [|(10.085 g/ 10 ml) - 0.9975| / 0.9975] x 100
% error = 1.1 %
