If 2500 grams of H2SO4 react with excess NH3 according to the illustration, the amount of ammonium sulfate that can be produced would be 3,370.92 grams. If only 3100 grams of ammonium sulfate were produced, the percentage yield would be 91.96%.
<h3>Stoichiometric calculations</h3>
From the equation of the reaction:
2NH3(aq) + H2SO4(aq) → (NH4)2SO4(aq)
The mole ratio of H2SO4 and (NH4)2SO4 is 1:1
Mole of 2500 grams H2SO4 = 2500/98 = 25.51 moles
Equivalent mole of (NH4)2SO4 = 25.51 moles
Mass of 25.51 moles (NH4)2SO4 = 25.51 x 132.14 = 3,370.92 grams
If 3100 g of (NH4)2SO4 were actually produced, the percentage yield would be:
Percent yield = 3100/3370.92 x 100 = 91.96%

Answer:
A. Close the drying agent container whenever it is not in active use.
C. Wrap the lid of the drying agent container with tape for storage.
Explanation:
Drying agents also known as desiccants are used in pharmaceutical, food and other manufacturing to keep substances dry. These drying agents are anhydrous and hygroscopic. The right usage of these products requires that they are always stored in an air-tight container.
When they are to be removed from a container containing a solvent, they are to be separated by filtration or decanting.
The answer is C :
It controls the entry and exit of substances.
Explanation:
A chemical property is defined as the property that brings changes in chemical composition of a substance.
For example, flammability, combustion, reactivity, electronegativity etc are allchemical properties.
On the other hand, a property that does not bring any change in chemical composition of a substance is known as a physical property.
For example, shape, size, mass, density etc are all physical properties.
Thus, we can conclude that these may all be classified as chemical properties of a substance.
