Refrigerant may be of four type such as R-22, R 410A, R- 290, R-417 A
The refrigerator R410A having standing pressure of about 260 psi whereas saction pressure of about 120 to 130 psi and discharge pressure of about 450 to 500 psi.
Refrigerant R-410 is a cooling machine consists of equipments and chillers for air conditioning purpose along with coolant gas. This refrigerant have high cooling capacity which consumes less power. The suction pressure is 118 psi and discharge pressure is 400 psi.
<u>Answer:</u> The limiting reagent in the reaction is bromine.
<u>Explanation:</u>
Limiting reagent is defined as the reagent which is completely consumed in the reaction and limits the formation of the product.
Excess reagent is defined as the reagent which is left behind after the completion of the reaction.
Given values:
Moles of iron = 10.0 moles
Moles of bromine = 12.0 moles
The chemical equation for the reaction of iron and bromine follows:
By the stoichiometry of the reaction:
If 3 moles of bromine reacts with 2 moles of iron
So, 12.0 moles of bromine will react with = of iron
As the given amount of iron is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.
Hence, bromine is considered a limiting reagent because it limits the formation of the product.
Thus, the limiting reagent in the reaction is bromine.
Since cells are hard to see the microscope helped them see. scientist were able to actually see cells in tissues placed under the microscope.
A combustion reaction takes place in the presence of O2 (g). The
products of a complete combustion reaction are CO2 (g) and H2O
(g).
Water is a compound consisting of 2 hydrogen atoms and 1 oxygen atom. The oxygen and the hydrogen are elements, while water is a compound.
