Answer:
Percent yield = 114.5%
Explanation:
Given data:
Calculated amount of product/ theoretical yield = 55 g
Actual amount of product after performing reaction = 63 g
Percent yield = ?
Solution:
Formula:
Percent yield = ( actual yield / theoretical yield )× 100
by putting values,
Percent yield = (63 g/ 55 g)× 100
Percent yield = 114.5%
Answer:
37
Explanation:
( 98.6 - 32 ) × 5(100c) ÷ 9(180f) = 37

The amount of current required to produce 75. 8 g of iron metal from a solution of aqueous iron (iii)chloride in 6. 75 hours is 168.4A.
The amount of Current required to deposit a metal can be find out by using The Law of Equivalence. It states that the number of gram equivalents of each reactant and product is equal in a given reaction.
It can be found using the formula,
m = Z I t
where, m = mass of metal deposited = 75.8g
Z = Equivalent mass / 96500 = 18.6 / 96500 = 0.0001
I is the current passed
t is the time taken = 75hour = 75 × 60 = 4500s
On subsituting in above formula,
75.8 = E I t / F
⇒ 75.8 = 0.0001 × I × 4500
⇒ I = 168.4 Ampere (A)
Hence, amount of current required to deposit a metal is 168.4A.

The pressure of a gas is the force that a gas exerts per unit area of the container.
Pressure is defined as force per unit area. Gas molecules are constantly colliding against the walls of the container. The pressure of the gas is the force the gas is exerting on its container.
Since temperature is defined as the average kinetic energy of the molecules of a gas then the higher the temperature, the faster the particles move.
The volume of a container refers the size if the container.
The pressure of a gas is inversely proportional to its volume according to Boyle's law. Thus implies that if the pressure of the gas goes up, the volume has to go down.
For a compound to be called an acid, it must contain H+ and H3O+ when dissolved in water.
For a compound to be called a base, the compound must dissolve in water to yield hydroxide ions.
