Answer:
A is your answer.
Explanation:
This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
<u>Answer:</u> 0.5 moles of 
are produced in the reaction
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass.
The equation used is:
......(1)
Given mass of 
= 113.6 g
Molar mass of = 79.5 g/mol
Plugging values in equation 1:
For the given chemical reaction:
By the stoichiometry of the reaction:
If 3 moles of produces 1 mole of
So, 1.43 moles of will produce = 
of
Hence, 0.5 moles of are produced in the reaction
As I am reading the problem,i can tell the question gives you two temperatures, two pressures, one volume and asking for the other. this should be an indication that you need to use the following gas formula
P1V1/T1= P2V2/T2
P1= 2.0 atm
V2= 4.0 L
T1= 27= 300 K
P2= 8.0 atm
V2= ?
T2= 327= 600 k
let's plug in the values into the formula
(2.0 x 4.0)/ 300= (8.0 x V2)/ 600 K
V2= 2.0 Liters
answer is D
The correct answer is d)all of above
examples for a are tyrosine for b lysine and for c isoleucine
