Answer:
v2= 5.404L
Explanation:
using Boyle's law
p1 x v1 = p2 x v2
101.325 x 4.31 = 80.8 x v2
v2= (101.325 x 4.31)\80.8
v2= 5.404L
Answer:
Zinc is Zn and Magnesium is Mg
The second approach is correct. The other two approaches are not correct because they are incomplete; first approach would have been right IF the 6.0 ppm was MEASURED in hexane. Third approach cannot be right since it calculates moles and grams but not L.
Answer:
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given:
75 % is decomposed which means that 0.75 of is decomposed. So,
= 1 - 0.75 = 0.25
t = 60 min
k = 0.023 min⁻¹
Considering the expression for half life as:-
Where, k is rate constant
So,
