Answer:
Therefore (2.30-0.03747)= 2.2625 M of HI remains from an initial concentration of 2.30 M after 4.5 hours.
Step-by-step explanation:
second order reaction: The rate of reaction proportional to the square of the concentration of reactant.
For second order reaction
K is rate constant = 1.6×10⁻³M⁻¹hr⁻¹
a = initial concentration of reactant = 2.30 M
a-x = concentration of reactant after t h
t = time = 4.5 h
Putting the values in the above equation,
Therefore (2.30-0.03747)= 2.2625 M of HI remains from an initial concentration of 2.30 M after 4.5 hours.
Answer:
b,c,d
Step-by-step explanation:
if its 43x, none of the point is true.
if its 4/3x:
a. Not true 4/3(1) + 5 = 6 1/3
b. True 4/3(6) + 5 = 13
c. True 4/3(21) + 5 = 33
d. True 4/3(99) + 5 = 137
Answer:
y = 2
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° = , then
sin45° = = = ( cross- multiply )
y = ( )² = 2
First you would do the square root of two which is about 1.4. now you would do 10+1.4 which is 11.4. now you do 4 divided by 11.4 which is about 0.4
Answer:
2 + y
Step-by-step explanation:
all you must do is add y to 2
