the easy way to think about it is that by dividing by 10^3 you are actually multipling by 1/10^3 which you can write as 10^-3 and the negative means that the decimal place moves to the left. so we move the decimal places (which is to the right of the 4 in the number above) 3 places to the left giving us: 6.714
(7/11l=0.636363636363...........
After two digits it repeats , meaning 63 are the two numbers repeated over and over.
Answer:
y = 1/2x + 6
Step-by-step explanation:
y = 1/2x + b
5 = 1/2(-2) + b
5 = -1 + b
6 = b
Answer: the fraction form is 331/500
Step-by-step explanation:
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.
