Answer:
1.668 S
Step-by-step explanation:
We are given that
Product
For first order reaction,
Rate constant=k=
Temperature=
We have to find the time taken by the reaction when concentration of A to decrease from 0.790 M to 0.230 M.
Substitute the values then we get
Hence, it would take 1.668 s for the concentration of A to decrease from 0.790 M to 0.230 M.
Answer:
We conclude that using the property of exponents, we need to multiply 10² to get 10⁴. Step-by-step explanation: Let 'x' be the number we need to multiply 10² by to get 10⁴. Therefore, we conclude that using the property of exponents, we need to multiply 10² to get 10⁴.
Answer:
r ≈ 22.44 ft
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius ), then
141 = 2πr ( divide both sides by 2π )
= r , that is
r ≈ 22.44 ft ( to the nearest hundredth )
Answer:
x=7
Step-by-step explanation:
6 - 6x = 5x – 9x - 8
Combine like terms
6-6x = -4x-8
Add 6x to each side
6-6x+6x =-4x-8+6x
6 = 2x-8
Add 8 to each side
6+8 = 2x-8+8
14 = 2x
Divide each side by 2
14/2 =2x/2
7 =x
Answer:
No
Step-by-step explanation:
A- full early flight atlanta to chicago
P(a)=0,8
B- full late night flightt
P(b)=0,7
A&b- both are full
P(a&b) probability that both flights are full
Suppose that they are independet, then we have:
P(a&b)=p(a)*p(b)=0,8*0,7=0,56.
So if they are independet then p(a&b)=0,56, and that is not true.
