How long will it take for the concentration to reach 0.0500 M?
This question is incomplete, the complete question is;
A general reaction written as A + 2B → C + 2D is studied and yields the following rate law: ∆A/∆t = k A².
The initial concentration is 1.000 M and t½=20.00 s.
How long will it take for the concentration to reach 0.0500 M
Answer:
it will take 380 seconds for the concentration to reach 0.0500 M
Step-by-step explanation:
Given that;
A + 2B → C + 2D
initial concentration A₀ = 1 M
half life t1/2 = 20sec
concentration after t time [A_t] = 0.0500 M
∆A/∆t = k A²
This is a second order chemical kinetics
for this order; t1/2 = 1 / [A]₀K
A₀ is initial concentration, K is rate constant, t1/2 is half life
so,
k = 1 / [A₀]t1/2
we substitute
K = 1 / 1.000 × 20
K = 0.05 mol⁻¹L/sec
for second reaction order
1/[A_t] = kt + 1/[A₀]
kt = 1/[A_t] - 1/[A₀]
we substitute
kt = 1/0.0500 - 1/1.000
kt = 20 - 1
kt = 19
substitute the value of k
0.05 × t = 19
t = 19 / 0.05
t = 380 sec
Therefore it will take 380 seconds for the concentration to reach 0.0500 M
1. Sally decided to go early Christmas shopping at a local Wal-Mart. There was
a Black Friday sale and she bought a TV that was originally $200. The TV
was marked down 25%. How much did Sally pay after it was marked down?
(1 point)
Answer:
150$
Step-by-step explanation:
In order to find the answer to this question you must find twenty-five percent of two-hundred.
50% of 100 = 50
100% of 100 = 100
100% of 200 = 200
50% of 200 = 100
25% of 200 = 150
= 150$

She charges her customers a call out fee of £35, plus £30 per hour.
How much should a customer be charged for wiring a house with 10 lightswitch?
Answer:
£395.
Step-by-step explanation:
Call out fee=35
30 per hour = 2 hour to be =60
but,12 minutes in hours= 12/60= 0.2
0.2 = 0.2*30 = 6
2 hours and 12 minutes would be charge as
30 + 6 = 36
36*10 = 360
call out fee + per hour = 35 + 360 + 395
A washer and dryer cost $1011 combined the washer cost $61 more than the dryer what is the cost of the dryer
Answer:
$475
Step-by-step explanation:
First, we need to subtract 61 from 1011 which given us 950. Then, we divide 950 by 2 to give us the cost of the dryer :)
950 ÷ 2 = 475
This means the cost of the washer is $536 (not relevant to the answer, but at least now you know :) )

Step-by-step explanation:
The slope of the line in the graph is,
⇒ m = 1
What is Equation of line?The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is,
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (- 1, 0) and (0, 1).
Now,
Since, The equation of line passes through the points (- 1, 0) and (0, 1).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - 0) / (0 - (-1))
m = 1 / 1
m = 1
Thus, The slope of the line in the graph is,
⇒ m = 1

Find the perimeter of the figure to the nearest hundredth, if a =9 and b=2.
Answer:
e. 23.14 m
Step-by-step explanation:
Perimeter of the figure = ½(perimeter of a circle) + 2(a) + b
= ½(πd) + 2(a) + b
Where,
d = 2 m
a = 9 m
b = 2 m
Plug in the values into the equation
Perimeter of the figure = ½(π*2) + 2(9) + 2
= π + 20
= 23.14 m (nearest hundredth)
Nick walked 3/4 of a mile in 12 minutes.How long would it take him to walk three miles at this pace
Answer:
48 minutes
Step-by-step explanation:
First do 3 divided by 3/4 and that gives you 4. Then multiply 4 by 12 and you get 48.
Answer:
45
Step-by-step explanation:
I love math, so this was fun! First, we need to know how long it would take him to walk 1 mile. We know it took 12 minutes to walk 3/4 of a mile, so we just need to figure out how long each quater is. For this problem, each quarter of a mile is 3 minutes, and so we just need to multiply that by 4. then, we know it would take him 15 mintues to walk a mile. Then, just multiply that by 3!

Find the coordinates of the point 7/10 of the way from A (-3,-5) to B (9.4)
Answer:
(-2/17, 5/17)
Step-by-step explanation:
Given the coordinates A (-3,-5) to B (9,4), we are to find the coordinate of the point cutting the line using the ratio 7:10
Using the midpoint formula;
M(X,Y) = {(ax1+bx2/a+b, (ay1+by2/a+b))
Given
x1 = -3, y1 = -5, x2 = 9, y2 = 4, a = 7 and b = 10
get the required coordinates;
X = ax1+bx2/a+b
X = 7(-3)+10(9)/7+10
X = -21+19/17
X = -2/17
Get the Y coordinate;
Y = ay1+by2/a+b
Y = 7(-5)+10(4)/7+10
Y = -35+40/17
Y = 5/17
Hence the required coordinate is (-2/17, 5/17)

Given the following table, find the equation that matches it.
Answer:
The equation that matches the table is y = -5x + 7 ⇒ C
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0)The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the lineFrom the given table
→ Choose any two points from the table
∵ Points (0, 7) and (1, 2) are in the table
∴ x1 = 0 and y1 = 7
∴ x2 = 1 and y2 = 2
→ Substitute them in the rule of the slope above
∵ m = [tex]\frac{2-7}{1-0}=\frac{-5}{1}[/tex]
∴ m = -5
→ Substitute it in the form of the equation above
∵ y = -5x + b
∵ b is the value of y at x = 0
∵ At x = 0, y = 7
∴ b = 7
∴ y = -5x + 7
∴ The equation that matches the table is y = -5x + 7

Answer:
can you space it plz
Step-by-step explanation:
Answer:
The correct answer is choice B.
Step-by-step explanation:
Monocots differ from the dicots In the structural features of the leaves, the stems, roots, and flowers. The differences start from the very beginning of the plant's life cycle: the seed. Monocots have one cotyledon, while dicots have two. When it comes to leaves, monocots have narrow leaves with the typical parallel leaf veins. Dicots have broad leaves with a network of netted leaf veins.
