Answer:
There are 10⁻⁷ hydrogen ions in one-liter water
Step-by-step explanation:
Hi there!
a. If the pH = 7.0, then:
-log(H) = 7.0
multiply both sides of the equation by -1
log(H) = -7.0
Apply 10ˣ to both sides
10^(log (H)) = 10⁻⁷
(H) = 10⁻⁷
There are 10⁻⁷ hydrogen ions in one-liter water.
Why 10^(log (H)) = (H)?
Let´s consider this function:
y = 10^(log x)
(Apply log to both sides)
log y = log 10^(log x)
(Apply logarithmic property: log xᵃ = a · log x)
log y = log x · log 10
(log 10 = 1)
log y = log x
y = x
(since y = 10^(log x) and y = x):
10^(log x) = x
That´s why 10^(log (H)) = (H)
Answer:
1/18
Step-by-step explanation:
The probability of rolling a 1 is 1/6 because there are 6 numbers. You multiply that probability by the probability of getting a 2 or 3 which is 2/6 or 1/3 to get 1/18.
The amount I would receive for the bond when I sell it at the yield to maturity is $810.41.
<h3>How much would I receive for the bond?</h3>
In order to determine the amount I would receive for the bond, the present value of the bond has to be determined. Present value is the discounted cash flow.
Present value = $10000 / (1.0619)^3.5 = $810.41

The answer is 42
first change the numbers from scientific notations into numbers.
1.47*10^7= 14700000
3.5*10^5= 350000
now divide the number of sweets by the number of packets. the quotient is the answer
14700000/350000= 42
good luck
I would try to answer, but you didn’t put any options to choose from.
