The approximate molar concentration of several chemicals are given. Find the pH of each use the calculator and round to the nearest 10th if necessary. Here is the photo of the question

--- Oven Cleaner

--- Water

--- Blood

--- Vinegar

Step-by-step explanation:

The given molar concentration are:[Missing from the question]

Oven Cleaner: [h+] =

Water: [h+] =

Blood: [h+] =

Vinegar: [h+] =

Required

Determine the pH

pH is calculated using:

So, we have:

Oven Cleaner:

Using a calculator, we have:

Water:

Using a calculator, we have:

Blood:

Using a calculator, we have:

Vinegar:

Using a calculator, we have:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
