The equation for the pH of a substance is pH = –log[H+], where H+ is the concentration of hydrogen ions. Which equation models t
Zanzabum

Answer:  [H+] = 10^-7.2

Step-by-step explanation:

Given that the PH of the solution = 7.2

Using the formula pH = –log[H+]. To get the H+ concentration from the pH, raise both sides by the base of 10. Then we have

10^ -pH = H+. with pH of 7.2,

Thus the answer to this problem is

[H+] = 10^-7.2

Do you think Apple will eventually meet their goal of becoming a replacement for a physical wallet? Why or why not?
Simora [160]

Answer:

No

Step-by-step explanation:

This would be more of an opinion and not a fact, but I see it as very unlikely that they will be able to accomplish this goal. Mainly due to human psychology. Most individuals want to be able to physically hold their money as well as being able to physically exchange their money for the goods that they need since physical cash is accepted worldwide. Another main reason is that individual's want to know that their money is theirs and that no bank or corporation can withhold their hard earned cash.

(Q5) Decide if the function is an exponential function. If it is, state the initial value and the base. y=3.1^x
ycow [4]

Answer:

D

Step-by-step explanation:

Exponential equation takes the form  y=ab^x  where

a is the initial value ( a ≠ 0), and

b is the base ( b ≠ 1)

The equation given can be written as  y=3.1^x\\y=1*3.1^x. Thus, it is an exponential equation.

So a = 1 and b = 3.1

Thus we can say that the initial value = 1 and the base is 3.3
