Answer:
hydrogen ion increases
Step-by-step explanation:
as the pH value decreases, the molecule becomes more acidic in nature. and a solution can be termed base when it contains OH-, and an acid when it contains a H+ ion.
the now formed solution will have attained 9 more H+ ions
Answer:
14
Step-by-step explanation:
aₙ = a₁ + (n-1)*d
59 = 2 + (20-1) * d
59 = 2 + 19d
19d = 59-2 = 57
d = 3
5th term: a₅ = 2 + 4 * 3 = 14
Answer: 2 independent sample test of proportions
Step-by-step explanation:
The teo independent sample test of proportion is also referred to as the two proportion z-test and it simply allows the researcher to compare the two proportions in order to ascertain if they're the same or not.
In this case, the null hypothesis will be that that the proportions given in the research are the same while the alternate hypothesis will be that there is a difference between the proportions given.
As we can see from the above the pattern is:
-In ascending order.
-A value of 100 is added to each new number.
The rest of the pattern will be:
3865+100. 3865+100×2. 3865+100×3
Therefore,the answer is: 3965. 4065. 4165.
