Answer:
Answer is D, simplify the expression and solve.
A solution with a pH of 11 has a [H+] of 
Option B is correct option.
Step-by-step explanation:
A solution with a pH of 11 has a [H+] of= ?
pH=?
Concentration of H+ [H+]= ?
Formula used: ![pH=-log[H+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%2B%5D)
Putting values and finding [H+]
![pH=-log[H+]\\\,[H+]\,=10^{-pH}\\\,[H+]\,=10^{-11}\\\,[H+]\,=1.0\times 10^{-11}](https://tex.z-dn.net/?f=pH%3D-log%5BH%2B%5D%5C%5C%5C%2C%5BH%2B%5D%5C%2C%3D10%5E%7B-pH%7D%5C%5C%5C%2C%5BH%2B%5D%5C%2C%3D10%5E%7B-11%7D%5C%5C%5C%2C%5BH%2B%5D%5C%2C%3D1.0%5Ctimes%2010%5E%7B-11%7D)
So, A solution with a pH of 11 has a [H+] of
Option B is correct option.
¹¹/48 of the full cup
Step-by-step explanation:
We add the two fraction first to determine the total ratio
¹/4 + ²/3 = ¹¹/12
She uses ¼ cup grape juice for ¹¹/12 cup full of diluted grape juice
Therefore;
¼ : ¹¹/12
How How much grape juice does Sarah use for each full cup of water, i.e ¹²/12
? (x) : ¹²/12
We cross multiply the ratios;
¹²/12 * ¼ = ¹¹/12 * x
³/12 = ¹¹/12 x
³/12 * ¹²/11 = x
¹¹/48 = x

P.S this was epert verified
Step-by-step explanation:
given Tony can type at a constant rate of 110 words every 2 minutes.This means tony can type 55 words in every minute.
A- Tony can type W words in T minutes. W*T=M (M=Minutes Tony typed)
B- Tony can type 1100 words in 20 minutes. as 55*20=1100.
C- Yes, Tony can type the essay. Why: because in this equation w=55 and t=30 minutes so t*w=30*55=1650 so yes, Tony can write the essay.
