The answer is B. bases measure below seven
think of it like this 7 is neutral going down from seven it rises in acidity and going up from seven increases in alkalinity
Answer:
17 mg/ml.
Explanation:
Since NaOH was titrated against Citric acid in the grape fruit, therefore
Converting g to mg,
0.1698 g * 1000 mg/1 g
= 169.8 mg
Volume of grapefruit juice = 10 ml
Mass of Citric acid in ml of juice = 169.8/10
= 17 mg/ml.
Q = mC∆T
<span>where: </span>
<span>q = heat </span>
<span>m = mass of substance = 35.0 grams </span>
<span>C = 0.385 J/g*C </span>
<span>∆T = change in temperature = 65C - 20C = 45C </span>
<span>q = (35.0 g)*(0.385 J/g*C)*(45C) = 606 J </span>
The proper definition would be B. A mixture that can be separated.
I'm pretty sure it's called alkenes or alkylnes
