Answer:3.5 days is awfully precise and waxing gibbous is awfully vague.Let’s just make sure we understand our terminology. Waxing means getting fatter and gibbous means fat. A waxing gibbous moon lasts for approximately 7 days from the first quarter phase right up to the full moon phase.By 3.5 days I’m assuming you mean half a week and simplifying the lunar phases to 28 days exactly.So we have:Day 0 New moon.Day 7 First quarter.Day 14 Full moon.Day 21 Third quarter.Day 28 New Moon.Between day 0 - 7 we have the waxing crescent phase.Between day 7–14 we have the waxing gibbous phase.Between day 14–21 we have the waning gibbous phase.Between day 21–28 we have the waning crescent phase.So 3.5 days from day 7 would take us to day 10.5 which would still leave us in the waxing gibbous phase. 3.5 days after day 10.5 would take us to the full moon or over into the waning gibbous phase since the full moon lasts only an instant.

Explanation:
Below is the equation of the chemical reaction:
CH3COOH (aq) + NaOH (aq) ----------> CH3COONa (aq) + H2O (l)
The mole ratio of acid and base in the balanced equation is:
Ma = 1, Mb = 1
Cb = 0.1001 mole/Kg
Ca = ???
Va = 10 grams
Vb = 131.44 - 48.11 = 83.33 grams
From the acid-base mole ration formula



The number of moles of acetic acid in the sample = 
Therefore 0.008341333 moles of acetic acid are in the sample.
Answer:
25 mL of the 10% solution.
Explanation:
<em>Clayton will mix x milliliters of a 10%, percent by mass saline solution with y milliliters of a 20%, percent by mass saline solution in order to create an 18%, percent by mass saline solution.</em> This can be described with the following equation:
0.1 x + 0.2 y = 0.18 (x + y) [1]
<em>If Clayton uses 100 milliliters of the 20%, percent by mass saline solution, how many milliliters of the 10%, percent by mass saline solution must he use?</em>
If y = 100 mL, what should be the value of x?
Let's solve [1] for "x" and replace with the value of "y".
0.1 x + 0.2 y = 0.18 (x + y)
0.1 x + 0.2 y = 0.18 x + 0.18 y
0.02 y = 0.08 x
x = 0.25 y = 0.25 × 100 mL = 25 mL
