B) Compound
Answer:
The height of a column of ethanol is 13.1m
Explanation:
we begin by converting the density to SI unit= <u>0.789g/cm3* 1kg * </u>
<u>* </u>
cm * 1000g * 
= 789kg/m3
converting pressure to SI unit= 1 atm =101325 Pa
hence P= hdg
g= 9.81 m/s2
making h the subject of the formula
h= P/dg
h= 101325Pa/ 789kg/m3 * 9.81 m/s2
h= 13.1m
If 2500 grams of H2SO4 react with excess NH3 according to the illustration, the amount of ammonium sulfate that can be produced would be 3,370.92 grams. If only 3100 grams of ammonium sulfate were produced, the percentage yield would be 91.96%.
<h3>Stoichiometric calculations</h3>
From the equation of the reaction:
2NH3(aq) + H2SO4(aq) → (NH4)2SO4(aq)
The mole ratio of H2SO4 and (NH4)2SO4 is 1:1
Mole of 2500 grams H2SO4 = 2500/98 = 25.51 moles
Equivalent mole of (NH4)2SO4 = 25.51 moles
Mass of 25.51 moles (NH4)2SO4 = 25.51 x 132.14 = 3,370.92 grams
If 3100 g of (NH4)2SO4 were actually produced, the percentage yield would be:
Percent yield = 3100/3370.92 x 100 = 91.96%

Answer:
A: Object A will move in the up direction. But not object B
Explanation:
It will move in the up direction because object A has an unbalanced force. For the up direction there, it is 6 newtons and for the bottom direction, it is 2 newtons. For the right and left direction, both of them are 3 newtons. So object A will move in the up direction because it has the most newtons(which is 6).
For Object B, it is unbalanced too. But object B will move to the right because it is 2 newtons there and there is one newton on the left. Furthermore, the up and down directions are 3 newtons. So they are balanced and will cancel out. Therefore, object A will move in the right direction because it has the most newtons(which is 3).
So the final answer is object A. Hope it helped!
