Answer:
The answer is: CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Explanation:
Boiling point refers to the temperature at which the pressure exerted by the surrounding on the liquid is equal to the vapor pressure of the liquid. The boiling point increases as the molar mass of the substance increases.
Since the molar mass increases in the order:
CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Therefore, the order of increasing boiling point:
CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Answer:
H2SO4 + 2NaOH ==> Na2SO4 + 2H2O

C not sure 100 percent but my best guess
Loess, which can be carried by wind over long distances.
Answer:
1.43 (w/w %)
Explanation:
HCl reacts with NH3 as follows:
HCl + NH3 → NH4+ + Cl-
<em>1 mole of HCl reacts per mole of ammonia.</em>
Mass of NH3 is obtained as follows:
<em>Moles HCl:</em>
0.02999L * (0.1068mol / L) = 3.203x10-3 moles HCl = <em>Moles NH3</em>
<em>Mass NH3 in the aliquot:</em>
3.203x10-3 moles NH3 * (17.031g / mol) = 0.0545g.
Mass of sample + water = 22.225g + 75.815g = 98.04g
Dilution factor: 98.04g / 14.842g = 6.6056
That means mass of NH3 in the sample is:
0.0545g * 6.6056 = 0.36g NH3
Weight percent is:
0.36g NH3 / 25.225g * 100
<h3>1.43 (w/w %)</h3>
