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:
16.791 grams
Explanation:
The density formula is:
Rearrange the formula for m, the mass. Multiply both sides of the equation by v.
The mass of the gold nugget can be found by multiplying the density and volume. The density is 19.3 grams per cubic centimeter and the volume is 0.87 cubic centimeters.
Substitute the values into the formula.
Multiply. Note that the cubic centimeters, or cm³ will cancel each other out.
The mass of the gold nugget is 16.791 grams.

some elements have their outer electrons more tightly bound than
others. Those who have less tightly bound electrons are more reactive.
After this it gets more complex in explaining why they are bound with
different strengths. </span>
So I haven’t got time to answer all of it for you but the id you look at the picture of the periodic table I’ve added the top number in the red boxes are the groups and the period is how many elements down from the top it is (remember that the hydrogen and helium make up period ONE) so remember to include them when counting the elements as you go down the table
