If you were going to graphically determine the enthalpy of vaporization, δhvap, for this liquid, what points would you plot

It depends on what type of graph you have. The easiest would be using a H-T diagram. Enthalpy of vaporization is the physical change from liquid to vapor. It occurs at a constant pressure and a constant temperature. As shown in the picture, 1 point is drawn on the subcooled liquid, and another point of the saturated vapor isothermal line. Now, the difference between those two points is the value for the enthalpy of vaporization of water.

Is it possible to tell if an acid or base is strong or weak just by looking at its chemical formula?
Gre4nikov [31]
It is.

An acid will be strong when its conjugated base is highly stable, and vice-versa.

That can occur for instance through electronic delocalization.

What happens to the reaction c2h6 + 137 kj c2h4+h2 when the temperature of the reaction is increased?
Softa [21]
Answer is: at higher temperatures reaction will go to the right (forward), more products (C₂H₄ and H₂) will be produce, because this is endothermic reaction (ΔH<span> is positive, </span>energy is consumed) and according Le Chatelier's principle <span>heat is included as a reactant. </span> .

Hello!

My argument: Which is better a Ps4 or an Xbox 1


The Ps4 is a better all-round console. The PS4 costs $100 less but has less games than the Xbox 1. The Xbox 1 now came up with dual compatible games. This means that certain games can now run on the Xbox 1 and the Xbox 360. The overall winner is really undetermined. The controller for Xbox has more quicker response time and is specifically built to be an extremely comfortable in your hands. Unlike the PS4 which their controller is built for nothing they really didn't do anything to theirs. Although the console comparisons are the same. The hard drive for the Xbox is non- removable meaning that if you want the hard drive. you would have to break the Xbox to get it . Unlike the Ps4 when you can take it out easily and switch it with any console and still have your data. I am an Xbox fan since for ever but I think that the two consoles are built the same.


Hope it helps!

Write the formula and calculate the molecular mass of
Reika [66]

The molecular formula is the sum of the atomic masses of all atoms in the molecule.

The formula of Soda Ash:

Na₂CO₃ is also known as Sodium Carbonate.

The molecular mass of Soda Ash is

(2×Na)+(1×C)+(3×O)=106g/mol

The formula of Baking Soda:

NaHCO₃ is also known as Sodium bicarbonate.

The molecular mass of Baking Soda is

(1×Na)+(1×H)+(1×C)+(3×O)=84g/mol

The formula of Lime Stone:

CaCO₃ is also known as Calcium carbonate.

The molecular mass of Lime Stone:

(1×Ca)+(1×H)+(1×C)+(3×O)=100g/mol

The formula of Ethanol:

C₂H₅OH is the formula of ethanol.

The molecular mass of Ethanol:

(2×C)+(6×H)+(1×O)=46g/mol
