Answer : The number of moles of 
and 
at equilibrium is, 1.75 mol and 0.87 mol respectively.
Explanation :
The given chemical reaction is:
Initial mol. 3.67 1.83 0
At eqm. (3.67-2x) (1.83-x) 2x
As we are given:
Number of moles of 
at equilibrium = 1.92
That means,
2x = 1.92
x = 0.96 mol
Number of moles of at equilibrium = (3.67-2x) = [3.67-2(0.96)] = 1.75 mol
Number of moles of at equilibrium = (1.83-x) = (1.83-0.96) = 0.87 mol
Thus, the number of moles of and at equilibrium is, 1.75 mol and 0.87 mol respectively.
<u>Answer:</u> The mass of a solute is 35 grams
<u>Explanation:</u>
To calculate the mass percentage of solute, we use the equation:
Mass percent of solute = 10 %
Mass of solution = 350 g
Putting values in above equation, we get:
Hence, the mass of a solute is 35 grams
The heat change is related to specific heat as
Heat change = mass of substance X specific heat X change in temperature
So if we are considering same amount of substance
and we are starting with the same temperature
the change in temperature will be inversely proportional to the specific heat
higher the specific heat lower the temperature change
Thus the change in temperature will be least for the substance with highest specific heat.
Answer: Hydrogen
As water is boiled, kinetic energy causes<span> the </span>hydrogen bonds to break<span> completely and allows water molecules to escape into the air as gas (steam or water vapor). When water freezes, water molecules form a crystalline structure maintained by </span>hydrogen bonding<span>. Solid water, or </span>ice<span>, is less dense than liquid water.</span>
A climograph is a dual-purpose graph, showing two different kinds of information. A bar graph shows how much precipitation a given place receives during a period of time. A line graph shows the temperature conditions for the same place during the same period of time.
