Answer:
Triple point
Explanation:
Yes, all three phases can exist in an equilibrium with one another at the triple point of a substance.
In thermodynamics, the triple point of a substance is defined as the point at which all three phases of substance co-exist together at a particular pressure and temperature.
for example, the triple point of mercury occurs at a temperature of −38.83440 °C and a pressure of 0.2 mPa.
And for water it is 0.01 °C and 611.73 pascals.
you will get some clear idea after seeing the graph.
And critical point as you see in the graph is end point of phase equilibrium curve, mainly liquid-vapor equilibrium
Moles of ZnSO4 = Mass/Mr
= 2/(65.4 + 32.1 + (16 x 4))
= 0.012383.... mol
Since there is no chemical equation provided, I will assume that the ratio of ZnSO4:Li2CO3 is 1:1
Therefore there are 0.012383 mil of Li2SO4 as well
So the mass would be Moles x Mr = 0.012383.... x ((6.9 x 2) +32.1 + (4x16))
= 1.360 g of Li2SO4 produced
Answer:
0.0125mol/dm³
Explanation:
Given parameters:
Mass of carbon dioxide = 0.22g
Volume of water = 400cm³
Unknown:
Concentration in mol/dm³ = ?
Solution:
Concentration is the amount of solute dissolved in a solvent.
The formula is expressed as;
Concentration =
Number of moles = ![\frac{mass}{molar mass}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bmolar%20mass%7D)
Molar mass of CO₂ = 12 + 3(16) = 44g/mol
Number of moles =
= 0.0005mol
Now,
1000cm³ = 1dm³
400cm³ =
= 0.4dm³
Insert the parameters and solve;
Concentration =
= 0.0125mol/dm³
