Answer:
Explanation:
crystallization The crystallization temperature of a brine is the temperature at which a solid phase begins to form, resulting in a mixture of solid particles and solution. These solids may be salt crystals or water crystals (ice). It is the point at which the minimumcrystallization temperature can be realized
The answer is A) Aluminum chloride - It does not have the prefix "tri-" since it is ionic.
Answer:
B. 3<4<1<2
Explanation:
Upon comparing all four equations, you would find that it is pretty much only the value of Kp that varies.
So we have to understand what Kp is and its relationship with tendency of completion.
Kp is the equilibrium constant calculated from the partial pressures of a reaction equation. It is used to express the relationship between product pressures and reactant pressures. It is a unitless number, although it relates the pressures.
So what is the significance?
If K is a large number, it means that the equilibrium concentration of the products is large. In this case, the reaction as written will proceed to the right (resulting in an increase in the concentration of products).
So what do we now?
We pretty much just have to arrange the equations in order of increasing K values.
Upon doing that, we are left with;
3) 2SO3 <---> 2SO2 +O2 Kp= 1.3x 10-5
4) 2NO2 <---> 2NO +O2 Kp=5.9 x 10-5
1) 2NOCl <---> 2NO +Cl2 Kp=1.7 x 10-2
2) N2O4 <--->2NO2 Kp= 1.5x 103
So the order is given as; 3<4<1<2
To determine how much water can form would depend on what the acetic acid is reacting with. However, a very common reaction of acetic acid that leads to the formation of water is the condensation that occurs during the esterification process. We can react acetic acid with an alcohol, such as methanol, and form the ester and water.
CH₃CO₂H + CH₃OH → CH₃CO₂CH₃ + H₂O
The mole ratio of water to acetic acid is 1:1. We can now use the mass of acetic acid to find the moles, which we can convert to moles of water:
5.10 g CH₃CO₂H / 60 g/mol = 0.085 mol CH₃CO₂H x 1 mol H₂O/1 mol CH₃CO₂H = 0.085 mol H₂O
0.085 mol H₂O x 18 g/mol = 1.53 g H₂O
In the reaction provided, assuming the reaction goes to completion, 5.10 g of acetic acid can form 1.53 g of water.
