Property of water:
Due to the water's ability to stick together (Cohesion), droplets form instead of being spread evenly.
The strong cohesion between water molecules:
- Cohesion is defined as the firm attraction between molecules of the same type.
- This characteristic of water is due to hydrogen.
- Water molecules are maintained intact by the strong connections that hydrogen forms with one another.
- Since hydrogen bonds are more attracted to one another than to the wax surface, they tend to bead when sprayed on it.
- Additionally, the surface tension of water is very strong. This indicates that the molecules on the water's surface are not being drawn in by other molecules in the water's interior due to comparable molecules surrounding them on all sides.
- These molecules tightly attach to one another while only slightly adhering to the other medium. These water drops are rounded due to surface tension, which allows them to cover the least amount of surface area.

Answer:
7.37. Oxygen for First Responders In self-contained breathing devices used by first responders, potassium superoxide, KO9, reacts with exhaled carbon dioxide to produce potassium carbonate and oxygen: 4 KO2s) 2 CO2g)2 K9CO3(s)+3 O2(g) How much O9 could be produced from 85g KOg?
<span>3 AgNO3 + FeCl3 = Fe(NO3)3 + 3 AgCl
moles AgNO3 = 18.0 g/ 169.87 g/mol=0.106
moles FeCl3 required = 0.106/3=0.0353
mass FeCl3 = 162.206 g/mol x 0.353 mol=5.73 g
mass FeCl3 in excess = 32.4 - 5.73 =26.7 g.
26.7 gram of excess reactant remain after the reaction is over</span>
Answer:
Explanation:
Hello,
In this case, for the equilibrium condition, the equilibrium constant is defined via the law of mass action, which states that the division between the concentrations of the products over the concentration of the reactants at equilibrium equals the equilibrium constant, for the given reaction:
The suitable equilibrium constant turns out:
Or in terms of the initial equilibrium constant:
Since the second reaction is a doubled version of the first one.
Best regards.
