If there is solution with nonvolatile solute (<span>substance that does not readily </span>evaporate<span> into a </span>gas) <span>only the pure vapor of the solvent is present above the solution and solute stays in solution and do not enters vapor above solution. This is because nonvolatile solute has slow rate of evaporation and low vapore pressure.
If solution has two volatile components, composition of the vapor depends on vapor pressures of the components according </span><span>Raoult's Law.</span>
It would most likely be a molecular compound. A molecular compound contains two or more nonmetals.
Answer:
Average atomic mass = 63.3896
Explanation:
Step 1: Find how much Cu-65 we have
1 - Amount of Cu-63 = Amount of Cu-65
1 - 0.6915 = Amount of Cu-65
Amount of Cu-65 = 0.305
Step 2: Find the average atomic mass of Cu
(0.6915 x 63) + (0.305 x 65) = <em>Average atomic mass</em>
(43.5645) + (19.825) = <em>Average atomic mass</em>
63.3895 = <em>Average atomic mass</em>
Therefore the average atomic mass of Cu is 63.3895 atomic mass units
Invertebrates affect the oxygen levels of compost and soil by reducing it.
<h3>How respiration works?</h3>
Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells.
Every living organism undergoes the process of cellular respiration and make use of oxygen molecules in the process.
This means that invertebrates will make use of the oxygen gas present in compost and the soil for respiration, hereby reducing it.

Answer:
The concentration of the chloride ion is 1.8 mM
Explanation:
Step 1: Data given
An aqueous solution contains 3.6 mM of total ions.
Step 2: The equation
NaCl(aq) → Na+(aq) + Cl-(aq) : two ions
Step 3: Calculate the concentration of the chloride ion
Two ions = 3.6 mM
Chloride ion = 3.6/2 mM= 1.8 mM
Sodium ion = 3.6/2 mM = 1.8 mM
The concentration of the sodium ions is 1.8 mM
The concentration of the chloride ion is 1.8 mM
The total concentration = 3.6 mM
