Answer;
D, Xe (g)
Solution and explanation;
If 2g has a volume of 340ml.
Density is 1000/340*2 = 5.88g/litre.
-This rules out the two solids, choices 2) &3)
If 1 litre has mass 5.88g,
then 22.4 liters (volume at STP) has mass 5.88*22.4 = 131.8g/mol
molar mass Br2 = 80*2 = 160g/mol NO
molar mass Xe = 131.3g/mol = YES.
Answer is Xe
The answer to the question asked above is that in a Molecular Solid, the substance just dissolves into the solution when added to water but ionic solid does not.

Answer:
Final temperature = 28.0 degrees C.
Explanation:
heat absorbed = mass * specific heat * rise in temperature.
The specific heat of water is 4.186 J /g/C so we have the equation
209 = 10 * 4.186 * x where x is the temperature increase
41.86x = 209
= 5 degrees C.
The highest concentration of water would be found in the 5% solution. The concentration given above is percent of glucose, so the solution contain 5% of glucose and 95% of water. Comparing it to 10% of glucose solution which will have 10% glucose and 90% water, clearly, it is the 5% solution that has the highest amount of water in the solution. <span>Percentage
by a certain unit is the amount of that unit of a component in a mixture per 100 units of the
total mixture. </span>
