212 degrees Fahrenheit is equivalent to 100 degrees Celsius.
Answer:
a) Mass = 3.9 g
b) Mass = 0.395 g
Explanation:
Density is related to the mass and volume of a substance by the relation:
a) Given:
Volume = 4.00cm3
Density = 0.97 g/cm3
Based on equation (1)
b) Given:
Volume = 125 ml
Density = 3.16 g/L
1 ml = 0.001 L
Therefore, 125 ml = 0.125 L
Based on equation (1)
Answer:
True
Explanation:
It's true because the pH is a measure of how basic or acid a solution is. In an acidic medium, the pH scales goes from 0 to 7. While in a basic medium goes from 7 to 14. The lower the pH value of the most acid the solution is.
1. The expression pH = -log(molar concentration of hydronium) allow to calculate the pH of a solution.
2. On the other hand, the expression pOH = -log(molar concentration of hydroxide) allow to determine the pOH of a solution.
The values of pH and pOH always obey the following expression:
pH + pOH = 14
Thus if for instance the pH becomes smaller the pOH must become bigger in order to fulfill the equation. Which means that the concentration of hydronium ions is greater than the hydroxide concentration.
For example, in an acidic medium:
if pH= 3, pOH= 11
In this case the molar concentration of hydronium is 0,001M. And the molar concentration of hydroxide ions is just 0,00000000001M.
Answer:
The answer to your question is organic or non polar compound.
Explanation:
Acetone is an organic compound then it's organic and one characteristic of these compounds is that they are non polar.
Water, aqueous hydrochloric acid and aqueous sodium chloride are inorganic and they are polar, they dissolve compounds similar to them, inorganic and polar compounds.
Answer: Option (B) is the correct answer.
Explanation:
A molecules that will have more number of hydrogen bonding will has highest boiling point because to break the hydrogen bonds high heat needs to be provided.
So, in the molecule 
there is presence of two alcoholic groups. Hence, it will have strongest hydrogen bonding as compared to the rest of molecules.
In the molecule 
there will be hydrogen bonding and dipole-dipole interactions. Hence, it boiling point will be slightly less than .
In the molecule 
, there will be only hydrogen bonding. Hence, its boiling point is less than .
In the molecule 
, there is no hydrogen bonding but there will be only dipole-dipole interactions. Hence, its boiling point will be the least.
Therefore, we can conclude that increasing order of boiling point will be as follows.
< < <
