Answer:
The answer to your question is: Molarity = 0.83
Explanation:
Data
5% by mass
Molarity = ?
density = 1.05 g/ml
Molecular weight (CH₃COOH) = 24 + 32 + 4 = 60 g
Process
- Percent by mass means 5 g of vinegar in 100 ml of solution
- Calculate the moles of vinegar in the solution
60 g of vinegar ------------ 1 mol
5 g of vinegar ----------- x
x = (5 x 1) / 60
x = 0.0833 mol of vinegar
Formula
Molarity = moles of vinegar / volume (liters)
Substitution
Molarity = 0.0833 / 0.1
Molarity = 0.83
Answer:
- when the decane is heated it vaporises/turns to a gas
- decane vapour/gas breaks down as it comes into contact with hot porous pot
- large molecules of decane produce smaller molecules, including ethene
Is the most stable resonance Lewis structure since the octet rule is obeyed and the negative formal charge is carried out by N (electronegativity: 3.04) the most electronegative atom compared to S (electronegativity: 2.58)
Answer:
It's size
Explanation:
The definition of a dwarf planet is "a celestial body that orbits the sun and has a spherical shape but is not large enough to disturb other objects from its orbit"
Essentially, "dwarf" is an adjective. Just like saying the colour distinguishes a purple planet...
Answer:
Dependant
Explanation:
Depending on the kind of substance you have (since ur answer of what substances was vauge) you would want to look at the molecular structure of the substances.
Understanding intermolecular bonds are key here (research this)
For example, Bromine is found as Br2 and only exerts London dispersion forces as there is no difference in polarity. And because this force is weaker, it has a lower boiling point
Another example being something like Hydrochloric acid (HCl). This is where Hydrogen acts as the positive atom while chlorine is the negative atom. This creates a stronger force and thus, a higher boiling point than Br2
Finally, there is Something like H2O where the force in play is Hydrogen bonding as Nitrogen, Oxygen, Fluorine where the bonds are strongest due to the electronegativity is at the greatest difference between these and Hydrogen. and thus having a higher boiling point.
So depending on the substance's bond, that will help determine the boiling point. If they fall under the same group, go based on the greatest difference in electronegativity.
I don't know if this is what you're looking for but, hope this helps. :)
