Hello,
In case, for the boiling point raise we can write:
Whereas T2 accounts for the boiling point of the solution which is 101.286 °C, T1 the volume of pure water which is 100.000 °C, i the van't Hoff factor that for this problem is 1 due to the solute's non-volatility, m the molality of the solute and Kb the boiling point constant that is 0.512 °C/m. In such a way, the change in the temperature is:
The molality is computed from the boiling point raise:
The moles are computed by multiplying the molality by the kilograms of water as the solvent (0.02002g):
And the molecular mass by dividing the mass of the solute by its moles:
Best regards.
That's false. A melting point is hot/warm, while the freezing point is cold.
Answer is A
Because Trees store carbon and make it oxygen
It should be a 3 because there are 6 oxygens and to balance the equation you need to balance the reactants side so you put a 3 so the products are the same as the reactants
Answer:
What do you think causes some rock types to have higher densities than others? (Assuming there are no air pockets in the rock, the types of minerals will determine the density. Granite contains lots of quartz and feldspar - both fairly light minerals, whereas basalt and gabbro are made of heavier minerals.)
