Student A would be introducing more error. While student B is subtracting the actual filter paper used in the experiment, Student A is using the mass of a different filter paper, which may have a slightly different mass than the filter paper that was used. To avoid having to aacount for this, or introducing such an error, follow Student B in weighing the filter paper before adding the sand.

Determine the freezing point depression of 2 kg of water when 2 mol salt is added to it. The kf of water is 1.86 degrees C/M. Sh
Svet_ta [14]

Answer: The freezing point depression is 1.86^0C

Explanation:

Depression in freezing point is given by:

\Delta T_f=K_f\times m

\Delta T_f = Depression in freezing point

K_f = freezing point constant = 1.86^0C/m

m= molality = \frac{\text {moles of solute}}{\text {mass of solvent in kg}}=\frac{2mol}{2kg}=1m

\Delta T_f=1.86mol/kg^0C\times 1m  

\Delta T_f=1.86^0C  

Thus freezing point depression is 1.86^0C

Propane, the gas used in barbeque grills, is made of carbon and hydrogen. Will the atoms that make up propane form covalent bond
Masteriza [31]
Hydrocarbons are molecules that contain only carbon and hydrogen. Due to carbon's unique bonding patterns, hydrocarbons can have single, double, or triple bonds between the carbon atoms. The names of hydrocarbons with single bonds end in "-ane," those with double bonds end in "-ene," and those with triple bonds end in "-yne". The bonding of hydrocarbons allows them to form rings or chains.
