Balance the following:
Reactants Products
B2+ _W2->BW3

B2 + 3W2 ---> 2BW3

Explanation:

You have 2 B on the right and 1 B on the left to balance out B, you need to add 2 wich gives you 6 W on the left and 2 W on the right. To baance W on both sides you add a 3 to the W on the right which gives you 6  W on both sides.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
