Answer:
In your example, sodium reacts with magnesium chloride in a single displacement reaction.
Vapour pressure is the pressure exerted by vapour molecules over a liquid surface.
The vapour pressure is a property
a) inter molecular forces: higher the inter molecular forces lower the vapour pressure, In this case we have taken same liquid (milk) hence in all case the inter molecular forces will be same.
b) Temperature: higher the temperature higher the kinetic energy of molecules and more the tendency of liquid molecules to convert to vapor phase.
The vapor pressure will be independent of the container being closes or open.
Thus vapor pressure will be high in Bowl B which is uncovered, and the milk is warmer than room temperature, as it has higher temperature than all other bowl of milk.
Answer: Measure 114 mL of the 1.75 M solution, and dilute it to 2.00 L.
Explanation:
The number of moles in the solution will remain same on dilution and thus according to Molarity Equation:
= molarity of first solution
= Volume of first solution
= molarity of second solution
= Volume of second solution
Thus 114 ml of 1.75 M solution is taken and the volume is diluted to 2.0 L to make 0.100 M solution.
A. The breeze blow from higher pressure over the water to the lower
