Density, Volume and Mass
3. A metal weighing 7.101 g is placed in a graduated cylinder containing 33.0 mL of water. The water
level rose to the 37.4 mL mark.
a) Calculate the density of the metal (in g/mL).
b) If you were to do this with an equal mass of aluminum (d = 2.7 g/mL), how high would the water rise?
The first one is the correct answer: <span>The potential energy of the products is greater than that of the reactants and the change in enthalpy is positive.<span> </span></span>
There are actually 4 factors. Temperature, pressure, rock type and time.
Answer:
<em>The Cloud of gas .</em>
Explanation:
<em>Once the pressure gets high enough, it begins to rival the strength of gravity and the collapse of the cloud slows down. Eventually, the cloud of gas becomes a protostar: an infant star that has not yet begun to fuse hydrogen in its core.</em>
The freezing point is mathematically given as
ft=-12.5C
<h3>What would be the freezing point ?</h3>
Question Parameters:
5.00 kg glycol, Ca(OH)2. [this is antifreeze] is added to your radiator. If your radiator contains 12.0 kg
The molar freezing point depression constant for water is 1.86 'C.kg/mole.
Generally the equation for the Freezing point is mathematically given as
ft=k f 
Therefore
0-ft=1.89*5000.62*1/12
ft=-12.5C
