Explanation:
This is because gas particles are free to move as they are not held in place by strong molecular forces while particles in a solid are
Answer is: t<span>he hot soup will lose heat and the ice water will gain heat.
</span><span>Heat spontaneously flows from a hotter to a colder body.
</span>The thermal radiation<span> is </span>electromagnetic radiation<span> generated by the </span>thermal motion<span> of </span>charged particles<span> in </span>matter (in this case from the hot soup to the cold water).
Given :
A certain compound contains 4.0 g of calcium and 7.1 g of chlorine.
Its relative molecular mass is 111.
To Find :
Its empirical and molecular formulas.
Solution :
Moles of calcium ,
.
Moles of chlorine ,
.
The ratio calcium and chlorine is 1 : 2 .
So , the empirical formula is
.
Now , molecular mass of
is :

So , 
Therefore , the molecular formula is also
.
Hence , this is the required solution .
Answer:
In order to keep propane a liquid at room temperature (70° F or 21° C), it has to be held in a tank at a pressure of about 850 kPa. ... Household metal tanks cannot withstand this pressure. In short, natural gas is not stored in household tanks because the symmetry of its molecule makes it hard to liquify.
Answer: increase
Explanation: as pressure is increased, equlilibrium shifts towards the side with less moles of gas.
