You should make a density trap, you get different liquids with different density's ( corn starch , water , alcohol , syrup) and pour them into a big vase and the different density's will sit on top of each other . the best thing to do is to use food coloring so that each level is a different color.
Answer:
Answer is explained in the explanation section below.
Explanation:
Note: This question is not complete and lacks necessary data to solve. However, I have found a similar question and I will be using its data to solve this question for the sake of understanding and concept.
Solution:
Equilibrium Reaction:
CaO(s) + H2O(g) -->Ca(OH)2(s)
We need to find the reaction quotient for this question:
Q =
Here, only the pressure of the gaseous reactant will be used and here H20 is the only reactant which is gaseous.
And we are given that, vapor pressure of water is = 0.106 mmHg
So,
Now, we need to convert it into atm
so, 1atm = 760 mmHg
0.106 mmHg = 0.106/760 atm
0.106 mmHg = 1.394 x
atm
Plugging in the values in the equation, we get:
Q =
Q = 
Q = 7173.60 
Answer:
Barium and Calcium
Explanation:
When heated with chlorine,
Both calcium and barium are able to form ionic bonds.
Hydrogen can only form bonds that are partial positive. It is not strong enough to be considered an ionic bond.
Silicon forms strong covalent with chlorine, called silicon tetrachloride. The structure is in diamond form which requires a lot of heat energy to break the bonds are way more than energy needed to break the bonds between calcium chloride.
Krypton is an inert element which does not form bonds with any elements under standard conditions
