Answer:
D
Explanation:
I think they would design a airplane with this new metal first because they have to find the right balance for this new type of metal. They can't just sell a airplane with a new metal that has a different weight immediately they need to test it and design it first.
Answer:
9.308
Explanation:
The computation of the pH of the given solution is shown below:
But before we need to determine the HI molarity which is


= 0.1852 M
Now
As we know that

So,

Now the molarity of
left is
= 0.397 - 0.1852
= 0.2118


= 4.692
Now as we know that
pH = 14 - pOH
= 14 - pOH
= 14 - 4.692
= 9.308
We simply applied the above equations
Answer:
Van't Hoff factor for AlCl₃ = 3 (Approx)
Explanation:
Given:
Number of observed particular = 1.79 M
Number of theoretical particular = 0.56 M
Find:
Van't Hoff factor for AlCl₃
Computation:
Van't Hoff factor for AlCl₃ = Number of observed particular / Number of theoretical particular
Van't Hoff factor for AlCl₃ = 1.79 M / 0.56 M
Van't Hoff factor for AlCl₃ = 3.19
Van't Hoff factor for AlCl₃ = 3 (Approx)
Answer:
Ionic compounds don't conduct electricity very well because the charge carriers can't move through the crystal. They can conduct heat because the kinetic energy itself is the "heat carrier”.
Hope this helps :)
