Answer:
V2 = 271.1 ml
Explanation:
Given:
P1 = 1.03 atm
V1 = 250 ml
P2 = 0.95 atm
V2 = ?
P1V1 = P2V2
V2 = (P1/P2)V1
= (1.03 atm/0.95 atm)(250 ml)
= 271.1 ml
Answer:
1. Dipole-Dipole
2. Hydrogen bonding
3. London dispersion forces
Explanation:
- First, you need to be familiar with each of these terms.
- Secondly, you need to know how to calculate electron negetivity.
Once you know both of these things, all you do is match the defintions.
- Hope this helps! If you would like me to thoroughly explain this to you please let me know, as I would be glad to do it.
Answer:
Yes
Explanation:
Neither Calcium nor hydrogen nor oxygen are alkali metals
- Alkali metals are Group 1 elements
- They are very soft and mellable.
- H,Li,Na,K,Cs,Fr are included in it however H is not a actual member
Here
Ca(OH)_2 is the compound
Vant Hoff factor is 3
As it's greater than 1 it's a very strong base .
The pOH of this comes around 1.5 to 1.3
So very heavy ionic dissociation
Strong Alkali
A is incorrect because Mg has a 2+ charge, while SO4 has a 2- charge, if there is 2 Mg and 3 SO4 then the formula will not add to 0 meaning neutral
Answer:
Okay so Carbon's is 6, then Neon is 10, Silicon is 14, and Barium is 56.
