Answer: a ) NaCl
b) No compound.
Explanation:
Atomic number of A is 11 , thus it is sodium. It has electronic configuration of 2,8,1 and thus has 1 valence electron and can form
.
Atomic number of B is 18 , thus it is argon. It has electronic configuration of 2,8,8 and thus it is an inert gas.
Atomic number of C is 1 , thus it is hydrogen. It has electronic configuration of 1. It can only share electrons.
Atomic number of D is 17 , thus it is chlorine. It has electronic configuration of 2,8,7 and thus has 7 valence electron and can form
.
a) A and D :
Here Sodium is having an oxidation state of +1 called as
cation and anion is
. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral 
b) B and C
As B is an inert gas , it wont combine with C.
Answer:
Mass of liquid ammonia is 0.035g.
Explanation:
I hope this will help u
Have a nice day
The answer is C: the more polar the molecules, the stronger the force. Hope this helps!
Take heat away from oxygen and it becomes liquid oxygen. Take heat away from steam and it becomes liquid water.
Percentage yield = actual yield/theoretical yield
So divide 21.0 g by 22.7 g and multiply it by 100 to find the percentage yield
