Answer: Option (d) is the correct answer.
Explanation:
Carbon tetrachloride 
is a non-polar solvent. Whereas out of the given options, 
, 
, 
, and HI are all polar molecules.
On the other hand, only 
is non-polar molecule.
Also it is known that like dissolves like.
So, being non-polar 
will dissolve the give alkane, .
Strontium atom loses 2 electrons to become an ion with 2 electrons lesser than its atom. Your answer is C.
Answer:
See details below
Explanation:
The balanced reaction equation is given below:
+ 
→ 
+ 
Mole fraction of CO2 to H20
= 8/10 = 
Mole ratio of C4H10 to CO2 is 2:8 = 1:4
1 mole of n-butane - 38.12 g
4 moles - ?
= 152.48g fuel consumed.
1. An atom has an equel number of protons and electrons. Since protons are positive and electrons are negative, they are balanced out and there is no charge.
