Answer:
A. The relationship between the Sun,Moon,and Earth
Explanation:
Answer:
C5H7N
C10H14N2
Explanation:
ok so lets lay out this nicely
elements C H N
percentage 74 8.7 17.3
mass number 12 1 14
divided percentage by mass 6.167 8.7 1.2357
now divide the smallest number with the 4.99 7.04 1
rest for instance 1,237 is the smallest.
so 6.167÷1,237
and 8.7 ÷1.237
and 1,237 divide 1.237
now the ratio is C5H7N
now for molecular formula find Mr of C5H7N which is (12×5)+7+14=81
next divide 162.1÷81=2
so now for molecular formula just multipily everythng by 2
C10H14N2

N<span>etwork of bonded ions is established</span> between two atoms due to transfer of electrons from one atom to the other.
therefore,
Sodium chloride is formed from a network of bonded ions.
hence the right answer is <span>D) salt, NaCl</span>
