Chlorine molecule is orbital and dot structure

The electron dot structure of

Explanation:

Step 1: First we have to know the number of valence electrons present in a molecule.

Chlorine is an element from group 17 with 7 nos. of valence electrons.

So, the given will have 7+7 = 14

Step 2: We, will begin by drawing the skeleton of the molecule.

Step 3: Then, we have to place the bonding pairs of the electrons in the middle atoms so that chemical bonds can be formed.

Step 4: The electrons left will be used as lone pairs for central and terminal atoms in order to achieve an octet and to finish the electron dot structure. The structural formula and electron dot structure has been attached below.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
