Density of boat =
=
= 0.88 g / cm³
Since the density of water is greater than the density of the boat ( 1 > 0.88) then that means,
the boat will NOT sink.B.
Searching for this question, I found the options on the internet.
"1.<span />Two atoms share electrons so they can fill their outer shells<span>2.The constant motion of electrons and the creation of charge imbalances bonds two molecules together3.A hydrogen atom with a slight positive charge is attracted to a negative charge of another molecule or atom4.One atom loses one or more electrons and the other atom gains one or more electrons"
The correct answer would be number 1. A covalent bond is achieved when two atoms share electrons from their outer shell so that they have a full outer shell leading to the electronic configuration balance they need.</span>
Answer:
B
Explanation:
to find how many moles we have you need to use the molarity equation which for this is
40g * (1mole/200g) = .2 moles
Given we know that we have .2 moles
then all you have to do is divide amount of moles by amount of liters to find the molarity
for this problem it is
.2mol/2L which is .1 M
