Answer:
For H-Cl, the direction is towards the chlorine atom
For F-CH3, the direction is towards the flourine atom.
Explanation:
The dipole moment is a vector quantity. This implies that it has both magnitude and direction.
Thus, the direction of the dipole moment always points from the positive atom towards the negative atom.
This explains the fact that it points to chlorine in HCl and points to flourine in F-CH3
B, the Internet.
If Caitlin told Teddy that the largest diamond was found YESTERDAY then it wouldn't be in last month's science magazine. It also wouldn't be able to be in an encyclopedia at the library because there wouldn't have been any time to write, publish, and for the library to get the encyclopedia in one day. Caitlin's parents may not know about Caitlin's claim or about the diamond in the first place. The Internet would likely have an article about the news-breaking diamond as soon as possible.
The density would be the same for the whole bar as well as one half of the bar. Density is a identity I believe, by this I mean that it stays the same no matter how little or how much of the same substance you have. Since density = mass / volume, half the bar has half of the weight as well as half of the volume of the whole bar, making the density the same.
For example, a block weighs 10 grams and has a volume of 5 ml. the density would be d = 10/5 or, d = 2g/ml
Half of the block weighs 5 grams and has a volume of 2.5 ml. The density is d = 5/2.5, or, d = 2 g/ml.
See, although there are different amounts of the same substance, their density is the same.
A covalent bond is a form of chemical bonding between two non-metals, whereas ionic bonding is a bond between a metal and a non-metal.
Answer:
2Na+F2 yields 2NaF is balanced.
Explanation:
There are 2 sodium and 2 fluorine in both reactants and product: In 2NaF the 2 is distributed because it is in the beginning of the compound.
