Answer:
e. do both (a) and (b).
Explanation:
Covalent bond
This is another type of chemical bond, through which atoms can also have 8 electrons at their last energy level, and thus comply with the law of the octet.
The covalent bond is defined as the union of non-metal atoms to share their valence electrons, by means of electromagnetic attractive forces, mainly; Here atoms do not gain or lose their electrons, but share them in quantities of one, two, three and even four in various situations. The last electron layer of the atoms that bind together is intertwined or overlapping, forming the true molecules, contrary to what happens in the ionic bonds, in which the united atoms only approach each other to form true aggregates, instead of true molecules. In general, atoms of organic substances have this type of bond and, in addition, it is very common among atoms of the same class or species (Chlorine with Chlorine, Oxygen with Oxygen, Carbon with Carbon)
Answer:
A
Explanation:
the circles are more tightly packed together in box A than in box B in the same amount of space
Answer:
3.56 x 10^3
Explanation:
In order to put in in scientific notation, the number must be between 1-10 and must be multiplied by a power of 10. We can turn 3560 into a number 1-10 by moving the decimal up.
We move it up 3 spaces. 3.560
Since we moved it up 3 spaces, we need to multiply it by 10^3
3.56 x 10^3
When a solid is added to a liquid, there exists a possibility that it will get dissolved in the solid. However, this depends on a lot of factors, like the temperature of the substances, the volume of the liquid, and the amount and nature of the solid to be dissolved.
