What does this mean? Write a response in complete sentences. plz someone help!!!!!!!

Answers

Answer: High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.

Nitrogen has an atomic number of 7. Its atomic mass is 14. Nitrogen has _____.

seven electrons
seven neutrons
seven electron shells
23 neutrons
14 electrons

Please help (:

Answers

Seven electrons. The atomic number of a element is also the amount of protons and electrons it has.
As atomic Number is number of protons Or number of electrons so
N has 7 electrons
Neutrons= Mass no.- Atomic Number
= 14-7
N has 7 neutrons
N doesn’t have 7 electron shells because shell 1 can hold 2 electrons and shell 2 can hold 8 electrons
It doesn’t have 23 neutrons and 14 electrons

So, Seven Electrons and seven neutrons is correct

why is compound not a mixture?

Answers

Compound is a pure substance containing two or more elements that are chemically combined in a fixed ratio but mixture is made up of two or more substances that are not chemically combined.
The way my chemistry professor explained it was compounds are from the same side (nonmetals), so they don’t necessarily mix well. It would be different if it was an ionic bond, because ionic bonds are when metals and nonmetals mix.
