FOR 50 POINTS & A BRAINIST*

Chemistry
1 answer:
Reika [66]3 years ago
5 0

Answer:

1. A

2. D

3. D

4. B

Explanation:

Sulfer is in the 3rd period of the periodic table meaning that 2 periods came before it hence the 2 electron shells and it is in the 6th group hence the 6 valence electrons.

Using this logic we know that the element in the 5th period and the 7th group which would be Iodine

We also know that the element in the 4th period and 8th group is Krypton

The Lewis dot model is more commonly used to show chemical reactions, I haven't heard of the addition or subtraction models before so there's a chance that it may only be part of your curriculum, or they are answers made up for your multiple choice.

Hope this helps!!!

PLEASE HELP QUICKLY! SERIOUS ANSWER PLEASE
yarga [219]

Answer:

Q1: A

Q2: B

Explanation:

Q1: the independent variable will always go on the x axis and the dependent will always go on the y-axis, so the answer is A.

Q2: it's not a, it's not d (ocean droughts aren't a thing that I'm aware of), and hurricanes don't make water scarce, so I would go with B.

Draw arrows for all of the attractive and repulsive forces between the negatively charged electrons and positively charged proto
Sophie [7]

Answer:

Attraction

(e-) ---> <--- (H+)

Repulsion:

<---(e-) (e-)-->

Neutral:

(e-)       (Helium)

Explanation:

Accordingly to coulomb's law:

In the attraction, the hydrogen without an electron has a positive charge and needs to be fulfilled with a negative charge found in an eletron.

In the repulsion, both electrons has the same charge and repulse each other.

In the neutral case, the Helium is highly stable therefore the electron is not attracted.
