Answer:

The answer is still 4.7

Explanation:

The first digit before a decimal (to the left) is called unit or one. However, the first digit after a decimal (to the right) is called tenth, and the one after that is called hundredth.

when rounding up, any digit greater than 4 will be rounded up to 1 and then added to the preceding number. But when the digit is less than 5, the number is rounded off to 0.

Hence, 4.7 is the same as 4.70 with the "7" being the tenth value and the "0" being the hundredth value. Hence, when 4.7 is rounded to the nearest tenth, it remains as 4.7 because its hundredth value is rounded off to "0" since it is less than "5".

explain how the number of valence electrons in atoms relate to their bonding with other atoms to form molecules ?????
Westkost [7]


valence electrons are the number of electrons in the outer shell. there can only be 8 electrons in the outer shell. The number of valence electrons can be used to determine how many bonds are needed.

For example: H2O

O (oxygen) has 6 valence electrons
H (hydrogen) has 1 valence electron

O needs 2 more electrons to be stable
H needs 1 more electron to be stable

O forms one bond with two H atoms to form H2O.

Answer:

In short, because we are tearing up the oxygen factories to make way for carbon dioxide emitters. (Doesn't make a lot of sense, read the explanation)

Explanation:

So, 1000 years ago, we had a lot more trees, didn't have engines or cars or factories or anything, really that released carbon dioxide into the air and we had a lot more trees and since the invention of cars, engines, carbon dioxide-emitting tools and factories and all the other things that emit "Greenhouse gases" and in doing that, cleared more trees to make room for factories and roads and that has drastically changed the outlook of the carbon cycle.
