Answer:

natural resources: materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain.

renewable resources:  a natural resource that is unlimited or that is naturally replenished rather quickly, such as sunlight or water

non renewable resources: (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption.

An atom has 9 electrons and 9 protons at the start. If it loses 2 electrons, the net charge on the atom will be 8-2-2+8+. If the
Mrrafil [7]

Answer: 1) p⁺ = 22; number of protons.

e⁻ = 19 - 1 = 18; number of electrons.

Net charge is +4, because atom has 4 protons more than electrons.

Proton is a subatomic particle with a positive electric charge of +1e elementary charge.

2) p⁺ = 22; number of protons.

e⁻ = 19 + 3 = 22; number of electrons.

Net charge is 0 (neutral charge), because atom has same number of protons and electrons.

Hope this helps :)

HELP: MODELING MOLECULES!!!!!!!!!!!!!!!!

<span>Sulfur Hexachloride SCl6 So now we count the number of valence electrons each has by seeing what column it's in, (1-8) not counting the columns of the transition metals. Since Sulfur is in the 6th and Chlorine is in the 7th, and there are 6 chlorines, we can add up all their valence electrons: 6*1+7*6=48 valence electrons. But remember that electrons come in pairs, either in bonds or as lone pairs. So I usually divide the valence electron number by 2 and just think about placing pairs. It's up to you, but I think it's convenient since we can count "1" in our mind each time we place a bond or a electron pair. So we need to place 24 pairs/bonds. So we can guess that sulfur is a central atom and draw out a bond from sulfur to each chlorine. Since Sulfur is in the 3rd row it can use d-orbitals to break the octet rule. So when we bond all the chlorines onto sulfur we get:
(see the figure)

and 
</span><span>So we made 6 bonds, that means we used up 12 electrons, so if you're counting (AND YOU SHOULD BE!) you have 36 electrons or simply 18 electron pairs left to place. Now let's give chlorine a neutral charge.</span>

The ph of a substance equals −log[h+] where [h+] is the concentration of hydrogen ions. [h+] for tomato juice is 10−4. what is t
Wittaler [7]
 The   Ph  of  tomato   juice  is  calculated  as follows

Ph  =  -log (H+)

if  H+   ion  concentration   is  10^-4

Ph  is  therefore =  -log  (10^-4)  =4

the  tomato  juice  has  a  Ph  of  4
