<u>Answer:</u>
Density is mass per unit volume.
Its formula is
Density = Mass / Volume
Its units can be kg/L or kg/(
) or g/mL or g/(
)
Density of various substances are given. The more denser substance goes to the bottom of the graduated cylinder.
Air on the top then comes Wood followed by Corn oil followed by Ice and then Water followed by Glycerin then Rubber then Corn syrup and at last Steel at the bottom which will more denser than all the substances mentioned above.
The staking up of the substances is in the order mentioned below in the tabular column
If there was an inverse relationship between the temperature and the volume, our daily lives change because in high temperature things will contract.
<h3>What if there was an inverse relationship between the temperature and the volume?</h3>
If there was an inverse relationship between the temperature and the volume then with increasing temperature decrease occur in the volume of a substance. If this type of relationship is present in the world, the objects will contract when the temperature is high and expand when the temperature is low which make the solid materials expand at winter and contract at summer season.
So we can conclude that if there was an inverse relationship between the temperature and the volume, our daily lives change because in high temperature things will contract.

Pros: The rate at which modern medicine is advancing is astonishing. You can sit on your couch and watch TV and see commercials for new medications at an alarming pace — and these new medications have reduced our death rates for stroke, heart disease, and cancer. In fact, due to modern medicine, the death rate from heart disease has decreased by 60% since 1970! The death rate for HIV/AIDS has dropped more than 75% since 1995, when its was at its peak.
Cons: However, critics of modern medicine are quick to point out that there is a pill for everything . Yes we are quick to create more drugs, and yes, we are living longer due to said drugs but are we living better?
Medicine has evolved, and we now have surgeons who are able to perform surgeries robotically. But critics point out that medicine has evolved to the point that we are treating disease instead of preventing it .
Answer is: H₃PO₄.
A
phosphoric acid is three protic acid, which means that in water release tree
protons. Phosphoric acid ionizes in three steps in water.
<span>
First step: H</span>₃PO₄(aq) ⇄ H₂PO₄⁻(aq) + H⁺(aq).<span>
Second step: H</span>₂PO₄⁻(aq)⇄ HPO₄²⁻(aq) + H⁺(aq).<span>
Third step: HPO</span>₄²⁻(aq) ⇄ PO₄³⁻(aq) + H⁺(aq).<span>
Species that are present: H</span>₃PO₄,
H₂PO₄⁻, HPO₄²⁻, PO₄³⁻ and H⁺, but because the acid dissociation constants are low, very low percentage of acid dissociates.
This is a statement of the law of Definite Proportions. Basically what it says is that the proportions of mass will always be the same and can't be changed.
