<u>Answer:</u> The volume of bone for given sample is 30.49cm^3

<u>Explanation:</u>

To calculate volume of a substance, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

Density of bone = 820mg/cm^3=0.82g/cm^3      (Conversion factor:  1 g = 1000 mg)

Mass of bone = 25 g

Putting values in above equation, we get:

0.82g/cm^3=\frac{25g}{\text{Volume of bone}}\\\\\text{Volume of bone}=30.49cm^3

Hence, the volume of bone for given sample is 30.49cm^3

How is the law of conservation of matter represented in a chemical reaction?
blondinia [14]

Answer:

By balancing the chemical equation  

Explanation:

The Law of Conservation of Matter states that matter cannot be destroyed nor created.

That is, you must have the same amount of matter before and after a reaction.

Atoms are made of matter, so you must have the same number of each type of atom in the reactants as in the products. You must balance the equation.

Consider the reaction

2H₂ + O₂ ⟶ 2H₂O

You must have 2s in front of H₂ and H₂O to balance the atoms.

They give you four atoms of H and two atoms of O on each side of the arrow.

Write a description of your dream car by using powerful adjectives. Write about 100-120 words​
hodyreva [135]

Answer:

It was a cold December night shortly after dusk, a likely setting for an event that would prove to be life altering. As fate would have it, this would be the night that I lost the material possession that truly meant the most to me. I would lose the one thing that gave me much pride and joy and excitement. I often think back and liken us to a newlywed couple, for we had only been together for 18 months and were still very much honeymooning. It was a night, a moment, that even now scoffs and mocks me as I travel thither and yonder with her replacement. But she can never be truly replaced and to call my current fix a replacement seems like a sort of blasphemy.

I called her my Blue Angel. That's right! She was a brand new 1999 Atlantic blue Ford Mustang fully equipped with white racing stripes on each side, dark window tint, a rear spoiler, and a post-factory sound system that I installed personally just to complete the "dream ride" effect. We met on April 24, 1999,when my parents introduced us and told me she was all mine as a reward for graduating high school as valedictorian. And what a reward she turned out to be. We went everywhere together. I took her out to eat. When I'd go play ball somewhere, she went with me. Every day from April 24, 1999, to December 22, 2000, we were together. We were bonding in a way a young man can bond with no other, and there truly was no other for me. Other guys had bigger trucks and faster cars, but where my Blue Angel was lacking in size and power, she more than made up for in pure, unadulterated, raw emotion, She never let me down; she was always looking her best and never longing for attention from me or any of the other countless admirers and fans she won over for...
