NH3(g) will take the shape of and completely fill a closed 100.0 milliliter container.
Answer:
3
Explanation:
left side has 2 N so right side must have a 2 which means 6 H on right side so to get 6 on left you have a coef. of 3 to make 6 H
Answer: 3.01 x 10^24 atoms
Explanation:
Based on Avogadro's law:
1 mole of any substance has 6.02 x 10^23 atoms
So, 1 mole of water = 6.02 x 10^23 atoms
5 moles of water = Z atoms
To get the value of Z, cross multiply
Z x 1 mole = (6.02 x 10^23 atoms x 5 moles)
Z•mole = 30.1 x 10^23 atoms•mole
Divide both sides by 1 mole
Z•mole/1 mole = 30.1 x 10^23 atoms•mole/ 1 mole
Z = 30.1 x 10^23 atoms
[Place the value of Z in standard form]
Z = 3.01 x 10^24 atoms
Thus, there are 3.01 x 10^24 atoms in 5 mole of water
<span>Starch and
cellulose have the same substance but different structures. They are both
polysaccharides. The basic unit of a polysaccharide is the glucose. Glucose,
which contains carbon, hydrogen, and oxygen, have two forms. The alpha-glucose
with an alcohol group attached to carbon 1 is down and the beta-glucose with
the alcohol group attached to carbon 1 is up. Starch is the alpha-glucose while
cellulose is the beta-glucose. Starches are linked into a straight chain whereas
the cellulose are connected like a pile of stack paper. When the human body
eats starch, it can digest the starch but not the cellulose because it has no
enzyme that can break it down. </span>
Deuterium is a relatively uncommon form of hydrogen, but can be created from water.
- Heavy hydrogen commonly known as deuterium
- stable isotopes of hydrogen
- gets its name from the Greek word deuterons means second.
- has only one proton and one neutron
- nucleus of the hydrogen's deuterium atom is known as a deuteron containing one proton and one neutron.
- Deuterium forms chemical bonds that are stronger than regular hydrogen
- gas deuterium is colorless
- Deuterated water is used in Magnetic Resonance Spectroscopy.
- used in the determination of the isotopologue of various organic compounds.
- used in Infrared Spectroscopy.
