What is a hb 2 pencil?
I've never heard of an 'HB #2' pencil. I'm saying that no one makes them! But this is what I know about pencils. 'H' pencils are typically used for graphic drawings. The lead is harder and the lines tend to be lighter and thinner. The lead is less prone to smearing. The higher the number, the lighter and harder the lead. Then we have the 'B' pencils. The lead is softer, darker, the lines tend to be thicker. As the number gets higher, these qualities increase. A 6B pencil gives a very dark, thick line. These pencils are used more commonly for sketching in the typical 'drawing', like an artist's picture. These leads smear on paper easily! As an architectural student, I'm required to use an 'HB' pencil. This is just a blend of H and B leads. It still has an annoying habit of smearing on vellum! I usually stick to H2 pencils and higher whenever possible to keep my work clean!
How do you determine the distance between two graghed points?
Use Pythagoras' thereom! h2= a2 +b2. Draw a line between the points, make a right angle triangle and you should figure it out from there :)
If a microbe uses Co2 for carbon and H2 for energy the microbe is?
chemoautroph
How many grams of H2 are needed to produce 13.14g of NH3?
The balanced equation for the formation of NH3 is N2 + 3 H2 --> 2 NH3. 13.64 grams of ammonia is equal to .801 moles. Then 1.2015 moles of hydrogen are needed, or 2.42 grams.

What is the difference between H2 and 2h?
H2, on Runescape may be a herald number e.g Rune Helm (h2) or Black Kite Shield ( h2 ) where as 2h means 2-handed, as in Dragon 2h sword, meaning Dragon two handed Sword.

What is the difference between sodium chloride and water?
Sodium chloride is NaCl. Water is H2O.
Which has a strong bond H2 or H2 plus?
H2+ has a stronger bond than H2. The addition of a positive charge to the H2 molecule increases the attraction between the two hydrogen atoms, resulting in a stronger bond.
What is the difference between formula H 2 and formula HCI?
H2 is the formula for pure Hydrogen gas, whereas HCl is Hydrochloric Acid, which is a compound of Hydrogen and Chlorine.
What type of bond will form between elements with similar high elecronegativities?
This is an ideal covalent bond - possible only between identical atoms of an element (H2).Between atoms of two elements a difference of electronegativity exist always.
What is the difference between a compound and a molcule?
A compound is two or more elements combined. Like H2O or NaCl. A molecule is the basic unit of a compound like O2, H2, N2.
What is different between H2 and 2H?
H2 is the symbol for the diatomic molecule of hydrogen; 2 H meaning is two hydrogen atoms.
