Chemistry Formula

Did you know that you can cool yourself to H2O is water and H2O2 is hydrogen peroxide. What is H2O4?

Have you heard the one about a chemist who was reading a book about helium? He just couldn't put it down. How about the chemical workers… are they unionized?

Did you know that oxygen went for a second date with potassium? How did it go? Why do chemists like nitrates so much?

They're cheaper than day rates. A: CoFe2 Q: What is the chemical formula for "banana"? A: BaNa2 Q: What do you do with a sick chemist? A: If you can't helium, and you can't curium, then you might as well barium.

Q: Did you hear oxygen went on a date with potassium? A: It went OK. We would like to apologize for not adding more jokes Q: Anyone know any jokes about sodium?

A: Na Making bad chemistry jokes because all the good ones Argon Q: What is the most important rule in chemistry? A: Never lick the spoon! Helium walks into a bar, The bar tender says "We don't serve noble gasses in here. Silver walks up to Gold in a bar and says, "AU, get outta here!

The first one says "I think I'll have an H2O. Q: What did the scientist say when he found 2 isotopes of helium?

A: HeHe Q: Why was the mole of oxygen molecules excited when he walked out of the singles bar? A: He got Avogadro's number! A proton and a neutron are walking down the street. The proton says, "Wait, I dropped an electron help me look for it. The proposed name is: Un-obtainium. As an ion chromatography chemist I made this one up: Anions aren't negative, they're just misunderstood.

The optimist sees the glass half full. The pessimist sees the glass half empty. The chemist see the glass completely full, half in the liquid state and half in the vapor state. Q: What do chemists call a benzene ring with iron atoms replacing the carbon atoms?

A: A ferrous wheel. Q: If H2O is the formula for water, what is the formula for ice?

A: H2O cubed. Q: What did the bartender say when oxygen, hydrogen, sulfur, sodium, and phosphorous walked into his bar? A neutron walks into a bar. He asks the bartender, "How much for a beer? Q: What do you do with a dead chemist? A: Barium Q: What did one ion say to the other?

A: I've got my ion you. Q: Why did the chemist sole and heel his shoes with silicone rubber? This mass proportion will be the same for any water molecule. The relative position of the two methyl groups must be indicated by additional notation denoting whether the methyl groups are on the same side of the double bond cis or Z or on the opposite sides from each other trans or E.

Such extra symbols violate the rules for chemical formulas, and begin to enter the territory of more complex naming systems. However, all these nomenclature systems go beyond the standards of chemical formulas, and technically are chemical naming systems, not formula systems.

If the number of repeating units is unknown or variable, the letter n may be used to indicate this formula: CH3 CH2 nCH3.

Chemistry Formulas - Basic & Important Chemistry Formulas List

Ions in condensed formulas For ions , the charge on a particular atom may be denoted with a right-hand superscript. The total charge on a charged molecule or a polyatomic ion may also be shown in this way. In the latter case here, the parentheses indicate 6 groups all of the same shape, bonded to another group of size 1 the cobalt atom , and then the entire bundle, as a group, is bonded to 3 chlorine atoms. In the former case, it is clearer that the bond connecting the chlorines is ionic , rather than covalent.

Isotopes Although isotopes are more relevant to nuclear chemistry or stable isotope chemistry than to conventional chemistry, different isotopes may be indicated with a prefixed superscript in a chemical formula.

Also a study involving stable isotope ratios might include the molecule 18O16O. A left-hand subscript is sometimes used redundantly to indicate the atomic number. For example, 8O2 for dioxygen, and 16 8O 2 for the most abundant isotopic species of dioxygen.

This is convenient when writing equations for nuclear reactions , in order to show the balance of charge more clearly.

Trapped atoms.Little Willie was a chemist. A: They turn from notating nuclear spins to notating unclear puns. We calculate the molar mass for nicotine from the given mass and molar amount of compound: Comparing the molar mass and empirical formula mass indicates that each nicotine molecule contains two formula units: Thus, we can derive the molecular formula for nicotine from the empirical formula by multiplying each subscript by two: Check Your Learning What is the molecular formula of a compound with a percent composition of In the latter case here, the parentheses indicate 6 groups all of the same shape, bonded to another group of size 1 the cobalt atom , and then the entire bundle, as a group, is bonded to 3 chlorine atoms.

One electron from the metal is transferred to the halogen to produce a metal halide and an alkyl radical.

A: If you can't helium, and you can't curium, then you might as well barium. Reply shubhrum diwaker March 26, at 2: Q: What did the scientist say when he found 2 isotopes of helium?

A molecule of NH3 contains one N atom weighing Its chemical formula can be rendered as CH3CH3.
