What is the difference between two chemical formulas?
A chemical symbol is the short version of the chemical name given to an element. The chemical symbol appears on the Periodic Table, is 1 or 2 characters long and is derived from the Latin name of the particular element. As an example, Gold's chemical symbol is Au, which stands for the Latin word "Aurum". A chemical formula is an abbreviated description of a compound, with a compound being a chemical made from more than one single element. The formula uses the chemical symbols, in a precise pattern that follows the make-up of the compound, to accurately describe the chemical's elemental and electrical structure. An example of a compound, or chemical formula, is H2O. 2 parts Hydrogen to 1 part Oxygen. The H is the element (or symbol), as is the O, whereas the H20 is the formula (or compound).
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What does the element CO stand for?
What is 'co'? You must be careful when writing chemical formula. They have different meaning and names. 'co'. Not known. Co is Cobalt. CO is carbon monoxide, Remember for all chemical formulae and symbols. A single letter symbol is ALWAYS a CAPITAL letter. e.g. H (hydrogen) A two letter symbol has a CAPITAL letter , to start, followed by a small case letter. e.g. Na (Nadium ; Sodium) No chemical formula has two small case letters., hence 'co' is a nonsense.
Start up energy of a chemical reaction?
Energy that starts a chemical reaction is called activation energy
What is needed for a chemical reaction to start?
For a chemical reaction to start, firstly, there should be physical contact between the reactants...!!! Also, sometimes: a special temperature or pressure, a catalyst, etc.
What is the chemical formula for iron filling?
Iron fillings are pure iron - until they start rusting. So their formula is Fe.
How many potassium atoms are in the reactants of the chemical reaction?
The same number you started with. In every chemical reaction the total number of atoms at the start is the same as the number of atoms at the end.
What is the definition for next current formula?
It is the number that is added, subtracted, times, or divide in a pattern to (n) or the start number.

What is the organic name of ch3ch2ch2ch2ch2co2ch2ch2ch3?
Hexan-2-ol hex' because it's a 6 chain carbon and 2 because you choose the end to start from that gives you the smallest number. an 'ol'
Where is the start of chemical digestion?
the start of chemical digestion is the mouth and ends in the small intestine. This is true and the saliva has the power of the chemical digestion
How will you create a basic formula after selecting the cell in which you would like to use the formula?
After you select the cell, just start typing your formula. Always start a formula with the = sign. [=sum(a1:a5)]
The amount of energy needed to start a chemical reaction is called what?
The energy required is called the activation energy. The minimum amount of energy needed to start a chemical reaction is given by the formula Ea=-RT*ln(k/A). R is the universal gas constant, T is temperature in Kelvin, k is the reaction rate coefficient and A is the frequency factor.
What sign must be typed at the beginning and end of cell locations in a formula?
An equals sign is needed at the beginning of a formula. There is no particular character needed at the end of a formula. A cell reference will begin with one or more letters and end with a number. If it is an absolute reference, it would start with a $ sign. A mixed reference will start with a $ sign or a letter.
When did chemical engineering start?
1780
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What energy is needed to start a chemical reaction?
It varies with the differences in chemical reactions
