Is a series of chemical reactions that can occur that are cyclical without any waste For instance a compound AB plus CD creates A BC and D Then BC plus D creates B and CD A plus B creates AB?

What is the difference between a word equation a formula equation and a chamical equation?
A chemical formula is the way a particular chemical (element or compound) is represented using the letters given in the Periodic Table. For example, the chemical formula of oxygen is O2 and the chemical formula of caron dioxide is CO2A word equation describes a chemical reactionusing the names of chemicals only. For instance, the word equation for respiration is:glucose + oxygen => carbon dioxide + waterA formula equation also describes a chemical reaction, but uses chemical formulae instead of names and is balanced. An example of this would be methane burning in oxygen:CH4 + 2O2 => CO2 + 2H2O
What is difference between an instance variable and a class variable?
An instance variable is typically associated with an object instance of the class whereas class variable is not associated with any object instance. Static variables are referred to as class variables while non-static regular variables are called instance variables. Simply put, you will have as many instances of the instance variable as there are object instances. i.e., if there are 10 instances of an object, you will have 10 instances of that instance variable as well. But, there will be only one instance of the static or class variable. Instance variables are accessed as follows: objname.variableName; Class variables are accessed as follows: ClassName.variableName;
What are solvents?
cleaners which is solvent
What is integration?
an act or instance of combining into an integral whole an act or instance of integrating a racial, religious, or ethnic group an act or instance of integrating an organization, place of business, school, etc
Give two examples of combination reaction?
First of all combination reaction is the one in which two or more reactants combine to form a single product......Such as:CaO + H2O = Ca(OH)2In this Calcium Oxide (lime) combines with Water to form Calcium Hydroxide (slaked lime)...Na2O + H2O = 2NaOHIn this Sodium Oxide combines with Water to form Sodium Hydroxide...4Li + O2 = 2Li2OIn this Lithium combines with Oxygen to form Lithium Oxide...COMBINATION REACTION is just opposite to DECOMPOSITION REACTION in which one reactant breaks down to form simpler products, such as :2FeSO4 = Fe2O3 + SO2 + SO3In this Ferrous Sulphate decomposes to form Ferric Oxide, Sulphur Dioxide and Sulphur Trioxide....SidzSome examples of combination reactions include reactions between two atoms, two compounds, and an atom and a compound. For instance water is formed from hydrogen and oxygen gas.
Is plastic an acid?
No, most plastics are quite inert. Remember that 'plastic' is a type of substance, not an individual compound. Polythene, for instance, has very few reactions, which is why we make chemical storage bottles out of it, for instance for strong acids and alkalis. PTFE is less inert, but still not acidic.
How do chemical reactions affect daily life?
chemical reactions are a big thing during our lives for instance.... if we didn't have water there will probably be no coke, just juice, oranges etc... thats why we need chemical reactions so that we have what we have today and what we use today such as electrical things etc...
How are compounds and formulas related?
All chemical compounds will have a chemical formula. For instance, the calcium chloride has formula CaCl2. Elements, on the other hand, have chemical symbols. Chemical reactions can be represented by chemical equations.
Where do all chemical reactions occur in a cell?
whan a sperm cell enter the egg cell and make a baby thats the huge chemical reaction
Chemical formula of diphosphorus decoxide?
Most chemical compound names are taken from what and how many atoms that they are made of. For instance, diphosphorus decoxide is di- (2) phosphorus dec- (10) oxide, or, P2O10.
How can the number of elements be identified within a compound?
Count the different chemical symbols in a compound's chemical formula to identify the number of elements. For instance, in the formula for sucrose (table sugar) C12H22O11 there are three elements -- C, H, and O. These represent carbon, hydrogen, and oxygen.
Do the elements in the oxygen family tend to gain or lose electrons in chemical reactions?
that would depend on what specifically the were reacting with on each instance.
What is the combinations of chemical symbols that describe the composition of a chemical compound?
Each element is given a symbol (a letter or a pair of letters where the first one is always a capitol letter and the second one is always a small letter). For instance the letter for Hydrogen is an 'H' and for Oxygen is an 'O'. When describing the formula for a chemical compound you use these symbols to say what elements it is made of and you follow each element with a number if there is more than one atom of that element in the compound. For instance water is made of one atom of Oxygen and two atoms of Hydrogen and therefore its chemical formula is: H2O
Why is decomposition of a compound a chemical change?
Decomposition is a chemical change because the nature of the compound that has decomposed is now a different or several different chemicals after decomposition. It cannot be converted back to what it was, and so this is a chemical change.
What is the scientific name C6O6H8 for?
The chemical name of this compound is hexene if it is acyclic. In the instance if it is cyclic, the name is cyclohexane.
What are the differences between coupounds and mixtures?
A mixture can be simply separated For instance a mixture of salt and water water can be separated from salt by evaporating the water. a container of sand and golfballs are a mixture there is no chemical bond holding them together.A compound however is another story For instance take the compound water H2O its made up 2 gases of hydrogen and Oxygen to take them apart involves a chemical reaction.
What is the chemical combination of symbols that represents a compound?
Each element is given a symbol (a letter or a pair of letters where the first one is always a capitol letter and the second one is always a small letter). For instance the letter for Hydrogen is an 'H' and for Oxygen is an 'O'. When describing the formula for a chemical compound you use these symbols to say what elements it is made of and you follow each element with a number if there is more than one atom of that element in the compound.
