What is the difference between a reactant and a product in a chemical reaction?
Substances initially present in a chemical reaction that are consumed during the reaction or a substance that participates in a chemical reaction, esp a substance that is present at the start of the reaction while the end product of some chemical reactions yield products.
Why is a catalyst written above the arrow in a chemical equation rather than with the reactants?
The enzyme is written above the arrow of the chemical equation because it is involved in the reaction without being changed by it or used up in the reaction. It is not a reactant or a product.
Is decomposition reaction a chemical reaction?
It depends on the nature of the decomposition. if you are talking about biodegradeability in a substance, then no, its decomposition is mainly due to bacteria that will break down the various particles in the substance ("eat" them). There are, however certain chemical reactions which take place within the bacteria as the substance is being broken down, (much like those that happen in the human body) and the possibility of there being other products in the vicinity which may react to the substance (and degrade it) is always present. It could be said that decomposition is therefore a chemical reaction (or rather a series thereof), but with biodegradeability in mind it is not generally thought of as such.
Why are the properties of reactants different from that of products?
The products of a chemical reaction have different properties than the reactant because they underwent a chemical change by definition of a chemical reaction. The products are new combinations atoms forming different molecules.
For the chemical reaction H2 CO2--H20 Co the energy contained in the reactants is 352 kj and the energy contained in the products is 394 kj assuming 1 mol of each substance is present is this true?
42 kJ is released, and the reaction is exothermic
What is present after a chemical reaction?
That depends on the chemicals present before the chemical reaction and sometimes the conditions under which the chemical reaction occurred.
Are the substances that present when a chemical reaction begins the products?
The substances that are present when a chemical reaction begins are reactants, at the end of the reaction they form products.
What is a chemical reactants and the products in the reaction?
Substances initially present in a chemical reaction that are consumed during the reaction or a substance that participates in a chemical reaction, esp a substance that is present at the start of the reaction while the end product of some chemical reactions yield products.
What is anaerobic reaction?
An anaerobic reaction is a chemical reaction that does not require oxygen to be present.
The substances present when a chemical reaction begins?
The substances that are present when a chemical reaction begins are reactants, at the end of the reaction they form products.
What happens to the atom in a chemical reaction to the product side?
In he chemical reaction the atoms aren;t present anylonger
Is it trueThe substance that are present when a chemical reaction begins are the products?
No: the substances present at the beginning of reaction are the reactants or reagents.
What element do in a reaction?
What do elements do in a reaction? A: The elements that are present form a chemical bond. This happens because of the fact that the elements that are present to form such combine together to make the chemical bond.
What is being produced when bubbles are present during a chemical reaction?
a gas
The matirials present at the beginning of a chemical reaction are called what?
Reactants => Products
Is it true that if the substance that are present when a chemical reaction begins are the products?
true
Why does vinegar cause sedimentary rocks to fizzle?
Vinegar, which is acidic, reacts with the calcite or limestone present in sedimentary rocks, resulting in the release of carbon dioxide gas. The fizzing or bubbling you observe is the visible evidence of this reaction. This reaction between the acid and the calcium carbonate in the rock is similar to the reaction that occurs when acid is added to baking soda.
