When writing a chemical equation what must be written first?
First write down what you know. Reactants go on the left, followed by an arrow, with products on the right. Balance the equation.
Why physical states of reactants and products are mentioned while writing a chemical equation?
It is not obligatory but it is important as indication for other chemists or students.
What does conservation mean when relating to chemical reactions?
"Conservation" in chemical reactions referrs to something that is the same before and after the reaction. When writing a chemical equation, balancing the equation represents the 'conservation of atoms' and the 'conservation of mass'. Add all the atoms of each individual type on the reactant side of the arrow and, individually, the number of atoms on the product side for each type of atom will be the same. Atoms cannot be created or destroyed by a chemical reaction.
Why does his teacher ask him to balance the equation by including the correct coefficients?
It is important to balance the equation, so that you know the exact ratio of reactants required and products formed. If you don't consult a balanced equation, some of your reactant may not completely consume in reaction or sufficient product is not formed during experiments.
What doe hydrogen peroxide and manganese dioxide form?
H2O2, or Hydrogen Peroxide is combined with MnO2, Manganese Dioxide, to form H2O, water, and O2, oxygen gas. The Manganese Dioxide serves as a catalyst in this reactions since it is not a reactant, but sets the reaction in motion. Therefore, when writing the chemical equation, one should place MnO2 beneath the yield sign. One's balanced chemical equation should look like this: a. 2H2O2(L) ==> 2H2O(L) + O2(g) MnO2(s)
What a short easy way to show a chemical reaction using symbols?
Writing a chemical reaction with symbols: Ex.: NaCl + AgNO3 = AgCl (s) + NaNO3 A mathematical (digital) system for the writing of chemical equations exist but it is rarely used.
What is a symbolic way to write out a chemical change?
Writing out a chemical equation for a specific chemical reaction.
How do chemist indicate a reversible reaction when writing a chemical equation?
With this symbol:
What is a shorthand way of writing a chemical reaction?
A chemical reaction is always written with the reactants (the things you mix together to do the reaction) on the left and the products (the stuff you get) on the right. In between is an arrow pointing right to indicate that the reactants react and become the products. Catalysts are sometimes listed above the arrow. And don't forget to balance the equation.
What is the shorthand form for describing chemical reactions?
write down the formula for any substance entering into reaction.place the (+) sign between the formulas as needed and put the yield after the last one.
Could you say a new substance was form after copper and sulfur were ground?

Ions that appear on both sides of a chemical equation are?
Ions that appear on both sides of the equation are spectator ions. These ions do not participate in the reaction at all. Thus, they are omitted when writing the net ionic formula of a reaction.
What is the purpose of writing a word equation in chemistry?
It is one way of representing a chemical reaction: it tells you what reacts and what is produced. Word equations are an efficient way to describe chemical changes, to help chemists recognize patterns, and to predict the products of a chemical reaction.
When writing a chemical reaction for an exothermic process will the heat energy be reactant or product?
Heat will be on the product side of the equation, but it is not a "product" in the same sense as the chemical symbol(s) and/or formula(s) written on this side of the equation, because heat is not a tangible substance but rather an increase in the energy of nearby substances.
What is the use of H2CO3?
Carbonic acid is used in the making of soft drinks. H2CO3 is used to represent the two species when writing the aqueous chemical equilibrium equation.
