What is chemical reaction explain with an example?
A chemical reaction happens when one or more chemicals are changed into one or more other chemicals. Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water. things burning or exploding.
Which of the following is an example of chemical reaction in matter?
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding.
How do you write a chemical reaction?
A chemical equation is the symbolic representation of a chemical reaction. The reactants (the starting substances) are written on the left, and the products (the substances found in the chemical reaction) are written on the right.
What name is given to the chemical involved in a chemical reaction?
reactants
What are the four information given by an equation?
Answer Expert Verified (a) The four types of information given by an equation are as follows : (i) Physical state of reactants and products. (ii) Conditions such as temperature, pressure and heat. (iii) Catalyst involved.
What information is covered by a chemical equation?
Information provided by a chemical equation: The formulas and symbols of the substances used. The reactants and products used in the equation. The proportion in which substances react and produce new substances.
What information does a balanced equation convey?
A balanced chemical equation gives the identity of the reactants and the products as well as the accurate number of molecules or moles of each that are consumed or produced.
How do you interpret a balanced chemical equation?
Complete answer: -In the balanced chemical equation, the reactants are written on the left side of the chemical reaction and the products are written on the right side of the reaction. -From the balanced chemical equations we can interpret as follows: -Relative masses of the reactants and products.
How do you write a balanced chemical equation from a word problem?
Step 1: Identify reactants and products and place them in a word equation. Step 2: Convert the chemical names into chemical formulas. Place them based on the chemical equation and write the state symbols. Step 3: Balance the chemical equation.
What is the meaning of used in chemical equation?
Answer: chemical reaction using symbols of the elements to indicate the amount of substance, usually in moles, of each reactant and product.
Is state change a chemical reaction?
A physical change, such as a state change or dissolving, does not create a new substance, but a chemical change does. In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products.
