Which one is a step used for balancing chemical equations?
Count the atoms in each substance in the reactants and products. (Apex)
Which one of the following is a step used for balancing chemical equation?
Determine how long the reaction will take. apex
Explain what is meant by a chemical equation being balanced?
A balanced chemical equation has the same number of each type of atom on both the reactant and product sides. This means that the total mass and charge are conserved during a chemical reaction. Balancing the equation involves adjusting the coefficients of the reactants and products to achieve this equality.
Can an equation can be balanced by placing the appropiate number called a subscript in front of the chemical symbols or formulas?
No, balancing an equation involves adjusting the coefficients, not subscripts. Coefficients are placed in front of chemical formulas to balance the number of atoms on each side of the equation, while subscripts are used to indicate the number of atoms within a molecule.
Why do intermediates not appear in a net chemical equation?
Intermediates are species that are formed in one step of a reaction and consumed in a subsequent step, therefore they are not typically shown in the overall net equation of a chemical reaction. This is because the net equation represents the overall reaction from the starting materials to the final products without detailing the individual steps involved.

Why mole concept is used in balancing chemical equation?
The mole concept is used in balancing chemical equations because it helps to ensure that there is conservation of mass in the reaction. By balancing the number of each type of atom on both sides of the equation using moles as a unit of measure, we can determine the correct stoichiometry of the reaction. This allows us to accurately predict the amount of reactants needed and products formed in a chemical reaction.

Chemists keep track of which substances are used and created in a chemical reaction by writing what?
Chemists keep track of substances used and created in a chemical reaction by writing a balanced chemical equation. This equation accounts for the reactants (substances used) and products (substances created) in terms of their chemical formulas and stoichiometry. Balancing the equation ensures that the law of conservation of mass is obeyed.
What is a balancing equation?
A balanced equation in chemistry shows the same number of atoms of each element on both sides of the reaction arrow. This is achieved by adjusting coefficients in front of chemical formulas to ensure that the law of conservation of mass is followed.

Why must a chemical reaction be balanced before it can be used in stoichiometry?
Balancing a chemical reaction ensures that the number of atoms of each element is the same on both sides of the equation. This is crucial for stoichiometry calculations as it allows us to accurately determine the relationship between reactants and products based on the balanced equation. Without balancing, the calculations would be incorrect and unreliable.
Can a decimal be a coefficient in a chemical equation?
Yes, a decimal can be a coefficient in a chemical equation. It is used to represent the stoichiometry of the reaction when the reaction requires a fractional amount of a reactant or product. It is common in balancing equations involving gases or rates of reaction.
How can one tell how much reactant will be used in a reaction?
from a balanced chemical equation
What symbol is used in a chemical equation to indicate yields?
The symbol used in a chemical equation to indicate yields is the arrow "->". This arrow separates the reactants from the products in a chemical reaction.
