Why must chemical equations be balanced using coefficients?
The number of atoms in the reactant and products must be equal to obey the law of conservation of mass.
What do plants do when manufacturing food?
They photosynthesize and produce glucose which is used for growth, and release oxygen as a waste product. They absorb solar energy (sunlight), and transforms it into chemical energy (sugar). Word equation Sunlight + Carbon Dioxide --> Glucose + Oxygen Chemical equation Sunlight + CO2 --> C6H12O6 + O2
What is j in algebra?
it can represent any number it can represent any number it can represent any number it can represent any number it can represent any number
Is orbital with no electron possible?
Yes, it's called an unoccupied orbital. There are actually infinitely many unoccupied orbitals for each atom. They represent possible solutions to the wave equation for the atom, and could potentially be occupied by an electron if the atom enters an excited state.
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
What are the two coefficients?
In a chemical equation, coefficients represent the no. of molecules or atoms involved in a complete chem. reaction.
What information about a chemical reaction is derived from the coefficients in a balanced equation?
Coefficients are used to represent multiple molecules of formula units.
What is a balanced chemical equation . why should chemical be balanced?
A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.
What do the coefficients in a balanced chemical equation represent?
Represents the mole ratios between any two substance
Do the coefficients in a chemical equation represent not only the number of individual particles but also the number of moles of particles?
yes it does
What information can you determine from the coefficients in this balanced chemical equation?
What information can you determine from the coefficients in this balanced chemical equation? Mg + 2HCl → MgCl2 + H2
What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
How are equation coefficients useful in determining amounts of reactions and products?
Equation coefficients show the number of molecules involved in a chemical reaction.
Which do you use to balance equations subscrips or coefficients?
Both. you must have the correct subscripts to represent the correct chemical then you only change the coefficients to balance the equation. The product of a coefficient and a subscript tells how many atoms are present.
What is the relationship between coefficient and balance chemical equation?
balance chemical equation, change only the coefficients of the formulas.
What is the correct set of coefficients for the equation below?
2111.Equation coefficients are needed to write a correct chemical equation
What is the coefficent that shows in a chemical equation?
Equations for chemical reactions may require one or more whole-number coefficients in order for the equation to balance. Balancing a chemical equation upholds the law of conservation of mass, which states that matter cannot be created or destroyed. The coefficients represent molar ratios of reactants and products. Performing stoichiometric calculations is largely dependent upon these correct molar proportions.
