Which coefficients correctly balance the formula equation CaO plus H2O CaOH2?
The coefficients that correctly balance the equation CaO + H2O -> Ca(OH)2 are: CaO + 2H2O -> Ca(OH)2. Two water molecules are needed to react with one calcium oxide molecule to form one calcium hydroxide molecule.
When the formula equation is correctly balanced the coefficient?
When the formula equation is correctly balanced, the coefficients represent the relative number of moles of each substance involved in the reaction. This ensures that the number of atoms on each side of the equation is the same, satisfying the law of conservation of mass.
What Never change a subscript to balance an equation?
Subscripts in a chemical formula represent the number of each atom present in a compound. Changing a subscript without changing the corresponding coefficients in a balanced chemical equation would alter the chemical formula and lead to an unbalanced equation. To balance the equation, adjust the coefficients in front of the compounds rather than changing the subscripts.
What is the name for the numbers that appear in the front of the chemical formula in a balanced equation?
The numbers that appear in front of the chemical formulas in a balanced equation are called coefficients. Coefficients are used to balance the equation by ensuring that the number of each type of atom is the same on both sides of the equation.
Is this true or false Subscripts can be changed in order to balance a chemical equation?
True. Subscripts represent the number of atoms of each element in a compound and changing them would change the chemical formula, possibly making it unbalanced in the equation. By adjusting the coefficients of the compounds involved in the reaction, the equation can be balanced without modifying the subscripts.
What coefficients correctly balance the formula equation Sb plus O2-Sb2O5?
The balanced equation is 4Sb + 5O2 → 2Sb2O5.
Which coefficients correctly balance the formula equation CaO plus H2O CaOH2?

What do coefficients in a chemical equation represent?
Coefficients in a chemical equation represent the number of units of the formula immediately following the coefficient that are involved in the balanced equation for the reaction.
Can you change the number of atoms in each molecule or formula in order to balance an equation?
Yes, you can change the coefficients in front of the molecules or formulas in a chemical equation to balance it. Balancing the equation ensures that the same number of each type of atom is present on both sides of the equation.

Subscripts can be changed in order to balance a chemical equation.?
false
When balancing a chemical equation can you adjust the script in a formula?
No. Never change the subscripts because then you are changing the formula of the substance to something else. You can only change the amount of a substance by adding a coefficient in front of the formula. If there is no coefficient, it is understood to be 1.
Why are the coefficients the only part of the chemical formula that can be changed in a chemical reaction?
Coefficients in a chemical formula represent the ratios of the number of molecules or atoms involved in a reaction. Changing coefficients alters the amount of each substance without changing the identity of the elements involved. The coefficients are adjusted to balance the reaction equation while keeping the overall chemical identities intact.
A number placed in front of a chemial formula in a chemical equation is called?
The number placed in front of a chemical formula in a chemical equation is called a coefficient. Coefficients are used to balance chemical equations by ensuring that the number of atoms of each element is the same on both sides of the equation.
