How do you balance C2 H6O -- CO2 plus H2O?
To balance the equation C2H6O -> CO2 + H2O, you need to add a coefficient of 3 in front of CO2 and 4 in front of H2O to balance the number of carbon and hydrogen atoms, while keeping the number of oxygen atoms equal on both sides. The balanced equation is: C2H6O -> 2CO2 + 3H2O.
When a chemical reaction is balanced what number appears?
You think probable to the number of molecules or atoms.
What is the name for the 2 in front of 2H2O?
The number 2 IN FRONT is called a coefficient, and it tells you that there are two water molecules.The number BETWEEN the "H" and the "O" tells you that in one single molecule of water, it is made of 2 atoms of hydrogen, and 1 atom of oxygen.For example, if hydrogen gas (H2) is combined oxygen (O2), water (H2O) is formed. Because the formula is H2, two little "2" tells us that hydrogen gas is composed of 2 atoms of hydrogen. Same with oxygen -- O2 is made of two atoms of oxygen. The balanced equation for the reaction to form water is: 2H2 + O2 ---> 2H2OWhat the numbers in front of the molecules mean is that 2 molecules of hydrogen combine with one molecule of oxygen to form 2 molecules of water.See the Related Questions about balanced equations and stoichiometry for more about how coefficients are used and what they tell us about a reaction.
What is the large number that appears in front of a chemical formula called?
The large number that appears in front of a chemical formula is called a coefficient. It represents the number of molecules or units of that particular substance in the reaction.
The number placed in front of a chemical symbol or formula is called?
The number placed in front of a chemical symbol or formula is called a coefficient. It represents the number of molecules or formula units in a chemical reaction.
What is the name of a number in front of a chemical formula in an equation called?
This is the number of molecules or atoms involved in the reaction.
How can I tell if a chemical reaction is balanced or not balanced?
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.

What is the number in front of a chemical formula called-?
atomic number or atomic weight. Subscript: atomic number, superscript: atomic weight: 94Pu239 or 239Pu
What is a coefficient in physical science?
a coefficent in physical science means:a number in front of a chemical formula in an equation that indicates how many molecules or atoms of each reactant and product that are involved in a reaction
What does the final result of balancing a reaction look like?
The final result of balancing a chemical reaction should show the same number of atoms of each element on both sides of the reaction equation. This ensures that mass is conserved in the reaction. The coefficients in front of each compound indicate the ratio of reactants and products, with the smallest whole number coefficients possible.
What gets written in to a chemical reaction when it is balanced?
Coefficients (numbers) are placed in front of the reactants and products in the chemical reaction to satisfy the law of conservation of mass and ensure that the number of atoms for each element is the same on both sides of the reaction.
What is the number of water molecules in the balanced equation?
The number of water molecules in a balanced equation depends on the specific reaction being considered. The coefficient in front of water (H2O) in the balanced equation indicates how many molecules of water are involved in the reaction.
