Borek said:You start with 20g + 20g = 40g of reactants, is it possible to produce 180g of water?
Borek said:Sigh. I did my best to not use this term as a hint.
To balance this equation, you need to make sure that there are equal numbers of each type of atom on both sides of the arrow. In this case, there are 2 hydrogen atoms and 2 oxygen atoms on the left side, and only 2 hydrogen atoms and 1 oxygen atom on the right side. To balance the equation, you need to add a coefficient of 2 in front of the H2O on the right side, making the equation 2H2 + O2 -> 2H2O.
The purpose of balancing an equation is to accurately represent the reactants and products involved in a chemical reaction. A balanced equation ensures that the number and type of atoms are conserved throughout the reaction, and it allows for accurate calculations of substances involved.
No, you cannot change the subscripts in a chemical equation. Subscripts represent the number of each type of atom in a molecule and cannot be altered without changing the identity of the substance. Only coefficients can be added to balance an equation.
Yes, it is possible to have an unbalanced chemical equation. This means that the number of atoms on the reactant side does not equal the number of atoms on the product side. In order for a chemical equation to be considered balanced, it must have the same number of each type of atom on both sides of the arrow.
If adjusting coefficients does not balance the equation, there may be a mistake in the formula of one of the substances involved. Double check the formulas and make sure they are written correctly. If the equation still cannot be balanced, it is possible that the reaction is not feasible or that additional information is needed.
