What is the equation for the chemical change that produces water from two hydrogen molecules and one oxygen molecule?
The balanced chemical equation for the formation of water from two hydrogen molecules and one oxygen molecule is: 2H₂ + O₂ → 2H₂O.
Why is it essential to use balanced chemical equations when determining the quantity of a product fo?
Using a balanced chemical equation ensures that the mole ratio between reactants and products is accurate. This allows for precise calculations of the quantity of a product formed in a chemical reaction. Without a balanced equation, incorrect conclusions may be drawn regarding the amount of product produced.
What is the balance of chemical equation involve in evaporation?
Evaporation is not a chemical change and so there is no chemical equation.
A chemical reaction is balanced by changing?
To balance a chemical equation, you can change the coefficients (number of molecules). Remember: You cannot change the subscripts.When we balance an equation we change the number of atoms on one or both sides of the equation by means of simple mathematical calculation. That is, we change the number of molecules of one or more reactants or products. When the number of atoms of each element is equal on both sides of the equation, and cannot be reduced equally, the balancing process is complete.
What has to happen for a chemical equation to be balanced?
There has to be the same numbers and types of elements on both sides of the equation. This is accomplished by adding coefficients in front of the chemical formulas as needed. Never change a formula when balancing an equation.
Is every chemical change able to be written down as a chemical equation or only some of them?
yes and they are able to be balanced.
What is the relationship between coefficient and balance chemical equation?
Coefficients in a balanced chemical equation represent the relative amounts of reactants and products involved in a chemical reaction. By adjusting the coefficients, the equation can be balanced to ensure that the law of conservation of mass is upheld, meaning that the total number of atoms of each element are the same on both sides of the equation.
Is photosynthesis a chemcal change?
Yes, the balanced chemical equation is as follows: 6CO2 + 6H2O yeilds (or changes to) C6H12O2 + 6O2.
What can NEVER change these to make the equation balanced?
Changing subscripts in chemical formulas should never be done to balance a chemical equation because it changes the identity of the compounds involved. Instead, coefficients should be adjusted to balance the equation without altering the chemical formulas.
When you have a chemical change is the mass of what you start with less equal or greater than what you end with?
If the equation is balanced, the mass will be the same on each side of the equation. Matter cannot be created or destroyed.
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 is the balanced equation of mercuryII oxide HgO undergoes a chemical change to form mercury and oxygen?
the balanced equation of mercuryII oxide HgO undergoes a chemical change to form mercury and oxygen is given as .2HgO(s) --> 2Hg(l) + O2(g)The reaction is a redox reaction. Mercury (II) is reduced to zero charge. Oxygen is oxidized to zero charge.Molecule: HgO(s)
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 would you change to balance a chemical equation?
You can balance a chemical equation by adjusting the coefficients of the compounds involved. Start by balancing the atoms that appear in only one reactant and one product, then balance the atoms that appear in more than one compound. Finally, check that the equation is balanced by verifying that the number of each type of atom is the same on both sides of the equation.
When few pieces of marble is dropped in dilute hydrochloric acid the evolved gas passed through lime water what change would be observed in lime water so what will be the balanced chemical equation?
The chemical equation is:Ca(OH)2 + CO2 = CaCO3 + H2O
