Why is it important for an equation to be balanced? Answer. The chemical equation must be balanced in order to obey the law of conservation of mass. A chemical equation is said to be balanced when the number of different atoms of elements in the reactants side equals the number of atoms in the products side. Balancing chemical equations is a ...Proper chemical equations are balanced; the same number of each element’s atoms appears on each side of the equation. This page titled 5.2: Chemical Equations is shared under a CC BY-NC-SA 4.0 license and was authored, remixed, and/or curated by Anonymous via source content that was edited to the style and standards of the LibreTexts platform ...The balanced equation is: 2 Fe 2 O 3 + 3 C → 4 Fe + 3 CO 2. Both the left and right sides of the equation have 4 Fe, 6 O, and 3 C atoms. When you balance equations, it's a good idea to check your work by multiplying the subscript of each atom by the coefficient. When no subscript is cited, consider it to be 1.A photodecomposition reaction is a type of decomposition reaction in which the reactant is broken down to its constituents by absorbing energy from photons. An example of a photo decomposition reaction is the decomposition of ozone into dioxygen and an oxygen radical, as represented by the chemical equation provided below. O 3 + hν → O 2 + O.
Instructions To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored.Step 4: The new count for each atom and polyatomic ion becomes: Reactants Products 1Pbatom 1Pbatom 2NO − 3 ions 2NO − 3 ions 2Naatom 2Naatom 2Clatom 2Clatoms. Step 5: Think about the result. The equation is now balanced since there are equal numbers of atoms of each element on both sides of the equation.These quantitative relationships are known as the reaction’s stoichiometry, a term derived from the Greek words stoicheion (meaning “element”) and metron (meaning “measure”). In this module, the use of balanced chemical equations for various stoichiometric applications is explored. The general approach to using stoichiometric ... 10 examples of balanced chemical equations. Asked by ABHILASHA | 06 Apr, 2018, 10:07: AM Expert Answer 1. Zn + H 2 SO 4 → ZnSO 4 + H 2 ↑ . 2. AgNO 3 + NaCl ...
Example 7. Al 2 (CO 3) 3 + H 3 PO 4 ---> AlPO 4 + CO 2 + H 2 O. Answer ». There are two Al atoms on the left, but only one on the right, and the Al is in a single chemical species on each side, so we need 2AlPO4 to balance the Al. Al2(CO3)3 + H3PO4 -- …Balancing chemical equations involves the addition of stoichiometric coefficients to the reactants and products. This is important because a chemical equation must obey the law of conservation of mass and the law of constant proportions, i.e. the same number of atoms of each element must exist on the reactant side and the product side of the equation.Is a balance transfer a good idea?

Asked by ABHILASHA | 06 Apr, 2018, 10:07: AM Expert Answer 1. Zn + H 2 SO 4 → ZnSO 4 + H 2 ↑ . 2. AgNO 3 + NaCl ...Jul 25, 2023 · This means that you will need to balance the carbon atoms first. 5. Use a coefficient to balance the single carbon atom. Add a coefficient to the single carbon atom on the right of the equation to balance it with the 3 carbon atoms on the left of the equation. C 3 H 8 + O 2 --> H 2 O + 3 CO 2.
