Which of the following is true of balance equation?

Which of the following is true of balance equation?

Answer Expert Verified The right answer is There must be an equal number of atoms of each element on both sides of the equation. Balancing Equations is a part of Stoichiometry.

Is H2 O2 a chemical reaction?

When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed. An example of a simple chemical reaction is the breaking down of hydrogen peroxide molecules, each of which consists of two hydrogen atoms bonded to two oxygen atoms (H2O2).

Is H2 O2 -> H2O balanced?

The obtained result indicates that the oxygen atom is not equal on both sides. Thus the reaction is not balanced. The balanced reaction has the number of atoms involved in reaction in reactants as well as the product is equal.

What does 2H2O represent?

A coefficient multiplies the number of atoms of each element indicated in a chemical formula. Thus, 2H2O represents four H atoms and two O atoms. Now consider the number of oxygen atoms. This results in a correct chemical equation, or balanced formula equation.

What do the symbol 2H stand for?

H- Hydrogen atom. H2 – Dihydrogen or hydrogen gas. 2H- Two hyhdrogen atoms. 2H2 – Two dihydrogen molecule.

What is the difference between 2H and H _( 2 At least 2 dif?

H2 is molecular hydrogen.it is a molecule of hydrogen that consists of two hydrogen atoms bonded together by one single bond. 2H denotes two moles of elemental hydrogen.it should be noted that elemental hydrogen is not bonded to anything.

How do you find one mole of H2?

1 Answer. Mass of 1 mole of hydrogen atoms = Mass of 1 hydrogen atom×NA , where NA=L=6.0225×1023⋅mol−1 .

How many atoms are there in 1 mole of H2?

Thus we must consider the makeup of an H2 molecule, where we see that it is a diatomic molecule. Thus we must multiply 6.022 * 1023 by 2 to calculate the number of individual atoms present in 1 mole of H2. We find our answer to be 1
