this is called having a balanced equation .....if both sides are not balanced u must correct it by changing the number of moles
Equations that show each side is equal as far as the number of atoms and molecules are called balanced equations. These equations are written representations of a chemical reaction.
That is known as a "balanced equation".
This is a correct balanced equation.
yes. That is absolutely true
This is a balanced equation.
balanced
The gas has molecules that are single atoms, as do the noble gases.
Molecules covalently bonded.
All atoms are built with a number of positive (protons) in their nuclei and a number of negative (electrons) in shells surrounding the nucleus. The number of protons and electrons are always equal meaning that the atom is electrically neutral ( the + and - charges balance out). The atoms of different elements all have a different number of positive (and therefore a balancing number of negative) components.
Yes, it does: 1mol Cu = 6.02*10^23 atoms (you can look at this as molecules to make it easier) 1mol H2 = 6.02*10^23 molecules - which is the same (dont get it confused, as H2 has 1.204*10^24 ATOMS, but the question expicitly asks for molecules) Yes, it does, though you might wish to say "atoms" to replace "molecules" as the question is written. A mole of any one thing will have an equal number of "particles" (atoms or molecules, depending on the substance) as a mole of something else. The mole (about 6.02 x 1023) is a large number, but one that is very effectively applied across a range of chemical activities to quantify some amount of a substance we might be using or investigating.
The number of reactants atoms must be equal to the number of products atoms.
The number of reactants atoms must be equal to the number of products atoms.
The total number of atoms of the reactants should be equal to the total number of atoms of the products. The total number of molecules of the reactants should be equal to the total numbers of molecules of the products
The gas has molecules that are single atoms, as do the noble gases.
Molecules covalently bonded.
For the same reason as a mathematical equation. The word equation is derived from EQUAL - so to be equal or balanced there has to be the same number of atoms on each side.
A balanced equation is when the amount of molecules reacting are equal to the amount of molecules being produced. Chemical equations must be balanced because no energy/mass is ever lost when a reaction takes place. This is because atoms are simply arranged.
The number of atoms in the reactant and products must be equal to obey the law of conservation of mass.
They are equal. Sometimes referred to as conservation of matter in a chemical reaction.
Yes, and even more than that: equal numbers of each kindof atoms.
Yes. 6.022 * 1023, the number of atoms or molecules in one mole, is also known as Avogadro's number.
There are several types of diatomic molecules, that is molecules formed by two atoms. Molecules formed by two identical atoms are frequent like gaseous hydrogen and oxygen (H2 and O2) while other molecules are made by different atoms like carbon monoxide (CO), nitric oxide (NO), and hydrogen chloride (HCl). It is to be noted that diatomic molecules have to be distinct by substances that are not formed by separated molecules, but where two atoms are present in an equal stoichiometric ratio. For example, solid NaCl (that is common cooking salt) is a crystal with a number of sodium atoms equal to the number of chloride atoms. In a crystal a regular disposition of atoms of different kinds is present where individual molecules cannot be insulated.
