What else can I help you with?
In certain mass of gas the number of atoms and the number of moleucules are equal How?
The gas has molecules that are single atoms, as do the noble gases.
Pairs of atoms that share equal number of electrons?
Atoms that share an equal number of electrons form covalent bonds. In these covalent bonds, each atom contributes the same number of electrons to the shared pair. This equal sharing of electrons results in stable molecules.
How many grams are in 8.2 x 10(22) atoms of N2I6?
To find the mass of 8.2 x 10²² atoms of N₂I₆, first determine the number of molecules, which is equal to the number of atoms divided by the number of atoms in one molecule of N₂I₆ (which contains 8 atoms). This gives approximately 1.025 x 10²² molecules. The molar mass of N₂I₆ is about 360.8 g/mol. Therefore, the mass in grams can be calculated by multiplying the number of molecules by the molar mass and dividing by Avogadro's number (6.022 x 10²³), resulting in approximately 57.4 grams.
What two quantities are conserved in redox equations?
there is a conservation of mass and charge.
Does one mole of copper contain an amount of copper atoms equal to avogadros number?
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.
What is the formula for chemical equations is balanced?
The number of reactants atoms must be equal to the number of products atoms.
Are molecules equal in a chemical equation?
No, molecules are not equal in a chemical equation. The number of atoms of each element on the reactant side must be equal to the number of atoms of the same element on the product side for the equation to be balanced.

What is meant by coefficient in relation to chemical equations?
In a chemical equation, a coefficient is a number placed in front of a chemical formula to balance the equation by ensuring that the number of atoms for each element is equal on both sides. It represents the ratio of moles or molecules involved in the reaction.
How many total molecules are there in 3be2br?
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
Why are chemical equations always balanced?
Chemical equations are always balanced to satisfy the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing equations ensures that the number of atoms of each element on the reactant side is equal to the number of atoms of the same element on the product side.
What are used to balance chemical equations?
Coefficients are used to balance chemical equations. These numbers are placed in front of the chemical formulas to ensure that the number of atoms on both sides of the equation are equal.
Why do chemical equations have the same number of atoms on each side?
Chemical equations follow the law of conservation of mass, which states that mass cannot be created or destroyed in a chemical reaction. As a result, the number of atoms on each side of the equation must be the same to maintain the balance of mass.
What is a balanced chemical equation Why should chemical equations be balanced?
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.
Why must chemical equations be balanced using coefficients?
The number of atoms in the reactant and products must be equal to obey the law of conservation of mass.
Are the number of atoms of bromine in 1 mol Br2 equal to avogadro's number?
No, the number of atoms in 1 mol of Br2 is equal to Avogadro's number multiplied by 2, because there are 2 atoms of bromine in each molecule of Br2. Avogadro's number represents the number of entities (atoms, molecules, etc.) in 1 mol of a substance.
