In a chemical equation, the number of atoms on each side must be balanced according to the Law of Conservation of Mass. For oxygen, the number of atoms can vary depending on the specific compound involved in the reaction. To determine the number of oxygen atoms on the left-hand side of an equation, you would need to look at the stoichiometry of the reaction being described.
In a chemical reaction, the total mass of the products is always equal to the total mass of the reactants. This is known as the law of conservation of mass. It means that no atoms are lost or gained during a chemical reaction, only rearranged to form new compounds.
No, it is not valid to conclude that the addition of a base would slow down a reaction.
The number of total carbon atoms in the product will depend on the specific molecules reacting. You would need to provide the chemical structures of the molecules involved in the reaction to determine the total number of carbon atoms in the product.
Electrons are most likely to be shared equally in nonpolar covalent bonds, where the atoms involved have similar electronegativities. This equal sharing occurs because neither atom has a strong pull on the shared electrons. Examples include diatomic molecules like oxygen (O2) and nitrogen (N2).
Mass is conserved in a closed system where no mass is entering or leaving. This principle is typically applicable in processes like chemical reactions, nuclear reactions, and physical transformations where mass is neither created nor destroyed, but simply converted into different forms.
No: That would violate the law of conservation of mass and require creation of new atoms, which no chemical reaction can achieve.
Nothing real - all measuring units are equally valid - BUT there would be a bit of human confusion.
Both terms are equally valid, which you would use would depend on the rest of the context.
According to Dalton's theory, chemical reactions involve the rearrangement of atoms and do not create or destroy atoms. Therefore, the transformation of CCl4 to CH4 would not be possible as it involves the addition of hydrogen atoms and the removal of chlorine atoms, which violates the law of conservation of atoms.
i would find conservation in the
a covalent bond is when two atoms share a pair of electrons
To balance the chemical equation, you would need to change it to: 2C2H4 -> 4C + 4H2. This balances the number of atoms of each element on both sides of the equation, ensuring the law of conservation of mass is obeyed.
In a non-polar covalent bond, where the two atoms share electrons equally, you would expect the shared electron pair to be equally distant from each atom. This occurs when the two atoms involved have the same or similar electronegativity values, resulting in a balanced sharing of electrons.
An unbalanced equation does not describe a reaction fully because the number of atoms of each element on the reactant side must equal the number of atoms of that element on the product side. Balancing the equation is important to ensure that the law of conservation of mass is obeyed, meaning atoms cannot be created or destroyed during a chemical reaction.
The Law of Conservation of Mass is valid in a closed system where no mass is entering or leaving. This law states that the total mass of the substances involved in a chemical reaction remains constant before and after the reaction has taken place.
No. There is no known way to make energy where there was none before. According to Nöther's Theorem, if Conservation of Energy wasn't valid, that would mean that the laws of physics changed over time!
