No, it is not true; the law remain valid.
No. That would violate the Newtonian principle of Conservation of Mass.
Why should it violate it? Atoms are simply rearranged. No new atoms are created, no atoms are destroyed. The rust will have more mass than the original iron (or whatever metal is rusting), but that's because oxygen atoms from the atmosphere are added. Add: This does not violate the law of conservation of mass, because the mass of the rust is the combined mass of the iron and the oxygen in the atmosphere that reacted to form the rust.
Not quite sure what you mean; let's just say that living systems don't require any extraordinary efforts to conserve energy and mass, because that's what they do naturally, i.e., "be conserved". There is no known way to violate conservation of energy or mass.
This would violate the law of conservation of matter/mass, which states that in a closed system, mass is constant. This means that matter can neither be created nor destroyed in a chemical reaction. In other words, the mass of the products equals the mass of the reactants.
Transformation of energy does follow the conservation of mass and energy. When a body gains potential energy, it loses kinetic energy and viceversa. Therefore total energy always remains constant.
No. That would violate the Newtonian principle of Conservation of Mass.
no Nothing violates that law.
No, fusion does not violate the law of conservation of matter. In fusion reactions, the total mass of the reactants is equal to the total mass of the products, as mass is converted into energy according to Einstein's famous equation, Emc2.
no Nothing violates that law.
No, it does not violate the law of conservation of mass. The reason for this is that the decrease in mass of the compound can be found in the mass of the water that was lost upon heating. Thus, total mass remains constant.
No, nothing can violate the law of conservation of energy, it's a law! Energy can convert to mass, and mass can convert to energy, but the overall total of mass and energy in the universe is constant.

it is very simple actually because believe it or not rust has its own mass and after the nail rusts its mass increases
Left intact the rusted bolt because it has the added mass of the Oxygen. Once cleaned up it will be lighter because it has lost mass in the form of iron atoms in the Iron Oxide molecules.
No: That would violate the law of conservation of mass and require creation of new atoms, which no chemical reaction can achieve.
When a nail rusts, it undergoes a chemical reaction with oxygen in the air to form iron oxide (rust). This process adds additional mass to the nail in the form of the iron oxide. Therefore, the mass of the rusted nail is greater than the mass of the nail before it rusted.
No, because the principle of conservation of matter states that during a chemical reaction, matter is neither created nor destroyed. The total mass of reactants MUST equal the total mass of products.
