We’re being asked to determine which among the given statements Dalton's Atomic Theory states.
Matters are composed of small indestructible particles called atoms.
• because of this theory, it was determined that compounds are made up of atoms
• the atoms of same element are identical or similar
• in chemical reactions atoms rearranged themselves in different ways to undergo a chemical change
• but on the whole, the mass of all these atoms adds up to the same number
Ex. If you started with 10 g of reactants, these atoms rearrange themselves but the products formed would also total up to 10 g
Based on this, let’s analyze each statement given:
Dalton's Atomic Theory states:
A. that all elements have several isotopes
B. that matter is composed of small indestructible particles
C. that the properties of matter are determined by the properties of atoms
D. that the energy is neither created nor destroyed during a chemical reaction
E. that an atom is predominantly empty space
