The period is the end of the sentence!!!
Answer:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Explanation:
How does the concept of conservation of mass apply to chemical reactions? the reactants and products have exactly the same atoms. the reactants and products have exactly the same molecules. the change in the amount of matter is equal to the change in energy.
can someone help me with my qustions?
The mass of electrons, protons, and neutrons:
electrons 9.10938291*10^-31 kg
protons 1.67262178*10^-27 kg
neutrons 1.6749*10^-27 kg
the mass of electrons is way smaller than both, the mass of protons and neutrons
therefore, 1) the mass of 2 electrons is the smallest
a because it was a combination of lots of subtances like CO2, oxygen, nitrogen,... and u cant see air so it is a homogenous mixture
U + 2I₂ → UI₄ uranium (IV) iodide
2U + 3I₂ → 2UI₃ uranium (III) iodide
2UI₄ ⇄ 2UI₃ + I₂
