reactants → products
Based on the Law of Conservation of Matter, describe the relationship between the mass of the reactants and the mass of the products.
A) The mass of the reactants equals the mass of the products.
B) The mass of the reactants is less than the mass of the products.
C) The mass of the reactants is greater than the mass of the products.
D) The mass of the products is always greater than the mass of the reactants.

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
