The equation below shows the products formed when a solution of silver nitrate (AgNO3) reacts with a solution of sodium chloride
(NaCl).
AgNO3 + NaCl - NaNO3 + AGCI
(Reactants) – (Products)
In this equation, the total mass of the reactants is
equal to the mass of Ag CL.
less than the mass of AgCL
equal to the total mass of the products.
an the total mass of the products,

Occurs when an energy source transfers heat directly to another subject space; an example would be an object becoming warm by sitting in the sunshine

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
