What are the purposes of a chemical equation? check all that apply.
-to show how substances in a chemical reaction interact
-to shorten the explanation of a chemical reaction
-to make chemical reactions easier to recognize
-to keep track of atoms in a chemical reaction
-to show just the products of a chemical reaction

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

(**i would really appreciate if this was answered soon** ) which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

Carbon 14 is a naturally occurring stable
