Find all solutions of the congruence x2 ≡ 29 (mod 35). [Hint: Find the solutions of this congruence modulo 5, and modulo 7, and then use the Chinese remainder theorem.]

Chapter 2: Basic Chemistry and Biochemistry-Part 1 by Mehrnaz Ighani . Chemistry: the basis of all physiological reactions such as movement, digestion, metabolism, and etc. . Chemistry has 2 subdivisions: 1. Basic chemistry 2. Biochemistry . Matter: any object that has mass and occupies space Weight is mass+ the force of gravity . 3 states of matter: 1. Solid: defined shape and volume 2. Liquid: changeable shape but defined volume 3. Gas: changeable shape and volume . Energy: the capacity to do work or put matter into motion Doesn’t have mass, nor does it take up space The greater the work done, the more energy needed . Energy exists in 2 forms: 1. Kinetic energy (energy in action) 2. Potential energy (stored energy) Energy can be tran
