You are conducting a calorimetry experiment using a calorimeter with 500 ml of water in its outer chamber to determine the enthalpy of reaction of a chemical reaction. The initial temperature of the water was 25 °C. After the reaction, the temperature of the water was 57.4 °C. Disregarding any heat loss to the walls of the container, calculate the H1). (The
specific heat of the water is 4.18 J/(8.K).

A 16.2kj

B 2.09kj

C 0.14kj

D 67.7kj

E 135.4kj

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
