You are conducting a calorimetry experiment using a calorimeter with 500mL of water in its outer chamber to determine the enthalpy of reaction of a chemical reaction. The initial temperature of the water is 25°C. After the reaction, the temperature of the water is 43.6°C. Disregarding any heat loss to the walls of the container, calculate the ΔHr0. The specific heat of water is 4.18 J/(g•K).

ΔHr0=105.8kJ

ΔHr0=-140.0kJ

ΔHr0=45.3kJ

ΔHr0=38.9kJ

ΔHr0=25.7kJ

Ammonium perchlorate nh4clo4 is the solid rocket fuel used by the u.s. space shuttle. it reacts with itself to produce nitrogen gas n2 , chlorine gas cl2 , oxygen gas o2 , water h2o , and a great deal of energy. what mass of nitrogen gas is produced by the reaction of 2.1g of ammonium perchlorate?

Anyone who's in connections academy chemistry b have the factors that affect the rate of a reaction portfolio already done?

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
