Grams of sodium and chlorine required to release energy of
Concept introduction:
When a chemical reaction occurs, it follows certain laws known as law of chemical combination. An important law of chemical combination is law of chemical conservation. Law of chemical conservation states that mass can neither be created nor be destroyed, it only changes its form. Mass lost if any in a reaction appears as energy in form of heat.

- Electrical energy is usually measured in kiloWatt-hours, kWh. A Watt is 1 joule per second. A kiloWatt is 1000 joules per second. An hour has 3600 seconds. Therefore 1 kWh = 3.6x106 joules. How many kWh are there in a meal that is 776 Cal, or nutritional calories? Just put in the number.
