within procedures: 1. Hydrogen G. When hydrogen gas comes in close contact with fire‚ it generates a loud noise similar to a popped piece of popcorn and it blows out the flame. 2. Oxygen B. When manganese reacts with H2O2 small bubbles form around the pieces of manganese and carbonates the whole solution. E. When I put the glowing toothpick in the oxygen gas it caused the toothpick to light up instantly for a short period and then made it glow brighter red. 3. Hydrogen

Chemistry Batteries [Chemistry HSC Course-1] What is an Anode? An anode is the negatively charged electrode of an electrical device but in this a primary cell‚ that supplies current. What is a Cathode? A cathode is the positively charged electrode of an electrical device which in this case is a primary cell‚ that supplies current. What is Current? A flow of current which results from the ordered directional movement of electrically charged particles. A current is the rate of flow of charge

MINERAL AND POWER RESOURCES India has a variety of mineral resources that play a very important role in the industrial development of the country. India has large deposits of Iron ore‚ manganese ore and bauxite ore. India has a virtual monopoly over mica. India is self-sufficient in coal but coking coal is limited. India has small deposits of zinc‚ copper‚ lead and gold. It lacks sulphur and is poor in the production of mineral oil and natural gas. We have small deposits of minerals required for

Jaycar Electronics Reference Data Sheet: BATTPRIM.PDF (1) PRIMARY CELLS & BATTERIES Many portable electrical and electronic devices are designed to be powered from batteries and in a lot of cases‚ from primary or non-rechargeable batteries. This is the familiar kind of battery which has a fixed amount of energy stored in it during manufacture‚ and once that energy has been used up the battery is simply thrown away and replaced. There are many different types of primary battery now available

The gas bubbles occurred faster in this mixture than it did with the diluted HCL and Zinc. The Manganese produced a fast reaction. 2F: Reason to fill test tube almost to 1 cm: 1- You want to obtain as much of the gas that you are trying to create as possible‚ with little oxygen 2- Contact of the chemicals and gases being produced with oxygen

THE USE OF BANANA PEEL TO WHITEN THE TEETH Abstract: Having a good smile with white teeth‚ become one of the things that people wanted to achieve nowadays. Base on our research some toothpaste aren’taffordable at the same time it is not effective ‚ now beacause of banana peel that contains some effective things to whiten and make our teeth stronger we have a idea that we can use this. Our Purpose is to make teeth stonger and whitener in affordable way for everyone. CHAPTER 1 Introduction
