Class 4 – Flammable Solids Division 4.1 – Flammable Solids are: • Wetted explosives that are Class 1 explosives when dry‚ that are sufficiently wetted to suppress explosive properties. • Self-reactive materials that are thermally unstable and can undergo strong exothermic decomposition even in the absence of oxygen. Readily combustible solids that can cause fire through friction‚ such as matches. Powdered‚ granular or pasty materials must be classified as Division 4.1 when the time of burning of

If you get a substance liquid or solid take it and try test try to figure it out what it is. When you bring it in have your other 5 buddies help test to see what it is. They should all try different chemicals from the other people. They see should all look at the chemical and physical appearance. My claim is the the mystery mixture was Citric acid‚ road salt‚ and baking soda. The reason I thought it was this mixture because of the physical and chemical appearance. I agree with baking soda road

* Cube In geometry‚ a cube is a three-dimensional solid object bounded by six square faces‚ facets or sides‚ with three meeting at each vertex. As the volume of a cube is the third power of its sides ‚ third powers are called cubes‚ by analogy with squares and second powers. A cube has the largest volume among cuboids (rectangular boxes) with a given surface area. Also‚ a cube has the largest volume among cuboids with the same total linear size (length+width+height). * Parts:

Peter the Apostle Peter the apostle was born BC 15 or so. Peter the apostle has been said to look like a very weak man. He was medium height‚ more so tall‚ and had very pale skin. Also‚ it has been said that Peter had a short‚ thick‚ curled beard‚ and very thin eyebrows‚ if not‚ no eyebrows at all. Another character trait of the Peter the apostle is that his eyes were almost all black‚ but had red marks due to weeping frequently. Peter the apostle‚ the most prominent of Jesus’ twelve disciples

AMERICAN INTERCONTINENTAL UNIVERSITY SUBJECT: Municipal Solid Waste Descriptions and Problems ABSTRACT: The Municipal Solid Waste is based in 4 main components that are recycling‚ composting‚ landfilling and waste-to-energy that is mainly done by burning the waste. This is known as materials of no longer being of value and is thrown out for disposal. Waste is handled and separated into different containers which are divided into solids‚ plastics and paper mainly. There are different types of

and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119.0C while the boiling point of liquid C was found to be 117C. The identity of solid C and

Liquids & Solids Pre Lab Questions: 3pts 1. What are the learning goals of this lab? The learning goal of this experiment is to view and experience the melting point and boiling point of different substances. 2. Why is acetamide not allowed in contact with your skin? What precautions does one have to take to work with this chemical? Acetamide is a carcinogen‚ which can cause cancer. Therefore‚ it should not be allowed to come in contact with a person’s skin. Any person working with this chemical

materials. Particles in each of the 3 states of matter behave differently. In a of particles. solid‚ the particles are very close and strongly attracted to each other. They can vibrate‚ but they cannot move from one place to another. They always stay in their positions‚ creating a defined shape and volume. In a liquid‚ the particles have weaker attraction and are not as close to each other as solids. They can move around in all directions so liquid does not have a defined shape‚ but their movements

Introduction Atoms‚ molecules‚ compounds and mixtures‚ although they may not seem it‚ are different. Atoms make up all of the above and elements. They are made an equal amount of protons and electrons. Molecules are made when two or more atoms connect chemically. Like molecules‚ compounds are made when two or more atoms connect chemically. Unlike molecules‚ the atoms need to be two or more different elements. Mixtures are made of two or more compounds or elements. Mixtures can look completely the same when
