Burning or combustion is a chemical reaction In combustion the fuel or the substance reacts with oxygen and release heat and light. It is an exothermic reaction. The given substances for combustion are: Selenium powder, Charcoal, sulfur, copper powder, a wooden splint and a piece of steel wool.The main component of charcoal is carbon. Burning of charcoal forms carbon dioxide and heat. The chemical reaction is as shown below: C(g)+O2(g)→CO2(g)+heat Burning of sulfur : Burning of sulfur forms sulfur dioxide which has pungent smell. S8 (s) +8 O2(g) → 8 SO2(g)Burning of copper: Copper burns and form copper oxide which is a black compound. 2Cu(s)+O2(g)→2CuO(s) Burning of selenium : Selenium burns in oxygen and form selenium dioxide which is a colorless salt. Se(s)+ O2(g)→SeO2(s) Burning of steel wool: The main component of steel wool is iron. Iron on combustion forms iron oxide which is a brown solid. 4Fe(s)+3O2(g)→2Fe2O3(s) Burning of wooden splint: Wood is mixture of hydro carbons. When it is burnt, it forms carbon dioxide and water vapor along with heat and light.

States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

Even though cement and bread are not substances, they can help you to understand these concepts: Whatever you do to volume affects mass the same way. Whatever you do to mass affects volume the same way. If you have half as much of a material, you would expect the volume of the material to also be half as much. If you have twice as much of the material, you would expect its volume to also be twice as much. Substances, which you know are always the same throughout, will follow this rule. This relationship between mass and volume will stay the same for any substance, no matter how much of that substance you can sample and measure in the classroom. Why is this principle about the relationship between mass and volume always true of substances, but not always true of mixtures?
CHEMISTRY Calculating Density Density is the compactness of matter. Density describes the quantity of matter (mass) per unit of volume (3-dimensional space). Density is calculated as the mass of the matter divided by volume. The symbol for density is Greek letter rho (p). The units for mass are in grams (g) and the units for volume is cubic centimeter (cm³). It should be noted that 1 cm³ is equal to 1 ml of volume. 1 cm³= 1 ml. The units for density are g/cm³. Part 1 Determine the density of the new liquid materials created in the Secret Density Research Laboratory. Type the value (no units) of the density into the boxes in the density column. Report density to the 2nd number after the decimal. Use a zero to the lef of the decimal for values less than 1.00. Examples: 2.35, 0.75, 1.90 Material name Harrisonite Waltonium Kellese Wheelernone Osborneum Popebrillium Mass (g) 430 590 260 m P=V 620 380 510 Volume (cm³) 537 454 236 364 633 340 Density (g/cm³) SAMSUNG
The laboratory compared the mass of the starting reactants and final products of the combustion reaction. A technician determined the mass of the firewood and oxygen reactants before burning to be 2.72 kg. After the firewood finished burning, the pile of cooled ash that remained had a mass of 0.095 kg. According to the law of conservation of mass, matter is neither created nor destroyed in a chemical reaction. Do the results of the technician’s combustion experiment contradict the law of conservation of mass?

To determine the concentration of iron in an unknown sample, a chemist analyzed the sample five times and obtained the following results: 410.34 ppm, 424.03 ppm, 340.49 ppm, 112.05 ppm, and 207.96 ppm. If the accepted literature value for the concentration of iron in this sample is 405.35 ppm, determine the percent error for this set of analyses.
