Please share some general question which we can ask to our teacher thanks. calculate the boiling point of a solution containing 0.456g of camphor (mol.wt.=152)dissolved in 31.4g of acetone (b.p=56.30deg C)if molal elevation constant is 1.72k/m. To give you an idea of how a ChemQuest is designed, examine the following excerpt from Chemistry Inquiry #8: Structure of Atoms. When these electrons return to their normal state, they release light energy. I love this !! I love to do experiment in chemistry .......... Marcy Goodfleisch from Planet Earth on June 23, 2012: Oh, yes, the image you've created in your mind probably doesn't nearly capture the mess. (NB: All numbers should be subscript). I always want to be perfect in chemistry but how can I learn it easily? Fast Fact: The word Atom comes from the Greek word for 'indivisible' - ironic, seeing as we know atoms are made of even smaller subatomic particles. click Fast Fact: All the letters of the alphabet are used in the Periodic Table, except J. The different colours are created using different chemicals, and one of two different chemical reactions: incandescence (light created through heat) and luminescence (light without heat). WOW, actually chemistry is very fun but needs alot of revision and praticals, I love chemistry but its need a lot of revision. I run a 'fireworks' science lesson usually once a year with my pupils to demonstrate how fireworks get their colour - it is very popular! They will only light if you strike them using the surface on the side of the box. Years ago, when I was having one of my first teenage parties, I tried to invent a punch recipe by putting Fizzies in 7-up. It was proposed in 1869 by Russian chemist, Dmitri Mendeleev. science fair project ideas answers amp tools. This is a process known as chemiluminescence: when the chemicals mix, electrons in the constituent atoms are raised to a higher energy level. function EJEJC_lc(th) { return false; } 1. The periodic table arranges the elements in two ways: In Japan, the word for Iron is tetsú; in France it is fer.To prevent communication problems, scientists use symbols which are the same all over the world. This is due to the substitution of sugar with the sweetener aspartame.

Home of High School Chemistry Guided Inquiry Lesson Plans. i love Chemistry even though is tough i wil keep on trying,so guys let us not give up thanx. They are not familiar with terms such as atomic number, mass number or isotopes. … Thanks for sharing! Ask now. The table shows the electrical charge and relative mass of the three major sub-atomic particles. You can print as many copies as you need. This hub examines the answers to some of the top chemistry-related science questions I have been asked by my students in our science lessons. From a slightly more down-to-earth perspective, everything from fireworks to cleaning products to paint is chemistry. About Chemistry Guided Inquiry | At this point, the students have not been taught about the structure of an atom. The glow in a glow stick is the result of two chemicals reacting together and giving off light energy in a process called chemiluminscence. Unlike previous attempts to organise the elements by properties, Mendeleev arranged the elements in order of the mass of their electrons. answer keys. Chemistry is my favourite subject and things related to chemistry is the most favourite one ! a FEW lectures and you have a whole year of chemistry! Bunsen Burners, test-tubes filled with brightly coloured fluids, goggles and strange smells; this is the world of chemistry - at least to someone starting high school!

You can figure out what happened after that . Ozone is one of those weird chemicals - when produced at sea level (usually in car engines) it is highly toxic, but without it life as we know it could not exist.
