VALENCY Valency can be defined as the combining capacity of an element.The electrons present in the outermostmost shell of an atom are known as valence electrons and they determine the valency.The valence electrons take part in chemical reaction and they determine the chemical properties of the elements.Let us take an example‚ Theatomic number of carbon is 6 Its configuration is =2‚4 It means valency of carbon is 4. In chemistry‚ valence‚ also known as valency or valence number‚ is the number

Profile Johann is a 66 year old lady living in rural ireland. She lives by herself in a small cottage in the centre of her village. She is within walking distance to two grocery shops‚ a national school‚ a church and two pubs. Her daughter lives on the other side of the village which is within walking distance also. Johann has two daughters and one son that she sees regularly and one son from a previous relationship that she sees occasionally. She was diagnosed with bi-polar (manic) depression at

necessary for our bodies to make ATP (adenosine triphosphate)‚ which is the energy source used by our cells. Phosphate Analysis 11. After heating‚ a cloudy white solution with white precipitate was the result. 12. Phosphorus forms a wide range of sulfides‚ where phosphorus can be P(V)‚ P(III) or other oxidation states. Most famous is the three-fold symmetric P4S3 used in strike-anywhere matches. P4S10and P4O10 has analogous structures. 13. ATP‚ or Adenosine Triphosphate‚ is a molecule found

because it will have more gravitational potential energy the higher dropped from. As it is dropped the ball will have kinetic energy‚ and then when it hits the ground changes to heat and sound energy‚ and kinetic as it rebounds back up. The higher up the ball is dropped from the more gravitational potential‚ more kinetic energy on the way down and therefore more sound heat and kinetic energy when hitting the ground. The ball will bounce higher the higher dropped from as the energy has to go somewhere

Potential energy is the energy of position and kinetic energy is the energy of motion. In order for the ramp to be successful‚ the ramp had to have the right amount of potential and kinetic energy. If you have too much potential energy than the marble would have too much kinetic energy and the marble would not land inside of the target cup‚ it will go right over the top of it. If you have too little potential energy then the marble will not have enough kinetic energy and the marble will not land inside

In this experiment‚ one of the big is osmosis‚ and how it had the overall impact in this excitement a little on osmosis. Osmosis takes place when two solutions of different concentrations are separated by a semi-permeable membrane in which the solvent can pass through but not the solute. In our experiment‚ we used a sucrose solution that will be a hypotonic concentration of solute. This tells us that the solution has a lower concentration of water than does the cells. Therefore‚ due to osmosis‚ the

Proportions of Fertilizers: Fertilizers typically provide‚ in varying proportions: six macronutrients: nitrogen (N)‚ phosphorus (P)‚ potassium (K)‚ calcium (Ca)‚ magnesium (Mg)‚ and sulfur (S); seven micronutrients: boron (B)‚ chlorine (Cl)‚ copper (Cu)‚ iron (Fe)‚ manganese (Mn)‚ molybdenum (Mo)‚ and zinc (Zn).
