Can anyone help me get some notes for this? Especially more on atomic structure.
Much on the formula on for atomic structure. All the hydrogen thing here and there. Especially on the proton , neutron and electron. Help me out I got a short test coming up.
SHort summary
Proton, mass 1, charge +
Neuton, mass 1, charge 0
Electron, mass 1/1840, charge -
Ionic bond is formed by metal give one or more electron to non-metal
drawing is [metal](charge) [non metal](charge)
eg NaCl
Covalent bond is when two non metals share one or more electrons
drawing is the two or more non metals cme together
Kinetic theory, \
Just need to say particles lose energy/ gain energy to break intermolecular forces or form.
Solid, solid and neat rows, vibrating in fixed position
liquid, moving over each other sliding, disorder than solid
Gas, racing around at high speed no order
Photosynthesis
DEFINATION: It is the process whereby light energy absorbed by chlorophyll is transformed into chemical energy which is used to synthesize carbohydrates from water and carbohydrates. Water and carbon dioxide is the raw materials while oxygen is released in the process.
· Carbon dioxide + Water ------Light energy/ Chlorophyll ------> Glucose + Oxygen + Water
6CO2 + 12H20 à C6H12O6 + 6O2 + 6H2O
The glucose produced is either used immediately by cells during cellular respiration and cellular activities or converted into sucrose or starch in leaves, formation of amino acids, fats.
Photosynthesize is important as it make chemical energy available to animals, remove carbon dioxide and purify the air, stored energy in coal.
Limiting Reagents of photosynthesis are
· Light intensity
· Concentration of carbon dioxide
· Temperature
Aww, the H2 thing or what, is damm hard to remember! How!
Oh yes. I still remember got a circle thing. Like a damm drawing. Then got markings de. Circles and circles. Got markings for the specific element.
what H2????
