Open your text book and read the assignment. You will not learn by asking others for the answer. If you are studying to be in medicine, you do your future patients a dis-service by asking others for the answer.
By separating the compounds into separate dots on the plate. It is pure if the only dot showing up is that of the tested product
The potential energy of the molecules change during a reaction.
The formula for methane is CH4, showing that each molecule contains exactly 5 atoms. Therefore, the number of atoms in 0.650 ml is 5 X 0.650 X Avogadro's Number, or about 1.96 X 1024 atoms, to the justified number of significant digits.
The Lewis structure of compounds uses dots and bands to show bonds and molecules. It is the standard model used showing covalence and ionic bonds for compounds.
In case of trivalent N, the molecules are pyraMIDAL in nature.one of the orbitals is occupied by the lone pair of electrons.now, due to vibration in the molecule along the axis perpendicular to the bond axis ,the molecules are inverted and the two forms remain in equilibrium state .these two forms are non superimposablemirror images(showing enantiomerism) --- this phenomenon of trivalent n compounds are known as INVERTOMERISM
Water molecules are associated by hydrogen bods.
glucose + esculetin??
because he saw a film at Devon showing military skiing
The Lewis structure of a carbon atom, showing its four valence electrons.
They evolved over thousands of years but really started showing up as a separate item in the 1700's.
The formula of hydroxylamine is HONH2, showing three hydrogen atom per molecule. Therefore, in 2 molecules there will be six hydrogen atoms.
A Collision model is a model of the rate of a reaction showing how the rate is proportional to the number of collisions of reactant molecules.
1. Place a small amount of glucose with some Benedict's solution in a test tube 2. Heat this by putting the test tube in a beaker of boiling water. 3. Once you've done this, the solution will turn from clear blue to cloudy green before changing again in colour to yellow and then lastly a precipate red copper (1) oxide will be deposited.
The little circles represent the gas molecules and the arrows denote the direction of their motion.
A pie graph represent data as a part of a whole, showing the separate portions of the data in accordance to the whole.
Amerigo Vespucci published a map showing the Americas as a separate set of continents, not as part of Asia. America was named in his honor.
I can pull up the small screen but it only shows whatever the large screen is showing
