Temperature measures the average kinetic (or motion) energy of the particles within a substance.
Answer:
2D structure is based on skeletal formula and
3D structure is based on ball and rod model
Explanation:
Please find the attached image of 2 D and 3 D structure of cis-4-nonene
The 2D structure of Cis-4 nonene resembles the shape of skeletal formula. Almost every organic molecule has notation of skeletal formula. Each carbon atom is connected to sufficient number of hydrogen atom so that the valence of each carbon atom is satisfied.
The carbon atom is located at the corner while the hydrogen atom are not indicated.
The three dimensional structure of Cis-4 nonene is based on stick and ball model where ball represents the various types of atoms and the rod length represents the bond. White ball represents the hydrogen atom and grey ball represents the carbon atoms.
Answer:
4.49dm3
Explanation:
2NH4Cl + Ca(OH)2 —> CaCl2 + 2NH3 + 2H2O
First, we need to convert 10g of ammonium chloride to mole. This is illustrated below:
Molar Mass of NH4Cl = 14 + (4x1) + 35.5 = 53.5g/mol
Mass of NH4Cl = 10g
Number of mole = Mass /Molar Mass
Number of mole of NH4Cl = 10/53.5 = 0.187mol
From the equation,
2moles of NH4Cl produced 2 moles of NH3.
Therefore, 0.187mol of NH4Cl will also produce 0.187mol of NH3
Now we can obtain the volume of NH3 produced by doing the following:
1mole of any gas occupy 24dm3
Therefore, 0.187mol of NH3 will occupy = 0.187 x 24 = 4.49dm3
Answer:
Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide. Al2O3 is an example of an amphoteric oxide.
