Answer:
Enantiomers are the non-superimposable mirror images of each other.
Diastereomers are the stereisomers that are not a reflection or mirror images of each other.
Explanation:
Stereoisomers are the chemical molecules having the same molecular formula and bond connectivity but different arrangement of atoms in space.
Stereoisomers are of two types: Enantiomers and Diastereomers
Enantiomers are the non-superimposable mirror images of each other. Enantiomers are also called optical isomers.
Diastereomers are the stereisomers that are not a reflection or mirror images of each other. Diastereomers include E-Z isomers, cis–trans isomers, meso compounds, non-enantiomeric optical isomers.
Answer:
4.704J
Explanation:
The following data were obtained from the question:
m = 0.080kg
h = 6.0m
g = 9.8m/s^2
P.E =?
P.E = mgh
P.E = 0.08 x 9.8 x 6
P.E = 4.704J
Therefore, the potential energy of the robin is 4.704J
I think the answer would be the last option. The difference between the energy transformations in power plants and dams would be that dams are the ones who uses mechanical energy to produce electricity. It uses turbines to convert mechanical to electrical.
Answer: 125 g
Explanation:
To calculate the moles :
![\text{Moles of} B_2H_6=\frac{36.1g}{17}=1.30moles](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%7D%20B_2H_6%3D%5Cfrac%7B36.1g%7D%7B17%7D%3D1.30moles)
The balanced reaction is:
According to stoichiometry :
1 mole of
require = 3 moles of ![O_2](https://tex.z-dn.net/?f=O_2)
Thus 1.30 moles of
will require=
of ![O_2](https://tex.z-dn.net/?f=O_2)
Mass of ![O_2=moles\times {\text {Molar mass}}=3.90moles\times 32g/mol=125g](https://tex.z-dn.net/?f=O_2%3Dmoles%5Ctimes%20%7B%5Ctext%20%7BMolar%20mass%7D%7D%3D3.90moles%5Ctimes%2032g%2Fmol%3D125g)
Thus 125 g of
will be needed to burn 36.1 g of ![B_2H_6](https://tex.z-dn.net/?f=B_2H_6)
