Answer:
2 - Bromo - 2 - Methyl Propane
Explanation:
The structure of the compound is given in the attached image as;
The longest chain is; CH₃--C--CH₃ = 3 carbon atoms = Propane
It has two substituents on the middle carbon = CH₃ and Br = 2 - Bromo- and 2 - Methyl
The IUPAC name is given as; 2 - Bromo - 2 - Methyl Propane
D= mass/volume so it's 100/68 which equals 1.47cm3
(NH4)2CO3..... I just learned this so that why i know.
Answer:
7.14 × 10^(-58) m
Explanation:
We are given;
Energy; E = 2.78 x 10^(32) J
Formula to find this energy is;
E = hc/λ
Where;
E is energy
h is Planck's constant with a constant value of 6.62 × 10^(-34) J/s
c is speed of light with a constant value of 3 × 10^(8) m/s
λ is wavelength
Making λ the subject, we have;
λ = hc/E
λ = (6.62 × 10^(-34) × 3 × 10^(8))/(2.78 x 10^(32))
λ = 7.14 × 10^(-58) m
A substance in the air which can change the surface of limestone would be oxygen, O2.
