Answer:
is is the process of combination of two or more small nuclei to form large nucleus having large amount of energy
Answer:
Increases
Explanation:
Frequency and wavelength of lights are inversely proportional to each other.
The wave of light having highest frequency have shortest wavelength and the light with the shortest frequency having highest wavelength.
Formula:
Speed of light = wavelength × frequency
c = λ × f
λ = c/f
This formula shows that both are inversely related to each other.
The speed of light is 3×10⁸ m/s
Frequency is taken in Hz.
It is the number of oscillations, wave of light make in one second.
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
Hydrocarbons are chains of C and H. C and H are held together by covalent bonds.
hydrocarbons are of three main types
alkanes - only single bonds between C atoms
alkenes - double bonds between C atoms present
alkynes - triples bonds between C atoms present
saturated hydrocarbons definition is when there are only single bonds present
from the given compounds
propane - only single bonds
propene - double bond
propyne - triple bond
propanal - double bond between C and O
only compound with single bonds is propane
answer is propane
The answer is chemical change
That is exploding of potassium metal when placed in water is chemical change.
When potassium is dropped into a beaker full of water then potassium moves about rapidly and then ignites within seconds, that is the metal is gone and all activity ceases.
So it an example of chemical change.
The reaction of potassium with water is as follows:
2K + 2H₂O ---->2KOH + H₂
Answer:
a) unstable
b) unstable
c) unstable
d) Stable
Explanation:
a)
The given isotope , atomic number is greater than 83.(84>83).
Therefore, it is unstable.
b)
The given isotope has even number of protons(15) and neutrons(15).
Therefore, it is unstable.
c)
The given isotope has even number of protons(15).
Therefore, it is unstable.
d)
The given isotope have even number of neutrons ( 68) an d the proton ratio is .It is more than 1.25.
Therefore, it is stable.
