The answer is
b) electron
<span>We can relate the average speed
of the gas molecules by its kinetic energy. The kinetic energy is the work done
by the object due to its motion. It is represented by the formula of the half
the velocity squared multiply by the mass of the object. The absolute zero
theory is the assumption that at 0 Kelvin or -273.15 degrees Celsius, the gas
molecules stop moving. It is because the temperature is severely cold enough to
allow movement of the gas molecules. The gas molecule that is closest to the
absolute zero is in cylinder B because it moves so slow and its movement is
almost near to the absolute zero theory.</span>
<span>Answer: D. They all have the same number of electrons in the electron cloud</span>
A material is a mixture if it is not pure
Answer:
The answer is NH3 and CH3OH
Explanation:
The basic rule of a reaction is "like dissolves like" and for a homogenous mixture to form, there must be some common properties related to bonding.
1. KI and Hg
Normally mercury tends to form amalgam which is not a homogeneous solution.
2. LICL and C6H14
One is non polar and other is polar which makes the homogeneous reaction not possible.
3. C3H8 and C2H5OH
Both are miscible but will not develop homogeneous solution as propane is gas at normal temperature.
4. F2 and PF3
Flourine is highly electronegative and will repel fellow flourine making it not possible for homogeneous solution
5. NH3 and CH3OH
Both have same type of bonding and can react homogeneously.
