Answer:
Thus, the radius of the helium atom in nanometers is - 0.031 nm
Explanation:
Given that:-
The radius of the helium atom = 31 pm
Considering the conversion of length in pm to the length in nm as:-
1 pm = 0.001 nm
So,
Applying the above conversion factor in the radius of helium atom as:-
Radius = nm = 0.031 nm
<u>Thus, the radius of the helium atom in nanometers is - 0.031 nm</u>
Answer: It's C
Explanation:
A solution is defined as a homogeneous mixture in which solute particles are evenly distributed into the solvent.
A solution is a clear solution whose particles cannot be separated out as they are all present in same state.
On the other hand, a mixture in which particles are unevenly distributed into the solvent is known as a heterogeneous mixture.
For example, sand in water is a heterogeneous mixture.
Particles of a heterogeneous mixture can be separated out generally through filtration. This is because these particles are not present in same state.
Thus, we can conclude that the statement a mixture having a uniform composition where the components can't be seen separately and all components are in the same state, best describes a solution.
You can explain it by doing an experiment based or about density column.
Answer:
liquid
Explanation:
the state of matter is liquid
Yes, The car will accelerate if its velocity changes in magnitude, in direction, or both. If a car is traveling at a constant speed of 35 m/s, it can be accelerating if its direction of motion is changing.
