Answer : Isopropanol molecules ( C₃H₈O) are the major species present when dissolved in water.
Explanation :
Compounds are of 2 types.
1) Ionic compounds : These are formed by the transfer of electrons from a metal to a non metal.
When ionic compounds are dissolved in water, they get separated into ions.
Therefore the major species present in case of an ionic compound are ions.
2) Molecular (Covalent) compounds: These are formed by sharing of electrons among 2 or more non metals.
Covalent compounds are further categorized as
a) Polar covalent : Polar covalent compounds partially dissociate to form ions.
Therefore the major species in case of polar covalent compounds are the undissociated molecules and ions.
b) Non polar covalent : Non polar covalent compounds are unable to dissociate and they remain in molecular form when dissolved. So the major species in case of a non polar compound are undissociated molecules only.
Isopropanol is a non polar covalent compound. As discussed above it will have undissociated isopropanol molecules as major species.
Hence Isopropanol molecules ( C₃H₈O) are the major species present when dissolved in water.
Answer:
True
Explanation:
This means the fuel is highly flammable hence it has a low ignition temperature. This, therefore, means it burns fast without putting in a lot of energy to ignite it. Even in cars, therefore, the compression ratios, in engines using these of these fuels, is lesser.
But what is the width of the molecule
Answer:
<h2>0.14 kg</h2>
Explanation:
The mass of the ball can be found by using the formula

v is the velocity
k is the kinetic energy
From the question we have

We have the final answer as
<h3>0.14 kg</h3>
Hope this helps you
