Answer:
25 valence electrons.
Explanation:
Hello!
In this case, based on the attached picture, you can see that the chlorate ion has three oxygen atoms and one chlorine ion, whereas you can see there is a coordination bond (two arrows) from chlorine to oxygen which means that oxygen receives two electrons from chlorine in order to complete its octet and to allow chlorine to not exceed the octet. It means there is another oxygen completes its octet via the Cl=O bond and the the last oxygen is negatively charged because it is missing one bond to attain its octet even thought chlorine actually completes its octet.
Therefore, this ion has seven valence electrons from chlorine and 18 valence electrons from the three oxygen atoms, which means it has 25 valence electrons overall.
Best regards!
Answer: I think that trains move faster then cars! Buttt, The trains are much stronger and bigger, then cars or trucks. Even if they move slowly they can still crush something smaller then them.

Answer:
number of moles is inversely proportional to the Temperature
Explanation:
As we know
PV = nRT
where P is the pressure
V is the volume
n is the number of moles
R is the gas constant
and T is the temperature
If we see the equation, we can find that n is inversely proportional to the Temperature
Answer:
pH= 12.7
Explanation:
a)Keep an emergency kit and fresh water in your car in the event of _an unexpected event.
b) pOH= -log[OH-]
pOH= -log[5.00×10^-2]
pOH= 1.3
But pH+pOH= 14
pH= 14-pOH= 14-1.3
pH= 12.7
Melting points and boiling points of molecular compound are usually lower than ionic compounds. This is so as only a small amount of energy is required to overcome the weak intermolecular forces of attraction (Van de Waals forces) thus having lower m.p. and b.p.
Ionic compounds require a large amount of energy to overcome the strong electrostatic forces of attraction between the ions, hence having higher mp and bp
