Answer:
Should the government invest more money in nuclear energy than
in solar energy
Explanation:
This is because some people might think government should invest in nuclear energy while others might want the government to invest in solar energy.
Answer: The given reaction is a neutralization reaction.
Explanation:
When an acid chemically reacts with a base then it leads to the formation of salt and water.
For example, 
Here, KOH is a the base and 
is an acid which on chemical reaction with each other leads to the formation of salt 
and water 
.
Thus, we can conclude that the given reaction is a neutralization reaction.
Answer:
The wood
Explanation:
The block of wood shall float in the water while the iron key would sink due to the weight.
<h3>Answer:</h3>
Number of Protons = 6
Number of Electrons = 6
Number of Neutrons = 7
<h3>Explanation:</h3>
Number of Protons:
As the number of protons present in the nucleus are equal to the atomic number therefore, using periodic table one can easily find out the atomic number of C atom. Hence, C is present in group 14 and period 2 and having an atomic number of 6. Therefore, number of protons in C atom are 6.
Number of Electrons:
As shown in statement, C is not carrying any type of charge. It means this atom is neutral in nature. Which means, it is carrying the same number of electrons as the number of protons in order to give a neutral atom. Therefore, it contains 6 electrons.
Number of Neutrons:
Number of neutrons can be calculated using following formula,
No. of Neutrons = Atomic Mass - Number of Protons
As,
Atomic Mass = 13
So,
No. of Neutrons = 13 - 6
No. of Neutrons = 7
For a solid I would say something like aerogel would have a large volume but very little mass.
Let me know if this helped or not.
