Answer:Hydrogen is placed such because it exhibits some similar characteristics of both group1 and group VII elements.
Explanation:
The reason why hydrogen is similar to group 1 metals:
#It has same valence electron and inorder achieve octet state it can lose that electron and forms H+ ion
#It acts as a good reducing agent similar to group1 metals
#It can also halides
Similarity to halogens:
#hydrogen can also gain one electron to gain noble gas configuration. It can combine with other non metals to form molecules with covalent bonding.
#It exists as diatomin molecule,H2
#Have the same electronegativity nature
#its reaction with other metal
it's Lithium or Li

Explanation:
<u>Specific Heat of water</u> = 4.186 J/(g-C)
J/(g-C) multiplied by g and C results in J
4.186 * 540 * (95-32) = <u>142 407 .72 J</u>
<u>Answer:</u> The correct answer is False.
<u>Explanation:</u>
A magnet has two poles defined as a north pole and a south pole.
When two same poles come closer to each other, they tend to repel each other and when two opposite poles come closer to each other, they tend to attract each other.
So, when north pole comes near to another north pole, they will repel each other while when north pole comes near to the south pole, they attract each other.
Hence, the above statement is False.
