None of the given statements are completely true.
<u>Explanation</u>:
Family or groups in "periodic table" are 18 in number which represents column in table. As we go down in a family or group in the "periodic table"-the atom size become bigger and bigger. Non-Metals are less reactive which mostly lie in p-block. "Metals" are ""ore reactive" in "s-block". The atom’s valence electrons remain same for example when we go down in alkali metals in s-block the valence electron is one only and in alkaline earth metals its two only.
Answer:
The correct answer is "0.31 M".
Explanation:
Given,
Volume,
Molarity,
Let the M₂ be "x".
By using the dilution formula, we get
⇒
then,

A hot metal with a low heat capacity will raise the final temperature of water more than a hot metal with high heat capacity.
<h3>Heat capacity</h3>
It is the amount of heat required to change the temperature of a substance by just a unit.
Substances that heat up quickly are said to have low heat capacities while those that take time to heat up are said to have high heat capacities.
Substances with low heat capacity also release their thermal energy quicker than those with high heat capacity.
Thus, a hot metal with low heat capacity will readily transfer its thermal energy to water than a hot metal with high heat capacity.
