Answer:
Start by balancing the carbon atoms:
There is one carbon atom on each side of the equation, so carbon is already balanced.
Next, balance the hydrogen atoms:
There are four hydrogen atoms on the left (in CH4), so we need four HCl molecules on the right to balance the hydrogen atoms. The equation now becomes:
CH4 + Cl2 → CCl4 + 4HCl
Now, balance the chlorine atoms:
There are two chlorine atoms on the right (in CCl4), so we need two Cl2 molecules on the left to balance the chlorine atoms. The equation now becomes:
CH4 +
Explanation:
Even though the number of atoms on the left side (reactants) is 7 and on the right side (products) is 9, the law of conservation of matter is still upheld. This is because we need to consider the coefficients (the numbers in front of each compound) to account for the total mass. When you balance the equation and adjust the coefficients, you'll find that the total number of atoms remains the same on both sides, satisfying the law of conservation of matter.

Answer: Option (a) is the correct answer.
Explanation:
A metal is a substance which loses electron(s) in order to attain stability.
For example, sodium is an alkali metals with atomic number 11 and its electronic distribution is 2, 8, 1.
So, in order to attain stability sodium will readily lose 1 electron and forms ion.
Whereas non-metals are the substances which gain electron(s) in order to attain stability.
For example, atomic number of carbon is 6 and its electronic configuration is 2, 4.
To attain stability a carbon atom shares it 4 valence electrons with another atom.
Thus, we can conclude that out of the given options, Na is a metal.
