The mass of mercury (Hg) in the products formed as a result of the decomposition of 100g of mercury oxide is 93g (option A).
<h3>What is the law of conservation of matter?</h3>
The law of conservation of matter states that the mass of an element can neither be created nor destroyed.
The law further states that in a chemical reaction, the mass of the reactants must equal the mass of products.
According to this question, 100g of mercury oxide decomposes to produce oxygen of oxygen (O) and mercury (Hg) in a chemical reaction.
If 7g of oxygen (O) is produced in the reaction, the mass of mercury as the other product will be 100g - 7g = 93g.
Therefore, the mass of mercury (Hg) in the products formed as a result of the decomposition of 100g of mercury oxide is 93g.

HI There!
Which of the following is NOT the same as 13.6 milliliters?- 0.0136 dkL
- 0.0136 L
- 0.136 dL
Answer:<span>0.0136 dkL</span>
Answer:
[Ar] 3d10 4s1
Explanation:
The correct electronic configuration of copper is [Ar] 3d10 4s1
Copper has atomic number 29 and due to the stability of half filled or fully filled orbitals or shells, the electrons from the 4s jumps to the 3d and makes the 3d shell contain 10 electrons.
This is what I mean:
Cu = Ar 4s2 3d10 is the expected configuration of copper when we follow the principle of filling the various orbitals that is the s, p, d, f orbitals.
But because we write 3d before writing 4s, we have Ar 3d10 4s2. Instead of this configuration becoming the correct one, an electron from the 4s orbital jumps to the 3d orbital to complete the orbital giving the electrons in the 3d orbital 10.
So therefore the correct configuration is Ar 3d10 4s1
