If it is three moles of NaOH i.e 3 NaOH
The number of atoms in each mole = 3 moles atoms
so total moles of atom = 9 moles of atom
in each mole of atoms = 6.023 X 10^23 atoms
so total atoms in three moles of NaOH = 9 X 6.023 X 10^23 atoms
= 5.4207 X 10^24 atoms
First quarter moon
Gibbous moon
Third quarter moon
Any help is greatly appreciated!! :)
Answer:
The answer is: Can be first quarter moon or third quarter moon.
Explanation:
At first quarter moon and at third quarter moon we can see exactly half of the moon lit up. But, it depends on the place in the planet where you are, which side of the moon you see lit up in which stage of the moon. In the north, the left part of the moon is lit up in third quarter, while in the south is the righ part. An the same for the first quarter, where de right half of the moon is lit up for the north and for the south it is the left. So, the real answer is: For the north part of the world, it will be at third quarter, and for the south part, it will be at first quarter.
B. Carbon
C. Methane
D. Water
Carbon is the substance can not be decomposed by a chemical change. Therefore, option B is correct.
A chemical change is the transformation of one material into another, the formation of new materials with different properties, and the formation of one or more new substances. It occurs when one substance reacts with another to form a new substance.
Carbon and water Although carbon dioxide and carbonic acid are simpler compounds, they are still compounds. As a result, they can decompose and leave us with the basic elements' hydrogen, oxygen, and carbon. Compounds degrade due to chemical changes.
Elements are pure substances that cannot be broken down using conventional chemical methods such as heating, electrolysis, or reaction. Elements include gold, carbon, silver, and oxygen.
Thus, option B is correct.

(2) The rate of the forward reaction must equal the rate of the reverse reaction.
(3) The concentration of the reactants must equal the concentration of the products.
(4) The potential energy of the reactants must equal the potential energy of the products.
Answer: The correct answer is Option 2.
Explanation:
Reversible reaction is defined as the reaction in which the products formed react together to give the reactants back. For general reversible chemical equation:
At equilibrium, the rate of forward reaction is equal to the rate of backward reaction.
Rate of forward reaction:
Rate of backward reaction:
At equilibrium, =
Thus, the correct answer is Option 2.
