Answer:
The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in
the products
Explanation:
For an equation to termed balance, the number of atoms of elements in the reactants must be equal to the number of atoms of the same element in the product.
The law of conservation of mass states that matter can neither be created nor destroyed during a chemical reaction but changes from one form to another. An unbalanced equation simply means that matter have been created or destroyed. This implies that balancing equation supports the laws of conservation of mass
Answer:
Average mass of 6 apple = 1 kg
Explanation:
Given:
Average mass of 5 dozen apple = 10 kg
Find:
Average mass of 6 apple
Computation:
Average mass of 6 apple = [Average mass of 1 apple] x [6 apple]
Average mass of 6 apple = [10/(12 x 5)] x [6]
Average mass of 6 apple = 1 kg
The valence shell of Oxygen contains 6 electrons. Therefore, for completion of the octet, each Oxygen atom requires two electrons. This means that each atom will supply two electrons in the bond. So the correct option is B.
You would expect a green to a blue color. Hope this helps :)
Answer:
The Sun
Explanation:
In the Solar System, the Sun is the primary object, containing over 99.9% of all the mass found in the Solar System, therefore it has the biggest gravitational pull, and it is the center of the Solar System. Subsequently, all planets, including Earth, revolve around it.
