Answer No 1:
The chemical model that is flawed is:
4 C2 + S8 → 4 CS2
In this reaction, there are more number of carbon atoms in the reactants but lesser number of cabon atoms in the products. For a reaction to be balanced, there should be the same number of atoms in the reactants and products. Hence, option A does not represent a balanced equation.
<em>Answer No 2:</em>
The correct option is B) The model shows an unbalanced number of carbon atoms.
Consider the equation:
4 C2 + S8 → 4 CS2
In the reactants side of the equation, there are 8 atoms of carbon. In the products side there are only four carbon atoms. This shows that this equation in not balanced because of the carbon atoms.
The number of sulfur atoms remains same before the reaction and after the reaction. There are eight sulfur atoms in the reactants as well as products.
Answer:
[Og] 5g2 6f3 8s2 8p1
Explanation:
Unbihexium, or element 126 is a hypothetical chemical element, until the element is discovered, confirmed and a permanent number is decided. This element is expected to be a g-block superactinide and the eight element in the 8th period.
<span>c.Solids have a fixed shape, so they do not show random motion of particles.</span>
<span>Isotopes are atoms of a particular element that contain a different number of neutrons.
An atom or element have same number of protons and electrons, but when there is a change in number of neutrons, this is called isotope of that element. There are many elements that have their isotopes like carbon have three isotopes Carbon 12, 13 and 14.</span>
That law is known as Boyle's Law, "The volume of a given mass of a gas is inversely related to pressure when the temperature is constant"
