Answer:
Sorry how no this equation guys
Answer:
Structural
Explanation:
Isomerism is the existence of two or more compounds with the same molecular formula but different molecular structures due to the difference in the arrangement of atoms or spatial orientation of atoms.
Isomers have the same molecular formula but differs in their structural arrangement.
In organic chemistry, Isomerism can orginate from different arrangement of atoms.
It can be carbon chain length known as chain isomerism. Here, the carbon length is changed and arranged in different ways.
We can also have position isomerism which entails the position of the functional group in the structure.
It can also be functional group isomerism which deals with the possible arrangement of the group on the chain.
Answer: B
Explanation:
The rate law is the mathematical equation that describes how reactant concentration changes as a function of time. A law such as "Rate = k*[A]*[B]" means that, for each liter-equivalent of the reactant(s) A, there are k liters of reactant B. The law also dictates the molarity (and thus partial pressure) for each component in solution.
Answer:
pH = 5.24
Explanation:
Mixture of acetic acid with acetate ion is a buffer (Mixture of a weak acid with its conjugate base). The pH of a buffer can be determined using Henderson-Hasselbalch equation:
pH = pKa + log₁₀ [A⁻] / [HA]
<em>Where pKa is -log Ka = 4.74; [A⁻] is the concentration of conjugate base (Acetate ion) and [HA] is molar concentration of the weak acid.</em>
Concentration of the acetic acid in the 100mL≡0.1L (76mL + 24mL) solution is:
[HA] = 0.024L ₓ (1mol / L) / 0.1L = 0.24M
[A⁻] = 0.076L ₓ (1mol / L) / 0.1L = 0.76M
Replacing in H-H equation:
pH = 4.74 + log₁₀ [0.76M] / [0.24M]
<h3>pH = 5.24</h3>

Answer:
Stannic fluoride, SnF4
Explanation:
The chemical formula of Barium nitride is Ba(NO3)2.
The chemical formula of Cobaltous chloride is COCl2.
The chemical formula of Sodium Oxide is Na2O.
So the correct one is stannic fluoride, SnF4.
