Answer:
The value of the activation energy is 240.96 kJ/mol.
Explanation:
According to the Arrhenius equation,
The graph between log(k) and (1/T) will give straight line with negative slope along with the intercept corresponding to the value of A.
Slope f the line =
The slope of the line :
The value of the activation energy is 240.96 kJ/mol.
Answer:
no idea even no idea dont know the idea
halogens
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
Answer:
CN⁻(aq) + H⁺(aq) ⇒ HCN(aq)
Explanation:
Let's consider the following molecular equation.
NaCN(aq) + HI(aq) ⇒ NaI(aq) + HCN(aq)
HI is a strong electrolyte so it exists mostly in the ionic form. HCN is a weak electrolyte so it exists mostly in the molecular form.
The full ionic equation includes all the ions and the molecular species.
Na⁺(aq) + CN⁻(aq) + H⁺(aq) + I⁻(aq) ⇒ Na⁺(aq) + I⁻(aq) + HCN(aq)
The net ionic equation includes only the ions that participate in the reaction and the molecular species.
CN⁻(aq) + H⁺(aq) ⇒ HCN(aq)
