Answer:
it would be the ideal gas law also known as Avagadro's law
Explanation:
Answer:
1. wa. Molecular form.
2. wa. Molecular form.
3. sa. Ionic form.
Explanation:
1. hydrocyanic acid
HCN is a weak acid. That means that in the following equilibrium, the molecular form (HCN(aq)) is favored, and that's how it should be written in solution.
HCN(aq) ⇄ H⁺(aq) + CN⁻(aq)
2. hypochlorous acid
HClO is a weak acid. That means that in the following equilibrium, the molecular form (HClO(aq)) is favored, and that's how it should be written in solution.
HClO(aq) ⇄ H⁺(aq) + ClO⁻(aq)
3. hydrochloric acid
HCl is a strong acid. That means that it completely dissociates and it should be written in the ionic form (H⁺(aq) + Cl⁻(aq)) when it is in solution.
HCl(aq) → H⁺(aq) + Cl⁻(aq)
Answer: E. It decreases the value of Eact.
Explanation:
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and more molecules convert to products.
The catalyst itself does not take part in the chemical reaction and is regenerated as such at the end.
Answer:
#atoms C-12 = 3.01 x 10²³
Explanation:
Convert grams to moles and multiply by Avogadro's Number.
6 g C-12 = (6g/12g·mol⁻¹) = 0.50 mol C-12
No. C-12 atoms in 0.50 mol C-12 = 0.50 mol C-12 x 6.02E23 atoms/mole = 3.01E23
Answer:
Explanation:
The expression for the calculation of the enthalpy change of a process is shown below as:-
Where,
is the enthalpy change
m is the mass
C is the specific heat capacity
is the temperature change
Thus, given that:-
Mass of object = 36.2 g
Specific heat = 12.5 J/g°C
So,
