Answer:
(K) = [H2] [Cl2] / [HCl]²
Explanation:
The equation of the reaction is given as;
2 HCl (g) ⇔ H2 (g) + Cl2 (g)
The Equilibrium constant is the ratio of the concentration of the products and reactants raised to the power of their coefficients
Products = H2 and Cl2
Reactants = HCl
Equilibrium constant (K) = [H2] [Cl2] / [HCl]²
Explanation:
The enthalpy of a reaction for a chemical change can be determined by
Using the formula ∆H = m x s x ∆T to solve.
∆H is the change in the enthalpy of the reaction.
where, m, the mass of our reactants,
s, the specific heat of our product,
and ∆T, the temperature change during the reaction,
Thus, we are ready to calculate the enthalpy of reaction.
Simply we can put in values into the formula ∆H = m x s x ∆T and multiply to solve.
Answer:
0.20 mol's
Explanation:
1.675 L = 1.675 dm^3
moles = V/(conc):
moles = 1.675/(8.5)
moles = 0.1970... --> 0.20
Answer: Water is made out of 3 atoms, 2 hydrogens and 1 oxygen.
Therefor, there answer will be A.
Hope this helps! :D
