The lower the specific heat the faster the temperaature will change.
You can learn it from the formula:
Q = m * Cs * ΔT
You can solve for ΔT
ΔT = Q / ( m * Cs)
Given the heat (Q) and m (100 g) are equal for the five samples:
ΔT = [Q / m] / Cs. = constat / Cs
So you see the inverse relation between the change of temperatura and the specific heat.
So, the order of change of temperature is given by the specific heat: the lower the specific heat the faster the change of temperature.
With that analysis you can calculate the order in which the cubes will reach the target temperature.
Q is unlike K value it describes the reaction that is not at equilibrium.
by considering this reaction:
aA+ bB⇄ cC
and our reaction is:
Br2 + Cl2 ⇄ 2 BrCl
According to Q low:
Q= concentration of products/concentration of reactants
but this equation in the gaseous or aqueous states only.
∴ Q = [BrCl]^2 / [Br2] [Cl2]
and we have [Br2] = 0.00366 m [Cl2]= 0.000672 m [BrCl] = 0.00415 m
by substitution:
= [0.00415]^2 / ( [0.00366] * [0.000672])
∴ Q = 7
Sodium Chloride because its still a liquid at the 773 temperature mark<span />
Answer:
lignands, the central atom/metal ion
Explanation:
Answer:
ΔG°rxn = -72.9 kJ
Explanation:
Let's consider the following reaction.
HCN(g) + 2 H₂(g) → CH₃NH₂(g)
We can calculate the standard Gibbs free energy of the reaction (ΔG°rxn) using the following expression:
ΔG°rxn = ΔH° - T.ΔS°
where,
ΔH° is the standard enthalpy of the reaction
T is the absolute temperature
ΔS° is the standard entropy of the reaction
ΔG°rxn = -158.0 KJ - 387 K × (-219.9 × 10⁻³ J/K)
ΔG°rxn = -72.9 kJ
