Answer:
Δ
= -461198.3 J
Explanation:
Gibbs free energy is defined as the energy associated with a given chemical reaction which can be used to do work. Firstly, we need to figure out the chemical equation for the given problem. For the given problem, the chemical equation is:
⇒
⇒
The addition of the two 
gives the 
of the equation, i.e. -1.18-1.21 = -2.39 V.
Then, using the equation for Δ, we have:
Δ = n*F* = 2*96485*-2.39 = -461198.3 J
Answer is: standard metal cations are sodium cation (Na⁺), potassium cation (K⁺), magnesium cation (Mg²⁺) and calcium cation (Ca²⁺).
Soap<span> is a </span>salt<span> of a </span>fatty acid. When soap have sodium and potassim cations, that is toilet soap and when soap have magnesium and calcium cations, that soap is called <span>metallic soap.</span>
Answer:
d) 0.1202 M
Explanation:
Let's consider the neutralization reaction between NaOH and a generic monoprotic acid.
NaOH + HA → NaA + H₂O
The used volume of NaOH is 41.63 mL - 19.63 mL = 22.00 mL. The moles of NaOH are:
22.00 × 10⁻³ L × 0.1093 mol/L = 2.405 × 10⁻³ mol
The molar ratio of NaOH to HA is 1:1. The moles of HA that reacted are 2.405 × 10⁻³ moles.
The molar concentration of HA is:
2.405 × 10⁻³ mol / 20.00 × 10⁻³ L = 0.1202 M
Answer:
If you were speaking of the term mole as a skin condition then a teacher might compare it to a beauty spot. In the position your were speaking of it as an animal they might compare it to mouse a rat or a hamster. In the case you were speaking of a mole as a secret agent then a teacher might compare them to a double agent.
