Answer:
4.27 moles of NaCl
Explanation:
Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol
Number of moles of NaCl(table salt) = 250 grams /58.5 g/mol
= 4.27 moles of NaCl
Answer:
B) Δ[C]/Δt = 3,60x10⁻² M⁻¹s⁻¹ [A] [B]
Explanation:
For the reaction A + B → C
The formula for rate of reaction is:
Δ[C]/Δt = k [A] [B]
As you have [A], [B] and Δ[C]/Δt information you can multiply [A] times [B] and take this value as X and Δ[C]/Δt as Y. The slope of this lineal regression will be k.
Thus, you must obtain:
y = 3,60x10⁻² X
Thus, rate of reaction is:
B) Δ[C]/Δt = 3,60x10⁻² M⁻¹s⁻¹ [A] [B]
I hope it helps!
Sodium chloride if it’s not im sorry :)
