Mg (s) ---> Mg²⁺ (aq) + 2e
Co²⁺ (aq) + 2e ---> Co(s)
Cu (s) ---> Cu²⁺ (aq) + 2e
Au²⁺ (aq) + 2e ---> Au(s)
Than you for posting your question here. I hope the answer helps.
The answer as to be grams (g) since you it is aske for mass. What you have for units is 1/g.
<span>Very close. The factor is 5. </span>
<span>answer is 5 * 65 g of water.</span>
The answer to the question is B......
Answer is B, because CaSO3 only has one S
4.1 h = 14760 s
<span>t 1/2 = ln 2 / k </span>
<span>k = rate reaction = 4.97 x 10^-5 </span>
<span>ln 0.045 / 0.36 = - 4.97 x 10^-5 t </span>
<span>2.08 = 4.97 x 10^-5 t </span>
<span>t = 41839.9 s = 11 h 37 min 19 s</span>
