2 mole Na needs 1 mole Cl2
4 mole Na = 2 mole Cl2
I was flung towards the atmosphere. Slowly but surely, I made my way inside. On my way there, I began to heat up. I began to vibrate rapidly, and I noted it happened as I entered the atmosphere. I think it was because we sped up so much, but I can't say for sure because I'm an air particle... However, I do know that I am now a heated air particle due to friction and movement from entering the atmosphere. I think I'll cool down on my descent, I don't know that I can get much hotter than this.
Answer:
The correct answer is - 0.570 grams
Explanation:
The balanced chemical reaction is given by
Cu(NO3)2(aq) + 2NaOH(aq) --------> Cu(OH)2(s) + 2NaNO3(aq)
1.0 mole 2.0 mole 1.0 mole 2.0 mole
number of mol of Cu(OH)2,
n = Molarity * Volume
= 
millimoles
As clear in the equation, 1 mole of Cu(NO3)2 gives 1 mole of Cu(OH)2
, So, 5.845 millimoles of Cu(NO3)2 will produce 5.845 millimoles of Cu(OH)2
Mass of Cu(OH)2 = number of mol * molar mass
= 
= 0.570 grams
Thus, the correct answer is - 0.570 grams
The answer for this question is:
B. Scientific notation is used to keep track of very small and very large numbers during mathematical calculations.
