Answer:
sodium
Explanation:
sodium is the second most reactive. Magnesium being the least reactive
Answer:
1 and a half cups
Explanation:
12 ounces is equivalent to 1.5 cups
Answer:
So the molar mass of C4,H10 is
58.12g mole -1
<span>he ratio of the RMS velocities is 0.837
Now the RMS velocity is inversely proportional to the square root of the Mol Wt
So we have V1/V(N2) = sq rt (28/M1)
So [V1/V(N2)]^2 = 0.837^2 = 0.70 = 28/M1 from which M1 = 28/0.7 = 39.97 (Ar)</span>
