1mole produce 18g/x will produce 32g then the answer is 1.78moles
Explanation:
While atomic radii DECREASE across a Period, a row of the Period Table, from left to right as we face the Table, atomic radii INCREASE down a Group, a column of the Periodic Table, due to the shielding of the valence electrons by the closed valence shell(s) that intervenes between the nucleus and the valence, outermost electrons.
Answer:
sodium/potassium/rubidium/caesium/francium
Explanation:
all are group I elements, so they all have similar properties
Answer:
0.0111mol/L
Explanation:
M = n/V
We don't know n, but we know that n =mass/Molar mass, so:
n = 8.77g/166.0028 g/mol
n = 0.0528304342mol
M = n/V
M = 0.0528304342mol/ 4.75L
M = 0.111221967mol/L
Round to three sig figs if necessary: 0.0111mol/L
Explanation:
The right answer is Look .........
