Answer:A pseudo-noble gas configuration is: 1s2 2s2 2p6 3s2 3p6 3d10. Cu^+ has this electron configuration. The answer is C)
Explanation:
Answer:
Gases as might be expected, increase in solubility with an increase in pressure. Henry's Law states that: The solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution. ... When the bottle is opened, the pressure above the solution decreases.
Answer:
The number of grams is 434.5 g.
Explanation:
Answer:
Noble gases are odorless, colorless, nonflammable, and monotonic gases that have low chemical reactivity. The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons.
Explanation:
Al2O3
16=molar mass of one oxygen atom
Number of moles: mass/molar mass
Mol of O3: 19÷(16*3) = 0.40 g/mol
mole ratio
0.40: 3 (oxygen)
0.27: 2 (aluminum)
Mass = molar mass*mole
0.27*(27*3)= 21.87g
