Answer:
Moles = 0.5 mol
Solution:
Moles is related to mass as follow,
Moles = Mass / M.mass ----- (1)
Where;
Mass = 50 g
M.mass = Ca (40) + C (12) + O₃ (16)₃ = 100 g/mol
Putting values in equation 1,
Moles = 50 g ÷ 100 g.mol⁻¹
Moles = 0.5 mol
The best answer is no bc the question ask "Would the two as yet undiscovered element A+1 and D+2" don't sound right

Answer:
the second sample has a broader range because it has more impurity by percentage
Explanation:
separation techniques
Answer:
Carbon has six electrons (2 core and 4 valence), and can form four bonds with neighboring atoms. Nitrogen has seven electrons (2 core and 5 valence)(1s2, 2s2, 2px1, 2py1, 2pz1). So if you are following the rules, you might well assume that nitrogen would be able to form five bonds (after all, it has five valence electrons.)
