Answer:
Atomic Oribal
Explanation:
There are four basic types of electron orbitals – s, p, d, and f. (Visual representations can be found in the tutorial above.) The s subshell is a spherical orbital which can contain up to two electrons. Each energy level has one s subshell.
Answer:
50g iron comprises 5.376 × 1023 atoms.
Explanation:
Calculate the pOH first :
pOH =14-8.57=5.43
(OH)=10^-5.47
(OH)=3.72 x 10^-6 mol/L
Answer:
163.2 g of Li₃PO₄ are made in the reaction
Explanation:
In first place we determine the reaction, to see stoichiometry.
The reactants are Li and Pb₃(PO₄)₂; the products are Li₃PO₄ and Pb
Equation: 6Li + Pb₃(PO₄)₂ → 2Li₃PO₄ + 3Pb
6 moles of Li can produce 2 moles of lithium phosphate
Therefore, 4.22 moles of Li will produce (4.22 . 2) / 6 = 1.41 moles of Li₃PO₄
Let's convert the amount to mass, to find the answer:
1.41 mol . 115.79 g / 1mol = 163.2 g
