Choose the thermochemical equation that best illustrates ΔH°f (enthalpy of formations) for Li2SO4. A) 2 Li+(aq) + SO42-(aq) → Li

2SO4(aq) B) 2 Li(s) + 1/8 S8(s, rhombic) + 2 O2(g) → Li2SO4(s) C) Li2SO4(aq) → 2 Li+(aq) + SO4 2-(aq) D) 8 Li2SO4(s) → 16 Li(s) + S8(s, rhombic) + 16 O2(g) E) 16 Li(s) + S8(s, rhombic) + 16 O2(g) → 8 Li2SO4(s)

How many electrons can each individual orbital hold?
Hatshy [7]

Answer:

Orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron, and all electrons in singly occupied orbitals must have the same spin state. Noble-gas configuration refers to an outer main energy level occupied, in most cases, by eight electrons.

Explanation:

I hope this helps you.

Express 0.032 Ms in scientific notation using base units
bixtya [17]

0.032 Ms = 3.2 × 10^4 s

<em>Step 1</em>. Convert the number to scientific notation.

0.032 = 3.2 × 10^(-2)

<em>Step 2</em>. Convert the measurement to base units.

3.2 × 10^(-2) Ms × (10^6 s/1 Ms) = 3.2 × 10^4 s

Now if your lab partner determined that there were 1.552 x 1022 atoms of H in an unknown sample of C2H4Cl2, how many milligrams
STALIN [3.7K]
To determine the mass of the sample in milligrams in this problem, we use the avogadro's number to convert from atoms to moles, relate the moles of element in the sample to the mole present and the molar mass of the sample. We do as follows:

1.552 x 10^22 atoms H ( 1 mol H / 6.022x10^23 atoms H ) ( 1 mol C2H4Cl2 / 4 mol H ) ( 98.96 g C2H4Cl2 / 1 mol C2H4Cl2 ) = 0.625 g C2H4Cl2 = 625 mg <span>C2H4Cl2</span>
