What is the gram formula mass of Ca3(PO4)2

Answers

Answer 1

Answer: Mass Molar of $Ca_(3) (PO_4)_2$
Ca = 3*40 = 120 amu
P = 2*31= 62 amu
O = (16*4)*2 = 64*2 = 128 amu
--------------------------------------
Mass Molar of $Ca_(3) (PO_4)_2$ = 120 + 62 + 128 = 310 g/mol

Therefore: What is the gram formula mass of Ca3(PO4)2 ?
Answer: 310 grams

At equilibrium, a sample of gas from the system is collected into a 4.00 L flask at 600 K. The flask is found to contain 3.86 g of PCl₅, 12.7 g of PCl₃, and 13.3 g of Cl₂. What are the values of Kc and Kp for this reaction?

Answers

Answer:

Explanation:

PCl₅ ⇄ PCl₃ + Cl₂

1 mole 1 mole 1 mole

molecular weight of PCl₅ = 208.5

molecular weight of PCl₃ = 137.5

molecular weight of Cl₂ = 71

moles of PCl₅ = .0185

moles of PCl₃ = .0924

moles of Cl₂ = .1873

Total moles = .2982 moles

mole fraction of PCl₅ = .062

mole fraction of PCl₃ = .31

mole fraction of Cl₂ = .628

If total pressure be P

partial pressure of PCl₅ = .062 P

partial pressure of PCl₃ = .31 P

partial pressure of Cl₂ = .628 P

Kp = .31 P x .628 P / .062 P

= 3.14 P

To calculate Total pressure P

PV = nRT

P x 4 x 10⁻³ = .2982 x 8.31 x 600

P = 371.7 x 10³

= 3.717 x 10⁵ Pa

Kp = 3.14 P = 3.14 x 3.717 x 10⁵ Pa

= 11.67 x 10⁵ Pa

Kp = Kc x $( RT )^(\triangle n)$

$\triangle n$ = 1

11.67 x 10⁵ = Kc x $( 8.31* 600 )^(1)$

Kc = 234

Why does ionization energy decrease moving down a group in the periodic table?

Answers

Answer:

Electron shielding

Explanation:

Ionization energy decreases moving down a group in the periodic table because of a phenomen known as Electron shielding, in which valence electrons do not interact with the positively charged nucleus as strongly as inner electrons do, because these inner electrons shield the valence electrons. This means it's easier for these valence electrons to leave the atom the more inner electrons are between them and the nucleus, this translates into a decreased ionization energy value.

Look closely at the valence electrons in all eight columns of your table from part C. Which element's location does notmatch the pattern shown in the table?
o helium (He)
o hydrogen (H)
sodium (Na)
O argon (Ar)

Answers

Answer: helium(He)

Explanation: Helium has only 2 electrons in the outermost energy level, but all of the other elements in its column have eight.
