How many grams of P4O10 are produced if you burn 50.0 g of phosphorus with sufficient oxygen?

Chemistry
1 answer:
Nata [24]3 years ago
7 0

Answer:

114.4 grams of P₄O₁₀

Explanation:

P₄   +   5O₂   →   P₄O₁₀

50 grams of P₄ are (50 g / 123.88 g/m) = 0.403 moles

Ratio is 1:1 so 0.403 moles of phosphorus can produce the same amount of P₄O₁₀.

Molar mass P₄O₁₀ = 283.88 g/m

0.403 moles . 283.88 g/m = 114.4 g

If the half-life of a radionulide is 1 month, what percent remains after 4 months?
Aliun [14]

Answer:

6.25% of the original amount

Explanation:

half-life means that half is gone for every certain period of time. Because the half life is 1 month, only half of the 'radionulide' is left every month.

after 1 month= 50%

after 2 months= 25%

after 3 months= 12.5%

after 4 months= 6.25%

How does a meteorologist use an understanding of what causes weather to predict a storm?
Svetllana [295]
Meteorologists also use satellites to observe cloud patterns around the world, and radar is used to measure precipitation. All of this data is then plugged into super computers, which use numerical forecast equations to create forecast models of the atmosphere.

A hypothetical metal crystallizes with the face-centered cubic unit cell. The radius of the metal atom is 234 picometers and its
AleksAgata [21]

Answer:

\delta=101.13 g/cm^3

Explanation:

As can be seen in the Figure in a face-centered cubic unit cell you have:

  • Six halves of atoms
  • Eight 1/8 of atom (1 in each corner)

In total:

n_{atom}=6*0.5+8*\frac{1}{8}=4 atoms

Now, each side of the cell is 234 picometers (2.34e-8 cm) long

V_{cell}=L^3=(2.34e^{-8} cm)^3

V_{cell}=1.28*10^{-23}cm^3

Atoms per cm3:

n=\frac{4 atoms}{1.28*10^{-23}cm^3}

n=3.12*10^{23} atoms/cm^3

Expressing in mass:

\delta=3.12*10^{23} atoms/cm^3* \frac{1 mol}{6.022*10^{23}}*195.08 g/mol

\delta=101.13 g/cm^3
