Answer:
It goes through our digestive system then though our bladder.
From the balanced equation:
<span>1mol C3H8 requires 5mol O2 for combustion </span>
<span>Molar mass C3H8 = 44g/mol </span>
<span>8.8g C3H8 = 8.8/44 = 0.2mol C3H8 </span>
<span>This will require 5*0.2 = 1.0mol O2 </span>
<span>Molar mass O2 = 32g/mol </span>
<span>Therefore 32g of O2 required.

Explanation:
The temperature of the stratosphere (which contains Earth's ozone layer) actually increases in temperature as you move higher, so the statement is false. This phenomenon is caused by the absorption of solar radiation by ozone molecules concentrated in the upper stratosphere.
Answer:
Unit cells which are present per cubic centimeter of Ag =
Volume =
Edge length =
Explanation:
(a)
Given that:-
The density of the solid Ag = 10.5 g/cm³
Molar mass of silver = 107.8682 g/mol
So, Moles present per cm³ of Ag = =0.0973 mol/cm³
Also, 1 mole = atoms.
So,
Atoms present per cm³ of Ag =
Thus, answer =
In FCC, the number of atoms in the unit cell = 4 unit cells
So,
Unit cells which are present per cubic centimeter of Ag =
<u>Unit cells which are present per cubic centimeter of Ag = </u>
(b)
The reciprocal of the unit cell/cm³ is the volume of the unit cell.
So,
<u>Volume = </u>
(c)
Also, Volume =
Thus, edge length = =
<u>Edge length = </u>
Answer:
(a) (b)
