<h3><u>Answer</u>;</h3>
= 226 Liters of oxygen
<h3><u>Explanation</u>;</h3>
We use the equation;
LiClO4 (s) → 2O2 (g) + LiCl, to get the moles of oxygen;
Moles of LiClO4;
(500 g LiClO4) / (106.3916 g LiClO4/mol)
= 4.6996 moles
Moles of oxygen;
But, for every 1 mol LiClO4, two moles of O2 are produced;
= 9.3992 moles of Oxygen
V = nRT / P
= (9.3992 mol) x (8.3144621 L kPa/K mol) x (21 + 273) K / (101.5 kPa)
= 226 L of oxygen
Answer:
V = 4/3 * 3.1416 * (37x10-10)3
V = 2.12x10-25 cm3
d = m/V
d = 1.67x10-24 / 2.12x10-25 = 7.87 g/cm3
The difference in temperature, let's convert F to ºC:
ºC = -80-32/1.8 = -62.22 ºC
dT = -92.6 + 62.2 = -30.4 ºC
They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance
Answer:
The cube of gold will have the greatest mass.
Explanation:
All the cubes have the same size, so they have the same volume.
The property that varies among the cubes is density.
D = m/V Multiply both sides by V and transpose.
m = DV
Since V is a constant, m ∝ D.
That is, the cube with the greatest density will have the greatest mass.
The observed densities are
Iron = 7.9 g/cm³
Brass = 8.5 g/cm³
Lead = 11.4 g/cm³
Gold = 19.3 g/cm³
Gold has the greatest density, so the cube of gold has the greatest mass.
