A 3.1 L sample of hydrogen <u>d. contains the same number of molecules</u>
as 3.1 L of carbon dioxide at the same temperature and pressure.
This is the fundamental principle of <em>Avogadro’s hypothesis</em>: equal volume of gases at the same temperature and pressure contain the same number of molecules.
The sample of carbon dioxide has a <em>greater mass</em>, a <em>greater number of atoms</em>, and a <em>greater density</em>, than the sample of hydrogen.
Upon a constant pressure (P), volume (V) of a gas will vary in direct proportion to changes in temperature (T). So V1/T1 = V2/T2
V2 = V1T2/T1 = (500)(300)/150
V2 = 150000/150 = 1000 mL
Answer:
Explanation:
A Lewis acid is defined as a chemical species that contains an empty orbital which accepts an electron pair from a Lewis base to.
A Lewis base is defined as any species that has a filled orbital containing an electron pair which is not involved in bonding but forms a dative bond with a Lewis acid.
A. Fe3+ + 2H2O --> FeOH2+ + H30+
Fe3+ - Lewis acid
H2O - Lewis base
B. H2O + H- --> H2 + OH-
H- - Lewis acid
H2O - Lewis base
C. 4CO + Ni --> Ni(CO)4
CO - Lewis base
Ni - Lewis acid
Answer:
<h2>The answer is 8 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 16 g
volume = 2 cm³
The density is
We have the final answer as
<h3>8 g/cm³</h3>
Hope this helps you
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic
For P and Cl,
E.N of Chlorine = 3.16
E.N of Phosphorous = 2.19
________
E.N Difference 0.97 (Polar Covalent)
For K and Br,
E.N of Bromine = 2.96
E.N of Potassium = 0.82
________
E.N Difference 2.14 (Ionic)
For C and C,
E.N of Carbon = 2.55
E.N of Carbon = 2.55
________
E.N Difference 0.00 (Non-Polar Covalent)
