Answer : The volume of 1 mole of and
gases are the same.
Solution: Given,
Moles of = 1 mole
Moles of = 1 mole
Moles of = 2 mole
Formula used for ideal gas is :
P V = n R T
According to the question, the gases are at standard temperature and pressure. So, the volume of gases only depends on the number of moles. This means that the higher the number of moles, higher will be the volume of gas.
The moles of are more than the moles of
and
. So, the volume of
will be more.
And the moles of and
are equal. Therefore, their volumes are also equal.
Therefore, the best option is the volume of 1 mole of and
gases are the same.
Answer:
concentration of = 0.0124 = 12.4 ×10⁻³ M
concentration of = 0.0248 = 2.48 ×10⁻² M
concentration of = 0.4442 M
Explanation:
Equation for the reaction:
⇄
+
Concentration of =
= 0.469
For our ICE Table; we have:
⇄
+
Initial 0.469 0 0
Change - 2x +2x +x
Equilibrium (0.469-2x) 2x x
K =
K =
Since the value pf K is very small, only little small of reactant goes into product; so (0.469-2x)² = (0.469)²
x = 0.0124
∴ at equilibrium; concentration of = 0.0124 = 12.4 ×10⁻³ M
concentration of = 2x = 2 ( 0.0124)
= 0.0248
= 2.48 ×10⁻² M
concentration of = 0.469-2x
= 0.469-2(0.0124)
= 0.469 - 0.0248
= 0.4442 M
Oxidation reaction is a type of reaction wherein there is a loss of electrons. An oxidation reaction may also be a reducing agent. Example is the reaction Zn + 2H+ = Zn2+ + H2. When you separate them by their half cell reaction, you have 2H+ 1e- = H2. H here is the reducing agent and has lost 1 electron in the process.
b. Ionic solids have higher melting points than molecular solids.
c. Molecular solids have higher melting points than all other types of solids.
d. It is impossible for solids to melt; therefore solids do not have melting points.
B. Ionic solids have higher melting points than molecular solids.
(2) covalent, because valence electrons are transferred
(3) ionic, because valence electrons are shared
(4) ionic, because valence electrons are transferred
(2) lose electrons and have an increase in oxidation number
(3) gain electrons and have a decrease in oxidation number
(4) gain electrons and have an increase in oxidation number
redox reactions deal with the transfer of electrons from one species to another species
redox reactions are made of reduction reactions and oxidation reactions
reduction reactions are when electrons take in electrons and results in a decrease in the oxidation number
oxidation reactions are when electrons give out electrons resulting in an increase in the oxidation number
therefore correct answer for reduction reactions are
(3) gain electrons and have a decrease in oxidation number
