Answer:
Pressure=3.91atm
Explanation:
As given in the question that gas is ideal so
we can use Ideal gas equation
volume of gas is not given directly but volume of container is given and we know gas takes the volume in which they are kept.
therefore mole remains contant
P1=2.5 atm
V1=2L
T1=320K
P1=?
V1=1L
T1=250K
..............(1)
................(2)
eqn2/eqn1
Pressure=3.91atm
The equation is as below,
<span>5 Ag</span>⁺ (aq) + Mn²⁺ <span>(aq) + 4H</span>₂<span>O (l) → 5Ag (s) + MnO4</span>⁻<span>(aq) + 8H</span>⁺ <span>(aq)
Reduction:
According to eq. Silver is reduced as,
</span>
5 Ag⁺ + 5 e⁻ → 5 Ag
One electron is gained per Ag ion, so 5 Ag ions will gain 5 electrons.
Oxidation:
According to eq. Manganese is Oxidized as,
Mn²⁺ → MnO4⁻
Oxidation number of Mn in MnO₄⁻ is +7, so Mn²⁺ is loosing 5 electrons, Hence,
Mn²⁺ → MnO4⁻ + 5 e⁻
Results:
Hence, 5 moles of electrons are exchanged between oxidizing and reducing agents.
Answer:
this
Explanation:
What is the unit rate of the better deal? (Number answers only.)
LaTeX: \frac{160\:miles}{5\:gallons}\:or\:\frac{315\:miles}{9\:gallons}160 m i l e s 5 g a l l o n s o r 315 m i l e s 9 g a l l o n s
The better deal has a unit rate of [m] miles per gallon.
