Answer:
If the temperature of gas is decreased the pressure will also goes to decrease.
Explanation:
The pressure and temperature have direct relation. If the temperature of gas will increase the pressure of gas will also goes to increase.
According to the Gay-Lussas's Law,
The pressure of given amount of gas is directly proportional to the absolute temperature when volume is kept constant.
Mathematical relationship:
P ∝ T
P = kT
P/T = k
and
P₁/T₁ = P₂/T₂

Answer:
<h2>5080 mL</h2>
Explanation:
The volume of the gas at standard pressure can be found by using the formula for Boyle's law which is
Since we are finding the new volume
From the question we have
We have the final answer as
<h3>5080 mL</h3>
Hope this helps you
Answer:
Due to weak oxidizing agent.
Explanation:
In my opinion the results would be affected if using K2Cr2O7/H2SO4 as the oxidizing agent instead of KMnO4 because K2Cr2O7/H2SO4 is weak oxidizing agent as compared to KMnO4. An oxidizing agent is a substance that has the ability to oxidize other substances means that accept their electrons so that's why the results of strong oxidizing agent is different than weak oxidizing agent.
Answer:
5.42 mol
Explanation:
To find moles, divide the given mass by the compounds molar mass. To find the molar mass of the compound, add of the masses of each individual component:
Molar mass of NaNCO3 = Na + N + C + (O x 3)
Molar mass of NaNCO3 = 23 + 14 + 12 + (16 x 3)
Molar mass of NaNCO3 = 97 g/mol
Moles = mass / molar mass
Moles = 526 g / 97 g/mol
Moles = 5.42 mol
