Explanation:
Apply Boyle's Law :-
P1V1 = P2V2
- Where P1 is 25 atm
- V1 is 3L
- P2 is 75 atm
- V2 is what we need to find out.
25 × 3 = 75 × V2
<u>So, the answer is d) Part, 1L .</u>
Hope it helps :)
Answer:
Mass = 2.355 g
Explanation:
Given data:
Mass of K₂O needed = ?
Mass of KNO₃ produced = 5.00 g
Solution:
Chemical equation:
K₂O + Ca(NO₃)₂ → CaO + 2KNO₃
Number of moles of KNO₃:
Number of moles = mass/molar mass
Number of moles = 5.00 g/ 101.1 g/mol
Number of moles = 0.05 mol
now we will compare the moles of KNO₃ and K₂O.
KNO₃ : K₂O
2 : 1
0.05 : 1/2×0.05 = 0.025 mol
Mass of potassium oxide needed in gram:
Mass = number of moles × molar mass
Mass = 0.025 mol × 94.2 g/mol
Mass = 2.355 g
Answer:
Balanced chemical equation:
2AgNO₃ + Zn → ZnNO₃ + 2Ag
Type of reaction:
It is the single replacement reaction.
Explanation:
Consider the reaction between zinc and silver nitrate. In this chemical reaction the zinc is substituted in place of silver in silver nitrate compound.
Chemical equation:
AgNO₃ + Zn → ZnNO₃ + Ag
Balanced chemical equation:
2AgNO₃ + Zn → ZnNO₃ + 2Ag
The starting material consist of compound ( AgNO₃) and pure element (Zn).
After reaction a new compound ( ZnNO₃) and pure element (Ag) is generated.
Type of reaction:
It is the single replacement reaction.
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Explanation:
Distillation is defined as a process in which two liquids with a temperature difference less than 25^{o}C are boiled together. As a result, liquid with low boiling point vaporizes and collected in a separate container.
Hence, separation of both the liquids take place.
When we carry out slow distillation then both vaporization and condensation takes place simultaneously more effectively. Hence, an equilibrium is maintained.
And, when we do fast distillation then vapors do not condense as quickly as desired. Hence, liquids will not separate out easily.
