Answer:
V₂ = 1866.32 mL
Explanation:
Given data:
Initial temperature = 27.8°C (27 + 273.15 K = 300.15 k)
Initial volume = 1500 mL
Final volume = ?
Final temperature = 100.0°C (100.0 + 273.15 K = 373.15 K)
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
1500 mL / 300.15 k = V₂ / 373.15 K
V₂ = 1500 mL× 373.15 K/ 300.15 k
V₂ = 560175 mL. K /300.15 k
V₂ = 1866.32 mL
Answer;
-H2O, water
Explanation;
-Hydrocarbons undergoes combustion to form water and carbon dioxide. Propane (C3H8) is a hydrocarbon that belongs to the homologous series alkanes. Thus, propane will undergo combustion to form 3 molecules of carbon dioxide and 4 molecules of water.
Thus the complete equation will be;
-C₃H₈ + 5O₂ = 3CO₂ + 4H₂O
Answer:
HCl is reduced and is the oxidizing agent
Explanation:
Looking at the reaction shown in the question
Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
HCl is reduced to H2. The oxidation number of hydrogen decreased from +1 to zero. While magnesium was oxidized. Its oxidation number increased from zero to +2.
Hence we can rightly say that HCl was the oxidizing agent since the oxidizing agent is reduced in a reaction and the reducing agent is oxidized in a reaction.
