It would be 3C + 4H2 -> C3H8
The chemical formula for this compound is CaCl2.
Answer:
V₂ = 0.74 L
Explanation:
Given data:
Initial volume of balloon = 0.75 L
Initial temperature of balloon = 27°C (27+273.15 K = 300.15 K)
Final volume of balloon = ?
Final temperature = 22°C (22+273.15 K = 295.15 k)
Solution:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 0.75 L × 295.15 k / 300.15 K
V₂ = 221.36 L.K / 300.15 K
V₂ = 0.74 L
The given problem is solved 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
Answer is b..............…
Answer:
Chemically combined and cannot be separated
Explanation:
1)A minimum of two atoms combine to form a molecule.
2)Atoms are combined via chemical reactions thus chemically combined. Sodium+Chlorine
e.g Na+Cl—>NaCl²
