Answer:
T₁ = 135.41 K
Explanation:
Given data:
Initial pressure = 1.12 atm
Finial temperature = 36.5 °C (36.5 +273 = 309.5 K)
Initial temperature = ?
Final pressure = 2.56 atm
Formula:
P₁/T₁ = P₂/T₂
P₁ = Initial pressure
T₁ = Initial temperature
P₂ = Final pressure
T₂ = Final temperature
Solution:
P₁/T₁ = P₂/T₂
T₁ = P₁T₂ /P₂
T₁ = 1.12 atm × 309.5 K / 2.56 atm
T₁ = 346.64 atm . K / 2.56 atm
T₁ = 135.41 K
The main difference between concentration and density is that concentration refers to how much of a substance is present in a mixture, whereas density refers to the mass of a substance per unit volume.
Answer:Well-known examples are sodium hydroxide (NaOH) with OH- as the polyatomic anion, calcium carbonate (CaCO3), and ammonium nitrate (NH4NO3), which contains two polyatomic ions: NH+ and NO3-. ... The properties of compounds containing polyatomic ions are very similar to those of binary ionic compounds.
