substance
Explanation:
A pure substance is a form of matter that has a constant composition (meaning it's the same everywhere) and properties that are constant throughout the sample (meaning there is only one set of properties such as melting point, color, boiling point, etc
Answer:
I think you meant HNO3 + CuCO3 ---> H2O + CO2 + Cu(NO3)2. If so, then the balanced equation would be : 2 HNO3 + CuCO3 ---> H2O + CO2 + Cu(NO3)2
Answer:
5.82 L
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 2.25 L
V₂ = ?
P₁ = 2.7 atm
T₁ = 12 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (12 + 273.15) K = 285.15 K
At STP, Pressure = 1 atm and Temperature = 273.15 K
So,
P₂ = 1 atm
T₂ = 273.15 K
Using above equation as:
Solving for V₂ , we get:
<u>V₂ = 5.82 L</u>
