This is an ideal gas problem. The gas inside the balloon is considered ideal. Ideal gas equation is a function pressure, temperature, amount and volume. Note: amount is constant since the balloon ins closed. Pressure is maintained constant since the walls are flexible. Ideal gas equation is: PV=nRT. Put all constant in one side and variables in one.
P/nR=T/V. To find the answer to the question equate the constants of both situation
T1/V1=T2/V2
(25+273.15)/3=(x+273.15)/2
x=-74.38 degC
Explanation:
When an object is at rest, the body is said to possess potential energy. In another case, when the object is in motion, then it is said to possess kinetic energy. Potential energy tends to affect the object within the environment if and only when it gets transformed to other kinds of energy.
Answer:
20.8 Lof NH₃ are needed for the reaction
Explanation:
This is the reaction:
4 NH₃ + 6 NO → 5N₂ + 6H₂O
and the info. we need
Ammonia density = 0,00073 g/mL
Let's determine the moles of NO at STP by the Ideal Gases Law equation
P . V = n . R .T
1atm . 30L = n . 0.082 . 273K
(1atm . 30L) / (0.082 . 273K) = n → 1.34 moles of NO
Let's find out the amount of ammonia that should react
6 mol of NO react with 4 mol of ammonia
1.34 mol of NO will react with (1.34 .4)/6 = 0.893 moles of ammonia
Molar mass NH₃ = 17 g/m
0.893 mol . 17 g/m = 15.19 g of ammonia
Ammonia density = 0,00073 g/mL = NH₃ mass / NH₃ volume
0,00073 g/mL = 15.19 g / NH₃ volume
NH₃ volume = 15.19 g / 0,00073 g/mL → 20805.5 mL ⇒ 20.8 L
When hydrogen is attached to a more electronegative element, the more electronegative atom becomes partially negative.
Volume of Oxygen O2 would be 33 L.
Solution : Given information - Mole (n) = 6.9 mol
Pressure (P) = 4.0 atm
Temperature (T) = 233 K
Universal gas constant (R) = 0.0821 L.atm/mol.K
Volume(V) is unknown , which we need to find.
Volume can be calculated by using the Ideal gas equation which is :
PV = nRT (Ideal gas equation)
On rearranging the above formula we will get :
Where , P = pressure , V = volume , n = mole , R = universal gas constant , T = temperature.
We will plugin the values of P , n , R and T in the ideal gas equation and then calculate Volume (V)
V = 32.998 L or 33 L
