Answer: The statement which could possibly not be true is C -" Liquid X can exist as a stable phase at 25°C, 1atm."
Explanation:
Triple point is the point where a substance co-exist as solid liquid and gas. At any point other than the triple point, the substance exist as a single phase substance.
As shown in the diagram, Liquid cannot exist as a stable phase at 1atm( below the the triple point pressure of 2atm) as the liquid can only exist beyond the pressure of triple point.
The Best Answer: 1 - (.47+.23) = 0.30
If Ne has a mole fraction of 0.47 (or 47/100) and Ar is 0.23, then H2(or He) has a mole fraction of 0.30
This means the gas mixture is 30/100 H2(or He).
7.85 x 0.30 = 2.355 atm
Answer:
If pOH is 3.05, pH is 10.95 or
[H+]=1.122⋅10−11 mol/L
Explanation:
pH=−log(H+)Now, what is H+
if your pH is 10.95 (since pH+pOH=14, your pH=10.95).
(H+)=10 −10.95
(H+)=1.122⋅10 −11
This is your hydrogen ion concentration: [H+]=0.00000000001122 mol/L
Answer: As the airplane goes higher, the mechanical energy is changed into gravitational potential energy. While flying, some energy is lost through drag to thermal (heat) energy and sound energy. Some is also lost as the plane makes the air around it move. ... As speed and height decrease, kinetic and potential energy decrease.

Answer:
In this chemical reaction, KOH is a reactant.
Explanation:
Reactants are those substances which are present on the left side of the reaction. These reactants react with each other to form products. In this chemical reaction, Potassium hydroxide (KOH) reacts with hydrogen bromide (HBr) producing potassium bromide and water molecules. These substances are formed by exchanging their atoms and make chemical bonds with each other.
