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.
Using the relationship M1V1 = M2V2 where M1 and M2 are the molar concentrations (mol/L or mmol/ml) and V1 and V2 are the volumes of the solutions, we can arrive at the following answer for the given problem:
<span>15.0M (L of stock solution) = 2.35M (0.25L) *all volumes were converted to liters.
L of stock solution = (2.35*0.25)/15.0
Therefore, 0.0392L or 39.17 ml of stock solution is needed. </span>
Answer:
Lava is hot liquid rock. When lava flows over solid ground, the solid ground beneath it increases in temperature. What happens to the molecules in the solid ground when the temperature is increasing? The energy of the molecules in the ground decreases.
Answer:
The Answer is 88%
Explanation:
The balanced ionic equation of the reaction



Looking at the above reactions
The original number of moles of
= 3 × number of moles of 
= 3 × volume × concentration of
Note: The formula for number of moles is volume × concentration
mol
The number of moles of
left after its reaction with ascorbic acid
=
x moles of 
=
x volume x concentration of 

Note: The division by 1000 is to convert mill liter to liter
Moles of ascorbic acid = moles of
reacted



Hence
Mass of ascorbic acid = moles of ascorbic acid × molar mass of ascorbic acid


Weight% of ascorbic acid = mass of ascorbic acid/mass of sample x 100%
= 70.55/80 × 100%
= 88.1%
It's inertia. Inertia is the force that resists change in motion, like the planets and gravity. Inertia is effected by gravity
