The solubility of gas in water at 25 C and 1.0 atm pressure of oxygen is 0.061 g/ L. What would the pressure be if the solubility of oxygen water at 25 C is 0.075 g/L
Answer:
P2 = 1.2265 atm (Approx)
Explanation:
Given:
Water temperature = 25 degree Celsius
Pressure = 1 atm
So,
P1/P2 = C1/C2
1 / P2 = 0.061 / 0.075
P2 = 1.2265 atm (Approx)

Why does citric acid make water cold?
The reaction between citric acid and water is endothermic.
There are two types of reactions based on whether heat is evolved or absorbed by a reaction. Those two types are:
Endothermic reaction - in this reaction, heat is absorbed thereby making the reaction vessel to feel cold. Exothermic reaction- in this type of reaction, heat is evolved thereby making the reaction vessel to feel warm.The dissolution of citric acid in water is an endothermic reaction. The water feels cold because heat is absorbed from the surroundings as the reaction proceeds.

Changes in which two characteristics can indicate a physical change?
A. Shape
B. Reactivity
O C. State
D. Flammability
Changes in shape and state are the two characteristics which indicate a physical change.
What are physical changes?Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.
Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.
They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

Kinetic Theory: Tutorial
Activity
In this activity, open the Gas Properties simulation and follow the instructions provided with the questions below.
Part A
Using the controls along the right side of the simulation, under "Options," check the second box to select the temperature of the new particles
Then move the slider at the bottom to its lowest setting (50 K). Next, choose temperature as your constant parameter at the top. In the "Gas in
Chamber" box, add "light species" particles until about 200 are in the box. Finally, quickly add about 20 "heavy species" particles to the box.
Carefully observe how they spread across the chamber through time. What do you think causes the heavy particles to spread throughout the
chamber? What can you say about the direction of their movement?
Answer:
The heavy particles move across the chamber because of the diffusion property of gas particles. The particles move in straight lines and change directions only when they collide with other molecules or the walls of the chamber.

Which properties are most common in nonmetals
According to the electronic configuration, properties which are most common in non-metals are high ionization energies, high electronegativity and poor conductors of heat and electricity.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

A quantity of gas under a pressure of 302kpa has a volume of 600cm3. The pressure is increased to 604kPa, while the temperature is kept constant. What is the new volume?
Answer:
V₂ = 300 cm³
Explanation:
Given data:
Initial pressure = 302 KPa
Initial volume = 600 cm³
Final pressure = 604 KPa
Final volume = ?
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
302 KPa × 600 cm³ = 604 KPa× V₂
V₂ = 181200 KPa.cm³ / 604 KPa
V₂ = 300 cm³
