Answer:
The answer is C. The partial pressure of hydrogen will be unchanged.
Explanation:
⇒ 
Argon with electronic configuration
(that is atomic number 18) is an inert gas making it unreactive and it's addition to the reaction has no effect on the partial pressure of either the reactant or production or the state of the system.
The partial pressure of hydrogen will remain unchanged on the addition of Argon.
Answer: Skier 1 will have more potential energy because he is higher than skier 2
Explanation: Gravitational potential energy is the energy possessed by a body by virtue of its position or height.
P.E=
m= mass of the body
g= acceleration due to gravity
h= height of body
Thus if the masses of two bodies are same, the one with greater height possess greater potential energy.
Answer:
See explanation
Explanation:
In chemistry, the idea of "like dissolves like" is of utmost importance. A substance is only soluble in another with which it can effectively interact.
We must note that to be "soluble" means that the solute actually interacts effectively (dissolves) in the solvent.
However, vinegar is a polar substance while oil is a non polar substance hence the two can not effectively interact. That is, the vinegar can not dissolve in oil.
The two will separate into two phases upon standing. Therefore, the bottle of salad dressing made with oil and vinegar must be shaken in order to mix the two thoroughly before it is used.
Answer : The distance covered by slow snail in 24 hours is 
Explanation :
As we are given that the a slow snail can travel 2.2 cm in 1 minute. Now we have to calculate the distance covered by slow snail in 24 hours.
First we have to convert 24 hours in minutes.
Conversion used : (1 hour = 60 minutes)
As, 1 hour = 60 minutes
So, 24 hour = 24 × 60 minutes
= 1440 minutes
Now we have to calculate the distance covered by slow snail in 24 hours.
In 1 minute, the distance covered by slow snail = 2.2 cm
In 1440 minute, the distance covered by slow snail = 1440 × 2.2 cm
= 3168 cm
= 
Now we have to convert 'cm' into 'pm'.
Conversion used : 
As, 
So, 
Therefore, the distance covered by slow snail in 24 hours is
