1) mol fraction of gas X= 2/(6+2)=2/8=1/4
2) mol fraction of gas Y= 6/(6+2)=6/8=3/4
3) Partial pressure of X = 1/4*2.1 atm=0.53 atm
4) Partial pressure of Y = 3/4*2.1=1.6 atm
Answer:
325 cm is equivalent to 3250 mm.
Explanation:
In this case, we need to convert 325 cm of copper wire into mm. The conversion from cm to mm is given below :
1 cm = 10 mm
To convert 325 cm to mm, we will use unitary method.
325 cm = 325 × 10 mm
325 cm = 3250 mm
So, 325 cm is equivalent to 3250 mm.
Answer:
The wax
Explanation:
The limiting reactant is the reactant in short supply in a particular reaction. This reactant determines the extent of the reaction. Oxygen in the reaction is the one in excess. As we know that oxygen is free in the atmosphere and it is in excess supply.
After the wax finishes burning the reaction stops and no more production of carbon dioxide, water and energy but oxygen still continues to abound all around.
In order to determine the amount of carbon dioxide and water that would be produce, we simply use the amount of wax to relate with them.
The answer is D. To put it simply, all atom wished to become stable. The only way for that is to obtain an octet structure where the outermost shell would have 8 electrons, thus being full.
