<u>Answer:</u> The equilibrium partial pressure of NO is 0.0034 atm
<u>Explanation:</u>
For the given chemical equation:
The expression of 
for above equation follows:
We are given:
Equilibrium partial pressure of 
= 0.0159 atm
Equilibrium partial pressure of NOBr = 0.0768 atm
Putting values in above equation, we get:
Hence, the equilibrium partial pressure of NO is 0.0034 atm
Answer:
1.09 L
Explanation:
There is some info missing. I think this is the original question.
<em>Calculate the volume in liters of a 0.360 mol/L barium acetate solution that contains 100 g of barium acetate. Be sure your answer has the correct number of significant digits.</em>
<em />
The molar mass of barium acetate is 255.43 g/mol. The moles corresponding to 100 grams are:
100 g × (1 mol/255.43 g) = 0.391 mol
0.391 moles of barium acetate are contained in an unknown volume of a 0.360 mol/L barium acetate solution. The volume is:
0.391 mol × (1 L/0.360 mol) = 1.09 L
Answer: Chemical change
Explanation:
Physical change is a change where there is a change in size , shape etc and no new products are formed.
Chemical change is a change where there is a change in chemical composition as new products are formed.
Example: Formation of soap and glycerin from fat and sodium hydroxide is a chemical change as the chemical bonds are getting rearranged to form new products.
