Entropy of a reaction can be calculated as:
S_{reaction}=nS_{product}-mS_{reactant}
Where, n is coefficient of products
m is coefficient of reactants
Here by comparing all the reactions it was found that that the entropy increases in only reaction 1 . as in it ,
S_{reaction}=nS_{product}-mS_{reactant}
S_{reaction}=2S_{product}-1S_{reactant}
Found to be greater than other equations.
Answer:12 cm^3 becoz as per Gay-Lussac law
H2+Cl2---. 2HCl thus ratio is 1:1:2
Explanation:
Answer:
Ozon prevents us from UV rays of the sun. Ozone hole means that UV rays are entering the Earth. This results in cancer.
Explanation:
Chlorofluorocarbons are causing this
The solution for this problem is:
Let x = speed of wind
Speed of plane with the wind = x + 100
Speed of plane against the wind = 100 -x
We will be using the formula for distance which is (Rate)(Time), getting the formula for time would be distance/rate Time to travel 600 miles with the wind = Time to travel 400 miles against the wind 600/(x + 100) = 400/(100 - x)
400(x + 100) = 600(100 - x)
400x + 40000 = 60000 - 600x
1000x = 20000
x = 20000/1000
x = 20 mph
Answer: Strictly a laboratory analysis and can only be done using the data obtained during analysis
Explanation:
To find a solution to this problem, you need to use the data collected during the lab work. A guide could be finding the possible forms of hydrated copper chlorides in reference books. Since it's also a lab work, you can definitely compare your data with lab mates.
The formula CuxCly.zH₂O and its name chloride hydrate already gives you an idea of the possibilities of the value of the integers, hence you can take a good guess for the identity of the unknown salt and calculate the theoretical formular weight for it. From the that you can proceed to also find the mass of water and copper from your lab analysis.
