Answer: We take 20 ml of 1.0 M fruit drink and add 80 ml of water to get 100 ml of 0.2 M solution.
Explanation:
According to the neutralization law,
where,
= molarity of stock solution = 0.2 M
= volume of stock solution = 100 ml
= molarity of resulting solution = 1.0 M
= volume of resulting solution = ?
Now put all the given values in the above law, we get the volume of resulting solution.
Therefore, the volume of 1.0 M required is 20 ml.
We take 20 ml of 1.0 M fruit drink and add 80 ml of water to get 100 ml of 0.2 M solution.
Answer:
-375.9_KJ/(mol)
Explanation:
H(T2 ) ≈ H(T1)+CPΔT
Specific heat of Carbon is 0.71 J/g K.
At 283.15 the heat capacity is 37.12 J/(mol*K)
Kirchhoff's law
H(T2 ) ≈ H(T1)+CPΔT
Where
H(T1) and H(T2 ) are the heat of formation of CO2 at temperatures T1 and T2
CP is the heat capacity
Thus we have and ΔT is the temperature change
H(T2 ) ≈ -393.51×10^3+CP×(500-25)
= -393.51×10^3+37.12×(500-25)
= -375878 J/(mol)
= -375.9KJ/(mol)
Answer:
One has a bunch of chemicals and one doesnt physical is hands on chemical is watching
Explanation:
I just know my science
Wet ashing • Wet ashing is primarily used in the preparation of samples for subsequent analysis of specific minerals . It breaks down and removes the organic matrix surrounding the minerals so that they are left in an aqueous solution.
Hope this helps!
