Among solids, liquids, and gases, solids generally have the highest entropy because solid particles are the least mobile, and entropy is inversely related to mobility of particles.
Answer:
9kg
Explanation:
According to Newton's second law, Force=Mass x Acceleration.
Since we have the Force and the Acceleration, we can plug the values in and solve for mass using this equation:
90N = Mass x 10m/s
Divide both sides by 10:
90/10=Mass x 10/10
Mass = 9
The Mass of the object is 9kg.
Hope this helped!
You cannot change the subscripts inside the compounds but you can in fact add a coefficient in front of them to properly balance the equation.
Answer:
Biphenyl
Explanation:
The reaction of bromo benzene with magnesium-ether solution yields a Grignard reagent.
The byproduct of this reaction is biphenyl. It is formed when two unreacted bromobenzene molecules are coupled together.
Hence, It is advised that the bromobenzene solution be added slowly to the magnesium-ether solution so that it isn't present in a high concentration, thus reducing the amount of biphenyl by-product formed.
I think the question is incomplete as we need initial temperature to get the new temperature. but you can use equation Q=mc0 for guidelines
Q= energy
m= mass of solution
c= specific heat capacity of. solution
0= final temperature- initial temperature
