Answer: The freezing point of a 0.765 m solution of nitrobenzene in naphthalene is 
Explanation:
Depression in freezing point is given by:
= Depression in freezing point
i= vant hoff factor = 1 (for non electrolyte such as nitrobenzene)
= freezing point constant = 
m= molality = 0.765
Thus the freezing point of a 0.765 m solution of nitrobenzene in naphthalene is
Answer:
1) B. increases
2) B. greater
3) C. Both A and B are correct
4) Activation energy
Explanation:
The rate of a chemical reaction is depend on temperature. If temperature increases, the chemical reaction also increases and vice versa. Fast reaction means which is completely in less time. So atoms in fast reaction have great activation energy and slow reaction have less activation energy. Collision occurs when the particles have energy to move and they collide in proper direction.
Answer:
Explanation:
E = (hc)/(λ)
E = (6.624x10^(-27))Js x ((3×10^8)ms^(-1)) /
(77.8x10^(-9)m)
E = 2.55 x 10^(-11) J
Answer:
2,751 Meters.
Explanation:
0.86 + 22.4 + 4.25 = 27.51 km.
Convert that to meters which gives you 2,751 meters.
Answer:
B. 1 +8 > 2 + 4
Explanation:
Hello!
In this case, since inequalities show how a number is different, greater or less than, to an other, considering the given options, just B. 1 +8 > 2 + 4 is an inequality because if we solve the operation we obtain:
9 > 6
Which means that nine is greater than 6.
Best regards!
