A grey coloured rock with amphibole and intermediate plagioclase like an andesine would classify as an intermediate rock by Bowen's Reaction Series and by the classification of igneous rocks would probably be like a diorite which is intermediate between a gabbro and a granite. A diorite essentially has no quartz but has the silicates amphibole (like hornblende), mica perhaps a little pyroxene and andesine plagioclase.
Answer:
A restoration
Explanation:
the action of returning something to a former owner, place, or condition.
<u>Answer:</u> The internal energy change for the reaction is -2850 J
<u>Explanation:</u>
- <u>Sign convention of heat:</u>
When heat is absorbed, the sign of heat is taken to be positive and when heat is released, the sign of heat is taken to be negative.
- <u>Sign convention of work:</u>
Work done for expansion process is taken as negative and work done for compression is taken as positive.
According to the First law of thermodynamics,

where,
= internal energy
q = heat absorbed or released = -2290 J
w = work done = -560 J
Putting values in above equation, we get:

Hence, the internal energy change for the reaction is -2850 J
A solute rises the boiling point of a solution, in direct relation with the number of particles added to the solution. Sucrose remains a molecule, does not separate into anything. NaCl gives Na+ + Cl-.
<span>Molar mass of sucrose is 12*12+22*1+11*16=144+22+176=342 </span>
<span>105g sucrose is 105/342=0.3moles ---> 0.3 moles of particles (molecules) </span>
<span>Molar mass of NaCl is 23+35.5=58.5 </span>
<span>35 grams of NaCl is 35/58.5=0.598 ----->0.598*2=1.1974 moles of particles (ions, Na+ and Cl-) </span>
<span>So, 35 grams of sodium chloride in 500 grams of water will have a higher boiling point</span>
