Answer:
Explanation:
There are two heat transfers involved: the heat lost by the metal block and the heat gained by the water.
According to the Law of Conservation of Energy, energy can neither be destroyed nor created, so the sum of these terms must be zero.
Let the metal be Component 1 and the water be Component 2.
Data:
For the metal:
For the water:
Answer;
Water has the highest normal boiling point and methanol on the other hand has the lowest boiling point.
Explanation;
-The normal boiling point is the temperature in which the vapor pressure of a liquid becomes equal to atmospheric pressure.If the inter-molecular forces are small, the liquid has a high vapor pressure. Little heat energy will have to be added to separate the molecules, so the boiling point will be low.
-Boiling points and equilibrium vapor pressure are inversely proportional, because less heat is required to raise vapor pressure to reach atmospheric pressure.
-Therefore, since water has the lowest vapor pressure, water it has the highest boiling point and since methanol has the highest vapor pressure it has the lowest boiling point.
Answer:
Co(CN)₂
Explanation:
Cobalt (II) cyanide -
The formula for Cobalt (II) cyanide is Co(CN)₂ , it is one of the inorganic compound . It is one of the type of coordination polymer , the compound is used in the many inorganic synthesis and in the homogeneous catalysis .
<u>The major use of Co(CN)₂ is that , it acts as a precursor to the cobalt carbonyl.</u>
<span>You breathe in 100 quintillion of argon every four seconds that you breathe in and breathe out. Argon is a noble gas that is mixed with other things like oxygen, nitrogen, and carbon dioxide in the air. Breathing argon by itself could be dangerous.</span>
