Answer:
(e) -6.1 J/K
Explanation:
Step 1: Given data
- Heat of fusion of ice (ΔH°fus): 333.5 J/g
Step 2: Calculate the heat (Qfreezing) required to freeze 5.0 g of water
We will use the following expression.
Qfreezing = -ΔH°fus × m
Qfreezing = -333.5 J/g × 5.0 g = -1.7 × 10³ J
Step 3: Calculate the entropy change (ΔS°) at 0 °C (273.15 K) and 1 atm
We will use the following expression.
ΔS° = Qfreezing/T
ΔS° = -1.7 × 10³ J/273.15 K = -6.1 J/K
Scientists are able to detect an El Niño<span> event and its effects on the climate through a variety of technological and natural sciences. One of these natural sciences is dendrochronology, or the study of tree rings. Dendrochronologists study the rings of a tree in order to understand climatic conditions during specific time periods. Thin rings often indicate drier seasons while fatter rings indicate rainy seasons. Depending on where the tree is, scientists can see past El </span>Niño<span> events in trees that exhibit signs of much rainier or drier seasons that normal.</span>
Answer:
cubic measurements
Explanation:
i.e. cubic meter or cubic centimeter
Explanation:
Transfer of mass A into stagnant film B depends on the availability of driving force.
Whereas driving force is the pressure difference at the surface of A and the bulk.
As, 
Therefore, putting the given values into the above formula as follows.
= 
= 0.132 
Thus, we can conclude that the flux of A from a surface into a mixture of A and B is 0.132
In chemistry, there is a common note that says, "Like dissolves like".
This pertains to the concept that polar substances can dissolve only other polar substances. Also, nonpolar substances are also only able to dissolve nonpolar substances.
Polarity of the substance depends primarily on the type of bond and the difference in electronegativity.
Water is a polar substance while vegetable oil is not. From the concept presented above, it may be concluded that water will not be able to dissolve the vegetable oil and the assumption is logical.
