Answer:
C. 0.04 moles per cubic decimeter.
Explanation:
The molar mass of the Iodine is 253.809 grams per mole and a cubic decimeter equals 1000 cubic centimeters. The concentration of Iodine (), measured in moles per cubic decimeter, can be determined by the following formula:
(1)
Where:
- Mass of iodine, measured in grams.
- Molar mass of iodine, measured in grams per mol.
- Volume of solution, measured in cubic decimeters.
If we know that , and , then the concentration of iodine in a solution is:
Hence, the correct answer is C.
Answer: The value of equilibrium constant for the given reaction is,
Explanation:
The given chemical equation is:
;
We need to calculate the equilibrium constant for the chemical equation, which is:
;
If the equation is revered then the equilibrium constant will be the reciprocal of the reaction.
If the equation is half then the equilibrium constant will be square-root of the reaction.
The value of equilibrium constant for the given reaction is:
Hence, the value of equilibrium constant for the given reaction is,
Answer:
When you heat up water, it starts to evaporate slowly into the air. When you fuse two things together, that takes a lot of heat to do. Both of these things are related to heat.
Explanation:
Answer:
Maintenance of homeostasis usually involves negative feedback loops. These loops act to oppose the stimulus, or cue, that triggers them.
All " transuranium elements " ( i.e. an atomic number greater than 92 ) are unstable. Elements in the same family have similar properties. Based on this logic, one would expect seaborgium ( Sg ) to have similar properties to tungsten ( W ), which is directly above it in the same family.Elements of atomic mass 92 and above being most unstable called the transuranium group of elements is found to have many common properties and becomes difficult to judge on the basis of properties. Atomic number is the number of protons in the nucleus of the atom and it describes the chemical property of the elements.
