The answer we be C. which is karst topography.
Answer:
Systems move from ordered behavior to more random behavior.
Explanation:
Entropy refers to the degree of disorderliness in a system. The second law of thermodynamics can be restated in terms of entropy as follows; “any spontaneous process in any isolated system always results in an increase in the entropy of that system.''(science direct)
According to this law, systems tend towards a more disorderly behaviour (increase in entropy) hence the answer given above.
Answer:
ratio is 5Fe2+/1KMnO4
Explanation:
You can find the ratio using the coefficients of the known and unknown variables. This will shift the answer for your calculations so make sure to include it. without the mole ratio step, you can not compare 2 molecules or elements.
Answer:
See figure 1
Explanation:
For this question, we have to remember that in the lewis structures all atoms must have<u> 8 electrons</u>. And each atom would have a different value of <u>valence electrons</u>:
Carbon => 4
Oxygen=> 6
Hydrogen=> 1
Additionally, for the <u>hybridizations</u> we have to remember that:
=> 4 single bonds
=> 1 double bond
=> 1 double bond
With this in mind, the formaldehyde and formic acid would have carbons and the ethanol an carbon.
Finally, for the oxidation state. We have to remember that <u>if we have more bonds with oxygen, we will have more oxidation</u>. Therefore, the carbon that has more oxidation is the one in the formic acid (we have several bonds with oxygen).
See figure 1
I hope it helps!
The reaction for magnesium iodide when put into water is as below
MgI2(s) → Mg^2+(aq) + 2I^-(aq)
when magnesium iodide but into water it dissociate/ ionize completely into Mg^2+ and 2l^- ions. Magnesium iodide dissociate/ionize completely because magnesium iodide is a strong electrolyte which dissociate/ ionize completely into their ions when it is put into water .
