Your first step is determining how many gram of KCl are in every mole of KCl. This can be done by simply looking at K and Cl's atomic mass on the Periodic Table. You add K's atomic mass (39.1g) with Cl's atomic mass (35.45g) to determine that the mass of one mole of KCl is 74.55g. Because you have 10 moles of KCl you multiply 74.55g by 10 to reach your answer of 745.5g.
<span>Determining the number chloride molecules that will result from this reaction requires we first determine the number of moles of arsenic and the number of moles of chlorine on hand.
1.587 grams of arsenic divided by its atomic weight of 74.92 grams per mole results in 0.0212 moles.
We do the same for chlorine. 2.755 grams of chlorine divided by 35.45 grams per mole gives us 0.106 moles.
0.106 moles divided by .0212 moles equals 5; therefore, the simplest formula of the chloride produced will be AsCl</span>₅<span>.</span>
Answer:
Anode half reaction equation:
Ni(s)------> Ni^2+(aq) + 2e-
Explanation:
Looking at the values of reduction potential given in the question, Ni2+|Ni half cell has a more negative reduction potential than the Fe3+|Fe2+ half cell. The more negative the reduction potential of a half cell, the more its tendency to act as the anode. Hence based on the half cell reduction potentials presented in the question, Ni2+|Ni is the anode while the other is the cathode.
Answer: All organic compound depends on H-bonding with water. more stronger H-bonding with water more will be soluble.
Explanation:
1. It depends primarily upon the function groups of that compound. It also depends on the size of the compound.
2. some organic compound which soluble in water for example: alcohols, ethers, carboxylic acids. Because of the functional groups attached to the organic structure (the C-H backbone) are what effect the solubilities.Like carboxylic acids and alcohols form hydrogen bonds with the water, helping to solubilize it.
3. Take alcohols for example: methanol, ethanol, and isopropanol are all completely soluble in water. By the time you get to butanol and some of the larger alcohols, including those with more complex structures, they tend to be less soluble.
Answer:
2
Explanation:
I think this because its common sense, you need an energy sorce to create light.
