My view point is that i disagree and that the rules are completely different
<span>You can find
the number of moles in equilibrium if you got the chemical reaction correctly. Make
sure that you got the exact chemical formula of the substance that is reacting
and the yielded product. If you got them, balance the chemical reaction. If the
chemical reaction is balanced, the system is in equilibrium. You can find the
number of moles in equilibrium at the coefficients of the chemical substances
you are balancing. For example, N2 + 3H2 -> 2NH3. The number of moles of N2
is 1, H2 is 3 and NH3 is 2.</span>
It is an example of how the boys environment affected him, making him an outlier to what should typically happen. Hope this helps!
Answer is: the third reaction.
Elements in this chemical reaction do not change their oxidation number. Hydrogen has oxydation number +1, sulfur oxidation number is +6, oxygen has oxidation number -2 and barium has +2 on both sides of chemical reaction. In other reactions elements change their oxidation numbers.
Answer:
A
Explanation:
Arsenic is in the same group as Nitrogen - group 5. They all have 5 valence electrons in their outermost shell. To achieve its most stable state - 8 valence electrons (octet rule - elements are most stable when the entire shell is filled) - arsenic needs to gain 3 electrons. Since electrons have a negative charge, the charge of an As ion would be -3.
Try observing the periodic table and how many valence electrons that each element has. From there, you can determine the charges of the elements lithium and strontium. You can guess, I'll help you with those once you attempt to find the charge of those ions.
