Consider the reaction.

At equilibrium, the concentrations of the different species are as follows.
[NH3] = 0.105 M
[N2] = 1.1 M
[H2] = 1.50 M
What is the equilibrium constant for the reaction at this temperature?
K=0.105*0.105/1.1*1.50*1.50*1.50
=0.011025/3.7125
=0.002959
Yes the cake is a lie
But the real question is, is it still there? Is the cake made? Glados isn't a very nice person, but i'm sure she at least made the cake incase things went her way.
In an ionic compound, the net ionic charge refers to the overall charge on the compound. It is the sum of the charges of all the ions present in the compound.
To determine the net ionic charge, you need to know the charges of the individual ions that make up the compound. In an ionic compound, one or more positively charged ions, known as cations, combine with one or more negatively charged ions, known as anions, to form a stable structure. The net ionic charge is the result of the attractive forces between these oppositely charged ions.
To find the net ionic charge, you should first determine the charges of the ions involved. This can be done by referring to the periodic table or by knowing the common charges associated with different elements. For example, alkali metals like sodium (Na) typically have a charge of +1, alkaline earth metals like magnesium (Mg) have a charge of +2, and halogens like chlorine (Cl) usually have a charge of -1.
Once you know the charges of the ions, you can balance them to achieve a neutral overall charge. This means that the total positive charge from cations should be equal to the total negative charge from anions. The net ionic charge is what remains after balancing these charges.
Regarding your second question, an -ide ending generally indicates a compound formed between a non-metal and a metal. Non-metals tend to gain electrons to achieve a stable electron configuration, resulting in a negative charge, whereas metals tend to lose electrons, resulting in a positive charge. When a non-metal and a metal combine, the non-metal is typically named with an -ide ending. For example, chloride (Cl-) is the -ide form of chlorine when it combines with a metal. Other examples include fluoride (F-), bromide (Br-), and oxide (O2-).
Remember that these are general rules, and there are exceptions to these naming conventions. It is always a good idea to consult a reliable source or reference for specific compounds and their naming.
