Use the data in the simulation to find the Ka value of HF, hydrofluoric acid

Chemistry

Dmitry_Shevchenko [17]3 years ago
4 0
We need to find the Ka value of HF. First, set up the balanced chemical equation:

HF ===> H+ + F-

The formula for the Ka value of an acid is

Ka = [concentration of products] / [concentration of reactants]

Ka = [H+] [F-} / [HF]

So if we are given the concentration of the products and reactants, we will be able to solve for the Ka value of HF.

What makes a metal and a non metal most
Katarina [22]

Answer:

Explanation:

The reactivity of elements in the periodic table is based on the number of electrons in there outermost shell. Elements (metals) that have few electrons in there outermost shell are highly reactive because it is easier to lose fewer number of electrons (in the outermost shell during a reaction) than to lose more electrons in the outermost shell - thus metals that have one electron in there outermost shell are most reactive and are more reactive than those that have two electrons in there outermost shell. Hence, metals in group 1 are the most reactive metals because they all have one electron in there outermost shell.

Non-metals that have fewer electrons to complete there octet configuration are highly reactive because it is easier to gain fewer number of electrons (in the outermost shell during a reaction) than to gain more number of electrons - thus nonmetals that have seven electrons in there outermost shell are more reactive than nonmetals that have six electrons in there outermost shell. Hence, nonmetals in group 17 are the most reactive nonmetals because they contain seven electrons and have just one electron left to complete there octet configuration.

What is an input force?
nataly862011 [7]
Force is a pull or a push acting on a body at rest or in motion resulting from its interaction with another body. Input force is the force that you put on a machine while Output force is the force the machine exerts on an object. The output distance is when the output force moves the machine a certain distance while the input distance is when the input distance is when the input force moves the machine a certain distance.
