Answer from: ggperez68

16.9 kPa is the partial pressure or pressure produced by a mixture of gases having total pressure of 93.6 kPa.

Explanation:

Data given:

mixture of hydrogen, helium . neon and argon gases with total pressure = 93.6 kPa

partial pressure of helium, pHe = 15.4 kPa

partial pressure of neon gas, pNe = 25.7 kPa

partial pressure of Argon gas, pAr = 35.6 kPa

partial pressure of hydrogen gas. pH =?

Here, Daltons law of partial pressure will be applied"

Ptotal = pHe + pNe + pAr +pH

Ptotal - pHe -pNe -pAr = pH

93.6 - (15.4+25.7+35.6) = pH

pH = 16.9 kPa

pressure exerted by hydrogen gas individually is 16.6kPa.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is $1s^{2}2s^{2}2p^{6}3s^{1}$ and electronic configuration of phosphorous is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{3}$ .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

$3na + p \rightarrow na_{3}p$

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

Electrons are transferred from atoms of to atoms of this transfer makes the sodium atoms and the

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
