A compound is discovered and its molecular weight is determined to be 526g/mol. however, one of the elements has not yet been id
AfilCa [17]

Sulphur

The missing element is sulphur

Here the compound is composed of  element X and chlorine.

it is given,

XCl (6) ----> 6Cl

mass = 13.1%

it is X and Cl = 100%-13.10%

                     = 86.90%

chlorine = 86.90            

X = 13.10

We assume 100g of sample

so according to the above solved data, in 100g of sample we have 86.90 g of chlorine.

now we split that chlorine into two moles of chlorine.

  • Every mole of sale has 35.45 grams of sales. 2.451 moles of seal are mine after that.
  • We are aware that cl is six times more than X. To find the moles of X, I must divide this number by six.
  • we discover that we have  0.4086 moles of X when we divide this by six.
  • We obtain those moles of X from 13.10 g of X.  
  • Given that Mueller masses grams per mole, I can compute the molar mass.
  • 13.10 grams of X are contained in 0.4086 moles of X.
  • Or, to put it another way, each remote has a molar mass of 32–06 grams.
  • The element with this molar mass is sulfur, as I can see from the periodic table.
  • Okay, so the element we're looking for in this situation is sulfur.

Compare the numbers of protons and electrons in a positive ion with the numbers of protons and electrons in a negative ion.
kow [346]

Answer:

In a positive ion, the number of protons is larger than the number of electrons.

In a negative ion, the number of protons is smaller than the number of electrons.

Explanation:

Each proton carries a positive charge of one unit.

Each elec in tron carries a negative charge of one unit.

In an atom, there are as many protons as electrons. Hence, they are neutral.

However, in a positive ion, there are less negative charge than positive charge. Hence the net charge is positive. That also means that there are fewer negatively-charged electrons than positively-charged protons.

Similarly, in a negative ion, there are more negative charge than positive charge. Hence the net charge is negative. That also means that there are more negatively-charged electrons than positively-charged protons.
