1s22s22p63s23p64s23d104p6. This ion is a(n) . What is the chemical symbol of the noble gas this ion is isoelectronic with?
leonid [27]

1) Answer is: This ion is Br⁻ (bromine anion).

This ion has 36 electrons, because it has charge -1 (atom gain one electron), its atom has 35 electrons and 35 protons (atomic number 35). Element with atomic number 35 is bromine.

Electron configuration of ion with a charge of -1:                                                    ₃₅Br⁻ 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶.

2) Answer is: chemical symbol of the noble gas is Kr (krypton).

Isoelectronic atom or ion has the same number of valence electrons. Krypton has 36 electron and 36 protons (atomic number 36).

how to calculate the formula mass of H2S2, HFO2 an keep at least one decimal place in atomic masses from the periodic table
weqwewe [10]
H = 1.008
S = 32.066
F = 18.998
O = 15.999

(1.008 x 2) + (32.066 x 2) = 66.148 g/mol

(1.008) + (18.998) + (15.999 x 2) = 52.004

The boiling point of a substance is known to be 293°C. What is the vapor pressure of that substance at 220°C?
love history [14]

Explanation:

The boiling point of a substance is 293°C.

The boiling point is the temperature at which the vapor pressure of a liquid becomes equal to the atmospheric pressure.

So, at the boiling point:

The vapor pressure =atmospheric pressure = 1 atm.

To get the vapor pressure of the substance at 220°C is definitely less than 1 atm.

Since, as the temperature increases, the vapor pressure of the liquid increases.
