How do neutral metal atoms form ions?​
stira [4]

Answer:

Neutral atoms can be turned into positively charged ions by removing one or more electrons. ... Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons. By adding one more electron we get a negatively charged Cl- ion with a net charge of -1.

A reaction between liquid reactants takes place at −10.0°C in a sealed, evacuated vessel with a measured volume of 45.0L. Measur
maks197457 [2]

Answer: 0.0624 atm

Explanation:-

According to the ideal gas equation:

PV=nRT

P = Pressure of the gas = ?

V= Volume of the gas = 45.0 L

T= Temperature of the gas = -10.0°C = 263 K    0^00C=273K

R= Gas constant = 0.0821 atmL/K mol

n= moles of gas

Moles of gas=\frac{\text{ given mass}}{\text{ molar mass}}= \frac{19.0g}{146g/mole}=0.130moles

P=\frac{nRT}{V}=\frac{0.130\times 0.0821\times 263}{45.0}=0.0624atm

The pressure of sulfur hexafluoride gas in the reaction vessel after the reaction is 0.0624 atm
