Answer:
A sulfur ion with a charge of -2 = S⁻²
An iron ion with a charge of +3 = Fe⁺³
A chlorine ion with a charge of -3 = Cl⁻³
Explanation:
Anion:
Anion are formed when an atom gain the electrons.
Representation:
The anion of an atom is showed by adding the number of electrons gained by atom with negative sign as superscript on the symbol of an atom.
Cation:
Cation is formed when an atom lose the electron.
Representation:
The cation of an atom is showed by adding the number of electrons lose by an atom with positive sign as superscript on the symbol of an atom.
A sulfur ion with a charge of -2 = S⁻²
An iron ion with a charge of +3 = Fe⁺³
A chlorine ion with a charge of -3 = Cl⁻³
I believe it’s 164.0878 grams
Answer:
Substances have more kinetic energy in the gas state than in the Solid state.
Gas have more kinetic energy as it flows from here and there.It flows really fast as it have less space between the molecules
Solids have less Kinetic energy as it is hard and can't flow so easily like gas . It has tightly packed molecules
Answer: 8.12 g NaCl
Explanation: Use Avogadro's number to find the number of m
moles of NaCl:
8.24x10²² molecules NaCl / 1 mole NaCl/ 6.022x10²³ molecules NaCl
= 0.14 mole NaCl
Next convert moles to grams NaCl using its molar mass;
0.14 mole NaCl x 58g NaCl / 1 mole NaCl
= 8.12 g NaCl
The development that belongs at the end is genetic engineering.
