Will give ! (only for correct answers) for each of the following reactions, identify all of these: a. oxidized species b. reduced species c. oxidizing agent d. reducing agent i) 2 fe (s) + 3 cl2 (g) --> 2 fecl3(s) ii) mg (s) +2 h2so4 (aq) --> mgso4 (aq) + so2 (g) + 2 h2o (l) iii) 2 mg (s) + o2 (g) --> 2 mgo (s)

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
