PLZZZ HELP!! Metals bond with halogens to form colorless metal halides. During an experiment, bromine water
was added to a solution of potassium iodide. A record of the experiment is shown.
Experimental Record
Reactants Color of Reactants Color of Reactants after Mixing
Br2
Light orange solution
Deep brown colored solution is formed
KI
Colorless solution
Which of the following conclusions can be made about this chemical reaction based on the data?
lodine is more reactive than bromine.
O Potassium iodide and bromine do not react.
O Potassium metal is formed from a single replacement reaction.
lodine is deep brown in color and is formed from a single replacement reaction.

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.
