Which of the following statements is TRUE regarding the radioactivity of isotopes? A) If any isotope of a given element is radioactive, then all isotopes of that element will be radioactive

B) The radioactivity of a particular atom is not dependent on which isotope of an element that atom is

C) Some isotopes of an element can be stable while others are radioactive

D) If any isotope of a given element is stable, then all isotopes of that element will be stable

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

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

the right answer is c i just did the question.

i think is conclusions.i think so
