PLEASE HELP I NEED IT DONE BY OCTOBER 2ND Tila mixes 15 milliliters (mL) of oil with 5 ml of vinegar to make salad dressing.

Drag the bar to graph the volumes of the vinegar and the oil before mixing. Drag the bar to graph the volume of the salad dressing after mixing.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

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.
