Acoffee-cup calorimeter initially contains g water at . potassium bromide ( g), also at , is added to the water, and after the dissolves, the final temperature is . calculate the enthalpy change for dissolving the salt in j/g and kj/mol. assume that the specific heat capacity of the solution is and that no heat is transferred to the surroundings or to the calorimeter
most metamorphic processes take place a few kilometers below earth's surface. metamorphic processes result due to intense heat and high pressure below the earth's surface. also, metamorphism can occur on two scales, contact and regional.
an ionic compound consists of a metal and a non-metal.
oxygen and fluorine are non-metals.
sodium and aluminium are non-metals.
calcium is a metal and chlorine is a non-metal.
nitrogen and sulfur are non-metals.
thus, the answer is c.
ionic bonds \
the result is a bond where the electron pair is displaced toward the more electronegative atom.
