What is the enthalpy change for converting 10.0 g of ice at -25.0°C to water at 80.0°C. The specific heats of ice, water, and steam are 2.09 Jg-1°C-1, 4.18 Jg-1°C-1, and 1.84 Jg-1°C-1, respectively. For H2O, △Hfus = 6.01 kJ/mol, and △Hvap = 40.67 kJ/mol

How are ionic bonds formed and what is the attractive force within an ionic bond

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
