Earlier in the lesson, you determined that the enthalphy for magnesium combustion could be computed using Hess’s law. The formula derived from the reaction equations was: Delta H shown in orange equals delta H 1 in green minus delta H 2 in purple plus delta h 3 in blue.

The enthalpy of the magnesium combustion is
kJ/mol.

Amonoprotic acid is an acid that donates a single proton to the solution. suppose you have 0.140 g of a monoprotic acid dissolved in 35.0 ml of water. this solution is then neutralized with 14.5 ml of 0.110 m naoh. what is the molar mass of the acid?

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.

Chemical energy is a form of a. kinetic energy only. b. both potential and kinetic energy. c. neither potential nor kinetic energy. d. potential energy only. reset
