What volume, in L, of 0.0751 M LiOH solution is required to produce 70.9 g of water. 2LiOH(aq) + H2SO4(aq) → 2H2O(l) + Li2SO4(aq)

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

the correct answer is:

a. formation of precipitation

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.
