Scientists noticed that the frogs in smith lake were much larger than the frogs in lake martin. smith
lake is non-polluted, fresh water, whereas the water quality in lake martin is low due to contamination
with pesticides. in the experiment, tadpoles of the same age were collected, along with the same amount
of water from each reservoir. the tadpoles were allowed to mature for 3 weeks and their growth was
compared

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.

answer: mole of the gas

answer: mole of the gasexplanation:
