How many moles of HNO3 can be produced from 115 g of NH3? The reactions involved are given below. Assume
each reaction is 100% efficient.
4NH3 + 502 → 4NO + 6H2O
2NO+ O2 → 2NO2
3NO2 + H2O → 2HNO3 + NO

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.

since electrons are negative the answer is neagtaive

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them  

catya your not at all which answer i've seen you do this on another question!
