ΔH for this reaction : -2668.4 (exothermic)
<h3>Further explanation </h3>
The change in enthalpy in the formation of 1 mole of the elements is called enthalpy of formation
The enthalpy of formation measured in standard conditions (25 ° C, 1 atm) is called the standard enthalpy of formation (ΔHf °)
(ΔH) can be positive (endothermic = requires heat) or negative (exothermic = releasing heat)
The value of ° H ° can be calculated from the change in enthalpy of standard formation:
∆H ° rxn = ∑n ∆Hf ° (product) - ∑n ∆Hf ° (reactants)
you can search the value of ΔHf on the internet
∆H ° rxn =( ∆H Al₂O₃+∆H AlCl₃+3.∆H NO + 6.∆H H₂O)-(∆H Al+∆H NH₄ClO₄)
Answer:
Organic fertilizers are those fertilizers that are not artificially produced but are natural and has carbon in them.
Fertilizers in the broad term are used to provide nutrient to the soil and boost growth of crops.
Some of the advantages of organic fertilizers to inorganic fertilizers are:
They do not make crusts on the soil, unlike inorganic fertilizers.
They help add structure to the soil because of the good water movement into the soil
They are easier on the soil because they feed good microbes.
The names of some ionic compounds include the charge of the metal ion while others do not because there are ionic compounds that are able to form more than one type of ion especially for metals and these compounds should be distinguished properly to avoid confusion. For instance, the metal cation of iron, we have Fe2+ and Fe3+. Ionic compounds with metal cations have a charge that is invariant from a compound to another does not include the charge of the cation. However, for ionic compounds of a metal with a charge that would vary in different compounds should include the charge of that particular metal cation.
this is an inert reaction.
NaCl + NH4Cl ---> NaCl + NH4Cl
The products would contain the same molecules as the reactant side due to the fact that both reactants contain Chloride.
Answer:
Chemicals in fertilizers run off into water and cause algae blooms
Explanation:
Of the answer choices, the ones that have to do with commercial land use are the ones discussing fertilizers. Some commercial land is dedicated to lawn, but commercial farms are a much larger portion of commercial land use. The appropriate choice is, "Chemicals in fertilizers run off into water and cause algae blooms."
