Answer:
The reactión is exothermic
Explanation:
The change in enthalpy follow the next equation:
ΔH = ΔH(products) - ΔH(reactants)
If the products have a lower enthalpy means that ΔH<0; this mean that the reaction gives heat to the environment
The eight-element periodicity found in the Periodic Table is related to the number of electrons in the outermost energy level of the atoms that make up each element
this statement is true
A because it is the only one that a formula doesnt tell
Answer:
C10H15N is the chemical equation for methamphetamine
Ammonium iodide, or NH₄I, is a salt. Since all salts are strong electrolytes, when ammonium iodide is dissolved in water, it would dissociate into ammonium ions and iodide ions. Hence, the major species present would be: <em>NH₄⁺ and I⁻ ions</em>.
