Because the decomposition is the reverse process of the formation.
Enthalpy is a function of state, which means that the value dependes only on the state and not the pathway.
Then the change of enthalpy is the same in magnitude for both cases but in formation the change is netavie (releases energy) and in the other is postive (absorbs energy).
Answer:
iron deficiency (anaemia)
Explanation:
when there is lack of iron it causes anaemia
Cobalt is a solid, it’s a hard metal, it’s magnetic and brittle.
Procaine hydrochloride ( = 272.77 g/mol) is used as a local anesthetic. Calculate the molarity of a 4.666 m solution which has a density of 1.1066 g/ml.
molarity = Moles of solute / volume of solution
Molarity = m d / [ 1 + (mW / 1000)]
Molarity = 4.666 X 1.1066 / [ 1 + (4.666 X 272.77 / 1000)]
Molarity = 5.16 / 2.272= 2.271 M
The change happening here is called a chemical change. ^-^
