in order to produce 3 moles of o2 how many moles of NaClO3 are required
Answer:
2 moles NaClO3
Explanation:
2NaClO3 --> 2NaCl + 3O2
moles NaClO3 = 3 moles O2 x (2 moles NaClO3/3 moles O2) = 2 moles
conversion factor: 2 moles NaClO3 = 3 moles O2
In order to produce 3 moles of [tex]O_{2}[/tex], the chemical reaction needs to be balanced. the required number of moles of [tex]NaClO_{3}[/tex] are 2.
What is a balanced chemical reaction?When the reactants undergo a chemical reaction, the number of moles on both the reactant and the product side must be balanced.
The chemical reaction of [tex]NaClO_{3}[/tex] is
2 [tex]NaClO_{3}[/tex]⇄2NaCl + 3 [tex]O_{2}[/tex]
On the left side, 2 moles of [tex]NaClO_{3}[/tex] breaks into 2 moles of NaCL and 3 moles of [tex]O_{2}[/tex]. on the right side. Therefore, both side have an equal number of moles of each element.
Hence, two moles of [tex]NaClO_{3}[/tex] is required to produce 3 moles of [tex]O_{2}[/tex].

why do you think the pressure changed as it did when the temperature was increased?
Answer:
La Convención Marco de las Naciones Unidas sobre el Cambio Climático (CMNUCC) en su Artículo 1, lo define como ‘un cambio de clima atribuido directa o indirectamente a la actividad humana que altera la composición de la atmósfera mundial y que se suma a la variabilidad natural del clima observada durante períodos de tiempo comparables’. La CMNUCC distingue entre ‘cambio climático’ atribuido a actividades humanas que alteran la composición atmosférica y ‘variabilidad climática’ atribuida a causas naturales.
Los científicos han encontrado evidencias de que el clima en el planeta está cambiando a un ritmo más acelerado de lo esperado y que nuestras actividades ligadas a la producción, extracción, asentamiento y consumo, son la principal causa de este aceleramiento en el cambio.
El mayor problema de un cambio acelerado en el clima es que nuestras sociedades no están preparadas para asumir los cambios que esto nos pueda traer: derretimiento de las masas glaciares y nevados que abastecen acueductos, cambios en los ciclos de floración y fructificación de las plantas de cultivo, ascensos en el nivel de los mares donde hay mucha población viviendo, mayor ocurrencia y fuerza en lluvias, sequías, huracanes, heladas y granizadas en áreas urbanas y rurales, entre otros fenómenos que sin duda reducen nuestra calidad de vida.

Answer:
8.15 L I2
Explanation:
So, I have the balanced equation of: 2CuBr2 +4KI → 2CuI + 4KBr + I2
Now, we do:
241.6g / 1 mol KI / 1 mol I2 / 22.4 L
--------------------------------------------------------- = 8.15 L I2
/ 166g KI / 4 mol KI / 1 mol I2
