2. caco3 -> cao + co2
limestone -> calcium oxide + carbon dioxide
Answer:
Azucar, bicarbonato de sodio, lavandina, vinagre, amoniaco.
Explanation:
Podemos numerar estos compuestos
Azucar → Sacarosa → C₁₂H₂₂O₁₁
Lavandina → Hipoclorito de sodio → NaClO
Vinagre → Ácido acético → CH₃COOH
Bicarbonato de sodio → NaHCO₃
Amoníaco → NH₃
The balanced reaction:
<span>4Na + O2 = 2Na2O
We use the relation of the substances and the amount of sodium to determine the theoretical yield of the reaction. This yield is the amount produced if all the reactant is consumed.
2.55 mol Na (2 mol Na2O / 4 mol Na) ( 61.98 g / 1 mol ) = 79.02 g Na2O
Percent yield = 75.0 / 79.02 x 100 = 94.91%</span>
La energía térmica es la energía que proviene del calor.
De nada ;)
As atomic number increases within group 15 on the periodic table, atomic radius increases only.
