Calcium carbonate can be decomposed by heating: CaCO3 - CaO + CO2
Galina-37 [17]

Answer: 13.888g

Explanation:

CaCO3 —> CaO + CO2

From the equation above, 1mole of CaCO3 produces 1mole of CaO. Since the answer is to be expressed in grams, let us covert this mole to grams. This is illustrated below:

MM of CaCO3 = 40 +12 + (16x3) = 40 + 12 + 48 = 100g/mol

MM of CaO = 40 + 16 = 56g/mol

From the equation,

100g of CaCO3 produced 56g CaO

Therefore, 24.8g of CaCO3 will produce Xg of CaO i.e

Xg of CaO = (24.8 x 56) / 100 = 13.888g

Therefore, the theoretical yield of CaO is 13.888g

Question 1<br> Review<br> Which laboratory equipment is correctly paired with the unit it measures?
Bad White [126]

Answer:

Cilindros graduados

Explanation:

Son una herramienta de medición primaria para el volumen de un líquido, y tiene varias marcas hacia arriba y hacia abajo a lo largo del contenedor con incrementos específicos. Los cilindros graduados vienen en muchos tamaños; entre más pequeños sean de diámetro, más específicas serán las mediciones de volumen. Al leer el volumen de un cilindro graduado, notarán que el líquido parece tener una muesca; el líquido alrededor de los bordes será más alto que el líquido en el centro, inclinándose hacia abajo como los lados de un trampolín cuando alguien está parado en el medio. Esto se llama el menisco. Alineen el punto más bajo del menisco con la marca más cercana, manteniendo el nivel del cilindro para leer correctamente el volumen.
