Respuesta:
1.50 moles
Explicación:
Paso 1: Escribir la ecuación química ajustada para la descomposición del carbonato de calcio
CaCO₃ ⇒ CaO + CO₂
Paso 2: Calcular los moles correspondientes a 150 g de CaCO₃
La masa molar de CaCO₃ es 100.09 g/mol.
150 g × 1 mol/100.09 g = 1.50 mol
Paso 3: Calcular los moles de CO₂ producidos a partir de 1.50 moles de CaCO₃
La relación molar de CaCO₃ a CO₂ es 1:1.
1.50 mol CaCO₃ × 1 mol CO₂/1 mol CaCO₃ = 1.50 mol CO₂
Answer:
I think the answer is C because I know
B. Light energy and heat energy!
This is because the thermal energy which is the heat. As you know fire heats up and burns, a lit candle would do just the seem. Also the fire is bright enough to light up an area!
Answer:
As nouns the difference between impression and imprint
is that impression is the indentation or depression made by the pressure of one object on or into another while imprint is an impression; the mark left behind by printing something.
