The postulate of Dalton's atomic theory which is a result of the law of conservation of mass is: Atoms are indivisible particles, which can neither be created nor destroyed in a chemical reaction.
Respuesta:
2400 mL
Explicación:
Paso 1: Información dada
- Volumen de solución: 3 L (3000 mL)
- Concentración de naranja: 20 % v/v
Paso 2: Calcular el volumen de naranja
La concentración de naranja es de 20 % v/v, es decir, cada 100 mL de solución hay 20 mL de naranja.
3000 mL Sol × 20 mL Naranja/100 mL Solución = 600 mL Naranja
Paso 3: Calcular el volumn de agua
El volumen de soluciónes igual a la suma de los volúmenes de naranja y agua.
VSolución = VNaranja + VAgua
VAgua = VSolución - VNaranja
VAgua = 3000 mL - 600 mL = 2400 mL
In order to compare the two elements, one must take note of
its placement in the periodic table. As you go down a group in the periodic
table, the metallic property increases. Thus in the problem, Antimony has a
more metallic behavior than Arsenic so that already crosses out statement A and
B from the choices since it is untrue. The number of electron shells meanwhile
decreases as you go down the group. Therefore the answer would be Arsenic has a
more nonmetallic behavior than antimony because arsenic’s atoms have fewer
electron shells.
