The Iron (III) ion is
The sulfate ion is
Thus when forming the compound iron (iii) sulfate you would need three sulfate ions bonded to two iron ions in order to fill the valency requirement
∴ the formula would be Fe₂(SO₄)₃
Whenever you are adding a number to a radical you must bracket it.
Answer:
F,Cl,N,I,Se,H
Explanation:
polarity increases as electronegativity increases i guess so that is supposed to be the answer
0,15 moles of NaOH-------in------------1000ml
x moles of NaOH------------in--------100ml
x = 0,015 moles of NaOH
final volume = 150ml
0,015 moles of NaOH---in-------150ml
x moles of NaOH--------------in-----1000ml
x = 0,1 moles of NaOH
answer: 0,1mol/dm³ (molarity)
Answer : The correct option is B (clay, slit, sand).
Explanation :
Soil particles are of three types : Sand, Slit and clay. Most of the soils particles are made up of a combination of sand, slit and clay.
Particle size range of the sand = 2.00 -0.05 mm
Particle size range of the slit = 0.05 -0.002 mm
Particle size range of the sand = less than 0.002 mm
Sand is the largest soil particle, clay is the smallest soil particle and slit particle is present in between the sand & clay particle.
Therefore, the order from smaller to larger sediment particles is
Clay > Slit > Sand
Answer:
El volumen final del sistema es 1.2L
Explanation:
La ley de Charles establece que el incremento de la temperatura de un gas produce un incremento en el volumen directamente proporcional cuando la presión permanece constante. La ecuación es:
V₁/T₁ = V₂/T₂
<em>Donde V es volumen y T temperatura absoluta de un gas en 1, el estado inicial y 2, su estado final.</em>
<em />
Reemplazando:
V₁ = 1.3L
T₁ = 50°C + 273.15K = 323.15K
V₂ = Incógnita
T₂ = 300K
1.3L/323.15K = V₂/300K
1.2L = V₂
<h3>El volumen final del sistema es 1.2L</h3>
