Why pluto is removed from planet?​

Pluto was ruled not a planet anymore because it is a "dwarf  planet"

Apparently, the International Astronomical Union's (IAU) definition of a planet includes that a planet should be part of a body that would orbit the sun.  

According to the IAU, there are three criteria's that contribute to a planet being called a planet.

1. It is within orbit around the Sun.

2. It has a sufficient mass to assume a nearly round shape

and 3. It has "cleared the neighborhood" around it's orbit.

Pluto only so happens to meet 2 of these requirements, not including the third option.

Answer:

In august 2006 the international astronomical union (IAU) downgraded the status of Pluto to that of "Dwarf planet." this means that from now on only the rocky worlds of the inner solar system and the gas giants of the outer system will be designated.

Answer:

97.0%m/m es la concentración de la solución

Explanation:

El porcentaje masa/masa (%m/m) se define como 100 veces el radio entre la masa de soluto (300g de HCl) y la masa de la solución. Para hallar la masa de la solución debemos hallar la masa del agua (Solvente) haciendo uso de la ecuación del volumen de un cono. Con el volumen del cono podemos hallar la masa del agua haciendo uso de la densidad, así:

<em>Volumen:</em>

Volumen Cono = π*r²*h / 3

Donde r es el radio = 0.300m

h la altura = 5m

Volumen = π*(5m)²*0.300m / 3

7.85m³

<em>Masa Agua:</em>

7.85m³ * (1.2g / m³) = 9.42g Agua

<em>Masa solución:</em>

300g HCl + 9.42g Agua = 309.42g Solución

<em>%m/m:</em>

300g HCl  / 309.42g * 100 =

A student takes a sample of KOH solution and dilutes it with 100.00 mL of water. The student determines that the diluted solutio
Firlakuza [10]

Answer:

2.2mL

Explanation:

First, let us analyse what was given from the question:

C1 = 2.09M

V1 =?

C2 = 0.046M

V2 =100mL

Using dilution formula (C1V1 = C2V2), we can calculate the volume of the original solution as follows:

C1V1 = C2V2

2.09 x V1 = 0.046 x 100

Divide both side by the coefficient of V1 ie 2.09, we have:

V1 = (0.046 x 100) / 2.09

V1 = 2.2mL
