To find the number of neutrons, take the atomic mass minus the atomic number

the mass is given in the question as 23. the atomic number you can find in the periodic table for sodium, which is 11.

neutrons= 23 - 11= 12 neutrons

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 =

<h3>97.0%m/m es la concentración de la solución</h3>

According to the law of conservation of mass, the amount of BARIUM present of the reactants is the same as the amount present in the products (the precipitate). 

(11.21 g BaSO4) / (233.4 g/mol BaSO4) = 0.0480 mol BaSO4 and original barium salt 

(10.0 g) / (0.0480 mol) = 208.3 g/mol 

So it must have been BaCl2, because the molar mass of Barium is 137 which leave 71 grams left. Since Barium is a +2 charge, it means the atom next to it must be twice. Chlorine mass is 35, which twice is 71

1. Why does light have different effects on various materials?
Debora [2.8K]
Light basically evaporates pigments such as colored paper. Exposed pigment fading is kind of like getting colored paper wet. It will fade and bleed.
