Answer:

Estos elementos se denominan metales de transición, metales pesados, elementos del bloque D, etc.

Explanation:

Aquí, en esta pregunta, queremos saber la razón por la cual hay un espacio de 10 elementos entre el calcio, que es un elemento del grupo dos, y el galio, que es un elemento del grupo 3.

Al observar la tabla periódica, la tabla periódica moderna, notamos un bloque de elementos entre los elementos del grupo 2 y los elementos del grupo 3 en la tabla periódica.

Entonces, ¿por qué se colocan estos elementos entre ambos grupos? Se colocan aquí porque no pertenecen en su totalidad al grupo 2, ni tampoco al grupo 3.

Estos elementos presentan una especie de estados de oxidación variables que son responsables de una amplia variedad de propiedades comunes entre ellos.

olga_2 [115]

Answer : The molar mass of protein is, 1.38\times 10^4g/mol

Explanation :

Formula used :

\pi =CRT\\\\\pi=\frac{w\times 1000}{M\times V}RT

where,

\pi = osmotic pressure  = 0.138 atm

C = concentration

R = solution constant  = 0.0821 L.atm/mol.K

T = temperature  = 28^oC=273+28=301K

w = mass of protein subunit = 0.155 g

M = molar mass of protein subunit = ?

V = volume of solution  = 2.00 mL

Now put all the given values in the above formula, we get:

\pi=\frac{w\times 1000}{M\times V}RT

0.138atm=\frac{0.155g\times 1000}{M\times 2.00ml}\times (0.0821L.atm/mole.K)\times (301K)

M=13878.17g/mol=1.38\times 10^4g/mol

Therefore, the molar mass of protein is, 1.38\times 10^4g/mol

To prepare 250mL of calcium chloride solution with a molar concentration of 1.20mol/L, what mass of calcium chloride would be re
e-lub [12.9K]

Answer:

33.30 grams of CaCl2 will be required

Explanation:

Given,

Volume of solution, V= 250 ml

Molarity of solution, M= 1.20 mol/L

Molecular mass of CaCL2, S= 40+(35.5 X 2)= 111

We know,

Required mass, W= SVM/1000

Now,

W = (111 X 250 X 1.20)/1000

    = 33300/1000

    = 33.30

Therefore, 33.30 grams of Calcium Chloride will be required.
