Which of the following is not a part of the ideas john dalton proposed in his model

1 answer:

4 0

The following which is not a part of Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.

<h3>What is Dalton atomic theory?</h3>

Dalton has proposed his theory in three parts and each part stated that

The first portion of his theory asserts that all stuff is made up of indivisible atoms.

According to the second section of the theory, all atoms of a given element have the same mass and characteristics.

Compounds, according to the third section, are combinations of two or more different types of atoms.

Dalton has given three laws

Law of conservation of mass
Law of definite proportion
Law of multiple proportion

Thus, the following which is not a part of Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.

Answer:

The mass of 10 cm³of a 0.4 g/dm³ solution of sodium carbonate is 0.004 grams

Explanation:

The question is with regards to density calculations

The density of the given sodium carbonate solution, ρ = 0.4 g/dm³

The volume of the given solution of sodium carbonate, V = 10 cm³ = 0.01 dm³

$Density \ of \ an \ object, \rho = \dfrac{The \ mass \ of \ the \ object, \ m }{\ The \ volume \ of \ the \ object, \ V }$

$\rho = \dfrac{m}{V}$

Therefore, we have;

$The \ Density \ of \ the \ sodium \ carbonate, \ \rho = 0.4 \ g/dm^3 = \dfrac{m }{ 0.01 \ dm^3 }$

The mass, "m", of the sodium carbonate in = ρ×V = 0.4 g/dm³ × 0.01 dm³ = 0.004 g

The mass of 10 cm³ (10 cm³ = 0.01 dm³) of a 0.4 g/dm³ solution of sodium carbonate, m = 0.004 g.

Solution A is 0.44 M and reacts with 0.11 M of solution B. Assume that the value of x is 0, the value of y is 1, and r is 1.07 ×

xz_007 [3.2K]

Answer:

K, the rate constant = 9.73 × 10^(-1)/s

Explanation:

r = K × [A]^x × [B]^y

r = Rate = 1.07 × 10^(-1)/s

K = Rate constant

A and B = Concentration in mol/dm^-3

A = 0.44M

B = 0.11M

x = Order of reaction with respect to A = 0

y = Order of reaction with respect to B = 1

Solving, we get

r/([A]^x × [B]^y) = K

K = 1.07 × 10^(-1)/s/(0.44^0 × 0.11^1)= 0.9727

K = 0.9727
