the chloride of a metal M contains 47.25% of metal 1.0 gram of metal would be displaced from a compound by 0.88 gram of another
GenaCL600 [577]

Answer:

The equivalent weight of M is approximately 31.8 g

The equivalent weight of N is approximately 27.98 g

Explanation:

The given parameters are;

The percentage of the the metal M in in the chloride = 47.25%

Where by the chemical formula for the metal chloride is MClₓ, we have;

47.25% of the mass of MClₓ = Mass of M = W

Therefore, we have;

\dfrac{0.4725}{W} = \dfrac{1}{W + 35.5 \cdot x}

0.4725 × (W +  35.5·x) = W

0.4725·W + 0.4725×35.5×x = W

W - 0.4725·W  = 16.77·x

0.5275·W = 16.77·x

W/x = 16.77/0.5275 = 31.799 = The equivalent weight of M

The equivalent weight of M = 31.799 ≈ 31.8 g

Given that 1 gram of M is displaced by 0.88 gram of N, then the equivalent weight of N that will displace 31.799 = 0.88 × 31.799 ≈ 27.98 g

The equivalent weight of N = 27.98 g.

Which of the following is true regarding the law of conservation of mass
Luda [366]
These are the answer options of this question and the comments about their validity:

<span>A) It dictates that the number of molecules on each side of a chemical equation must be the same.

False: the number of molecules can change. Take this simple reaction for example:

2H2(g) +  O2 -> 2H2O

You start with 3 molecules, 2 molecules of H2 and 1 molecule of O2, and end with 2 molecules of water. Then the number of molecules of each side is different.



B) It dictates that the number of atoms of each element must be the same on both sides of a chemical equation.

TRUE: in a chemical reaction the atoms remain being the same at start and at the end of the process. Given that each atom has a characteristic mass, their conservation implies the law of conservation mass.


C) It states that the mass of the reactants must remain constant in order for a chemical reaction to proceed.

FALSE. The mass of the reactants changes during a chemical reaction, while they transform into the products.

D) It does not apply to chemical reactions.

FALSE: It is an important law used in the calculus related with chemical reactions.

The last column of the periodic table contains the noble gases elements that do not easily form chemical bonds. Why don’t these
ozzi

Answer:

its is because the chemicals are very diffraction from each other so which makes it difficult to form a chemical bond.

Why is acetyl chloride hydrolyzed faster than benzoyl chloride?
klemol [59]
Because of the presence of an aromatic ring in benzoyl chloride. Aromatic rings have delocalized pi electrons that imparts unusual stability to the compound. Moreover, it makes it less polar compared to an Acetyl group.
