Chemistry
1 answer:
posledela3 years ago
6 0

The weight/weight percent(%w/w) of NaCl in  solution : 33.03%

<h3>Further explanation</h3>

Given

Mole fraction of NaCl : 0.132

Required

The weight/weight percent of NaCl

Solution

1 mol solution : 0.132 mol NaCl + 0.868 mol H₂O

mass NaCl :

\tt 0.132\times 58.44 g/mol=7.714~g

mass H₂O :

\tt 0.868\times 18.016~g/mol=15.64~g

Total mass = 7.714 + 15.64 = 23.354 g

\tt \%NaCl=\dfrac{7.714}{23.354}\times 100\%=33.03\%

Which statements below describe the law of conservation of mass? *
topjm [15]

Answer:

Mass cannot be created or destroyed

Explanation:

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

These models show the electron structures of two different nonmetal elements.
Soloha48 [4]

Answer: Option (D) is the correct answer.

Explanation:

Valence shell is the shell present on the outermost core of an atom and electrons present in the valence shell are known as valence electrons.

If an atom has completely filled valence shell then it means the atom is not reactive in nature because it is already stable.

But when an atom has less than eight electrons in its valence shell then it means to attain stability the atom will readily attract electrons towards itself.

As the given element 1 has 8 electrons in its valence shell. Hence, it is not reactive in nature but element 2 has 6 valence electrons. So, in order to attain stability element 2 will readily attract 2 electrons from a donor atom.

Thus, we can conclude that element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.
