Answer:

a) number of neutrons

Explanation:

A sodium ion is formed when an electron is removed from a sodium atom. This means that the atom's number of electrons changes, but the number of neutrons remains unchanged.

However, as the number of electrons changes, the electric charge and the electronic structure change, which means that a sodium atom and a sodium ion do not have the same number of electrons, nor do they have the same electric charge or electronic structure.

Therefore, option a) is the correct option.

Convert 2.39 x 1022 molecules of water into moles of water

torisob [31]

Answer:

$0.0397\ \text{mol}$

Explanation:

Number of molecules of water = $2.39\times 10^{22}$

$N_A$ = Avogadro's number = $6.022\times 10^{23}\ \text{mol}^{-1}$

Number of moles is given by

$\dfrac{2.39\times 10^{22}}{6.022\times 10^{23}}$

$=0.0397\ \text{mol}$

The number of moles of water is $0.0397\ \text{mol}$ .

Water is a great solvent. For example, it causes ionic compounds like sodium chloride (table salt) to dissociate. One of these r

Ira Lisetskai [31]

Answer:

A polar molecule has both a partial positive and a partial negative. Since NaCl (sodium chloride) is made out of Na+ and Cl- ions, the positive and negative parts of the water will pull on these ions individually since positive attracts negative and negative attracts positive. This magnetic force causes the Na+ and the Cl- ions to be pulled apart.

Which of the following expressions is the correct equilibrium-constant expression for the equilibrium between dinitrogen tetroxi

nekit [7.7K]

Answer:

D. [NO₂]²/[N₂O₄]

Explanation:

The equilibrium constant expression for a reaction is products over reactants. Since NO₂ has a coefficient of 2, it will become an exponent.

So, it would be:

[NO₂]²/[N₂O₄]
