Answer:

The correct answer is B) Cl and Mg

Explanation:

An ionic bond is produced by the union of a cation and an anion. In this case, Mg would be the cation and Cl the anion. They will form the compound Magnesium Chloride (MgCl2):

Mg + Cl2 ----> MgCl2

Mg belongs to group 2 of the periodic table, that is, it has two valence electrons. In the case of Cl, it is in group 7 and has seven valence electrons (requires one electron to complete the octet).

Reil [10]

Answer:

1027.62 g

Explanation:

For $B_2H_6$ :-

Mass of $B_2H_6$ = 296.1 g

Molar mass of $B_2H_6$ = 27.66 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{296.1\ g}{27.66\ g/mol}$

$Moles\ of\ B_2H_6= 10.705\ mol$

From the balanced reaction:-

$B_2H_6(g) + 3 O2_{(l)}\rightarrow 2 HBO_2_{(g)}+ 2 H_2O_{(l)}$

1 mole of $B_2H_6$ react with 3 moles of oxygen

Thus,

10.705 mole of $B_2H_6$ react with 3*10.705 moles of oxygen

Moles of oxygen = 32.115 moles

Molar mass of oxygen gas = 31.998 g/mol

<u>Mass = Moles * Molar mass = 32.115 * 31.998 g = 1027.62 g</u>
