It is a covalent bond. Whenever a compound uses such suffixes like mono, di, tri, tetra, and so on, it is a covalent compound- thus having covalent bonds.

Answer:

It's a covalent bond

Explanation:

The diference of electronegativity between the two atoms bonding can help you to decide if a bond is either covalent or ionic.

As shown in the figure, the oxygen atoms of the nitrate (left) will interact with the nitrogen atom of the thiamine(right).

The oxygen have an electronegativity of 3.5 (one of the most electronegative elements) and the nitrogen a 3.0

Being the difference: 3.5 - 3.0=0.5

Now, how this helps to decide the type of bond? For covalent bonds it's expected to have a electronegativity diffetence of < 1.5. On the other hand, for ionic bonds this value should be > 1.5

Lithium nitride reacts with water to produce ammonia and lithium hydroxide according to the equation, Li3N(s) + 3H2O (L) -->

Gemiola [76]

Answer:

0.480 grams

Explanation:

Li₃N(s) + 3D₂O (L) --------------------------> ND₃(g) + 3LiOD (aq)

1 : 3 : 1 : 3

Number of moles (n) = Mass in gram/ Molar Mass

Mass of ND₃ = 160 mg

= 0.16 g

Molar mass of ND₃= [14 + (3 x 2.014 )]

= 14 + 6.042

= 20.042 g/mol

Number of moles of ND₃ = 0.16/20.042

= 0.007983 moles

From the reaction equation, the mole ratio between Heavy water (D₂O ) and ND₃ is 3: 1.

This implies that the number of moles of Heavy water (D₂O ) required

= 3 x 0.007983 moles

= 0.023949 moles

Molar mass of Heavy water (D₂O )= [(2.014 x 2) + 16]

= 20.028 g/mol

Mass in grams of Heavy water (D₂O )= Number of moles x Molar mass

= 0.023949 x 20.028

= 0.4797 grams

≈ 0.480 grams
