What causes ionic bonding between two atoms?

Marrrta [24]

Answer:

Ionic bonding happens when an atom of an element gives one or more of its electrons to the other element's atom..it usually takes place between metal and non metal atoms...like in NaCl, Na gives its valence electron to chlorine and completes its own octet. Chlorine accepts the electron and completes its own octet too...but now both the atoms have an opposing charge and hence they attract each other to form an IONIC bond.

Ionic bonds are the strongest of the bonds...here complete transfer of electrons takes place unlike covalent bonds.

Determine the number of grams of C4H10 that are required to completely react to produce 8.70 mol of CO2 according to the followi

Nitella [24]

Answer:

126.4 g of $C_{4}H_{10}$ are required

Explanation:

Balanced reaction: $2C_{4}H_{10}+13O_{2}\rightarrow 8CO_{2}+10H_{2}O$

According to balanced reaction-

8 moles of $CO_{2}$ are produced from 2 moles of $C_{4}H_{10}$

So, 8.70 moles of $CO_{2}$ are produced from $(\frac{2}{8}\times 8.70)$ moles of $C_{4}H_{10}$ or 2.175 moles of $C_{4}H_{10}$

Molar mass of $C_{4}H_{10}$ = 58.12 g/mol

So, mass of $C_{4}H_{10}$ required = $(2.175\times 58.12)g$ = 126.4 g

Hence 126.4 g of $C_{4}H_{10}$ are required
