For each statement check if it describes ionic, polar covalent, nonpolar covalent, or metallic bonds: Ionic Polar Covalent Nonpolar Covalent Metallic A transfer of electrons between two atoms Positive nuclei dispersed in a sea of mobile electrons Metals and nonmetals bonding One atom loses, and another atom gains electrons Two atoms share electrons equally Metals bonding only Electronegativity differences under 0.4 A bond resulting from electrostatic charges between opposite charged particles Two atoms share electrons unequally Nonmetals bonding only Electronegativity differences over 0.4 and between 2 Non metals

Explanation:

Ionic bond: it is formed through electrostatic attraction between a cation(metal) and an anion(non metal).In other words, an ionic bond is formed when a metal loses an electron and a non metal gains it. If the electronegativity difference is more than 1.7,the bond will exhibit an ionic characteristic.

Covalent bond: this type of bonding exists between non metals. It involves sharing of electron between two non metals.

Metallic bond: is formed between positively charged atoms, where free electrons are shared among lattice of cations.It is mostly formed between metal atoms.

Polar covalent bond:  it is a type of covalent bond formed due to unequal sharing of electrons between two atoms. This is mainly due to the fact that one element will have a stronger attraction for electrons than the other. If the electronegativety difference is between 0.4 and 1.7, the bond will be a polar covalent.

Non polar covalent: it is a type of covalent bond formed due to equal sharing of electrons between two atoms.Thus the electronegativity difference would be less than 0.4

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
