<span>In the given chemical equation, 4 moles of nh3 gas react with 5 moles of oxygen to form 6moles of water vapours (h2o). Hence each mole of nh3 contributes to production of 1.5 moles of water vapours.
therefore, the rate of formation of h2o is 1.5*0.5 ms-1, i.e 0.75 moles/sec</span>

Answer:
In classical theories of gravitation, the changes in a gravitational field propagate. A change in the distribution of energy and momentum of matter results in subsequent alteration, at a distance, of the gravitational field which it produces.

Explanation:
What makes something an Ionic Bond:
- Ionic bonds are generally between two oppositely charged ions. Usually salts are formed.
- A metal and nonmetal are also generally considered to be ionic.
- Electronegativity also plays a role in a difference of electronegativity of elements being greater than 2.0.
For 1) Na has a charge of 1+ and Cl has a charge of 1-. They both come together to form table salt. Their electronegativity is also larger than 2.0. Also Na is a metal and Cl ion is a nonmetal.
For 2) C and O are both nonmetals and are covalent bonds
For 3) Water is a polar covalent molecule because there is a electronegativity difference between H and O, but not great. H and O are also nonmetals.
For 4) While Fe is a metal and O is a nonmetal, their electronegativity difference is not greater than 2.0. This makes it polar covalent.
For 5) Mg is a metal and S is a nonmetal. They have a large electronegativity difference. Also Mg has a charge of 2+ while S has a charge of 2-.
