Answer:

"Ecosystem is the major ecological unit. It has both structure and functions. The structure is related to species diversity. The more complex is the structure the greater is the diversity of the species in the ecosystem. The functions of ecosystem are related to the flow of energy and cycling of materials through structural components of the ecosystem."

Which pair of atoms has the most polar bond? (1) H−Br (2) H−Cl (3) I−Br (4) I−Cl

S_A_V [24]

For the question given above, option 2 which is H-Cl pair of atoms has the most polar bond among the four of them.

The larger the value of the electronegativity, the greater the atom’s strength to attract a bonding pair of electrons. Hydrogen has an electronegativity of 2.1, and chlorine has an electronegativity of 3.0. The electron pair that is bonding HCl together shifts toward the chlorine atom because it has a larger electronegativity value.

When lithium nitride, Li3N(s) , is treated with water, H2O(l) , ammonia, NH3(g) , is produced. Predict the formula of the gas pr

Ronch [10]

Answer: The gas produced when sodium phosphide reacts with water is phosphine.

Explanation:

When sodium phosphide reacts with water molecule, it leads to the production of flammable, poisonous gas known as phosphine along with the production of sodium hydroxide.

The chemical reaction for the reaction of sodium phosphide with water follows the equation:

$Na_3P(aq.)+3H_2O(l)\rightarrow PH_3(g)+3NaOH(aq.)$

By Stoichiometry of the reaction:

1 mole of sodium phosphide reacts with 3 moles of water to produce 1 mole of phosphine gas and 3 moles of sodium hydroxide.

Hence, the gas produced when sodium phosphide reacts with water is phosphine.
