Determine which pair of atoms has the greatest polarity.

2 answers:

5 0

According to the chart represented above, I have determined the pair of atoms which has the greatest polarit and I am pretty sure that it is the first option from the scale :A. Al-Si. I consider this to be correct due to their incredible difference difference in electronegativity.
Hope it helps!

Answer: Option (C) is the correct answer.

Explanation:

Atoms which have high difference in electronegativity will be more polar in nature.

This is because more electronegative atom will attract the electrons more towards itself. And, this causes development of a partial negative charge on the electronrgative and a partial positive charge will develop on the atom from which electrons have been withdrawn.

For example, N-H will be polar in nature because of the difference in electronegativity of N and H.

Whereas Al-Si, S-Cl, and C-N are all non-metals with not much difference in electronegativity.

Thus, we can conclude that N-H pair of atoms has the greatest polarity.

3Co2 (aq) 6NO3(aq) 6Na (aq) 2PO43–(aq) → Co3(PO4)2(s) 6Na (aq) 6NO3(aq) Identify the net ionic equation for this reaction.

Burka [1]

Answer : The net ionic equation will be,

$3Co^{2+}(aq)+2PO_4^{3-}(aq)\rightarrow Co_3(PO_4)_2(s)$

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

$3Co^{2+}(aq)+6NO_3^-(aq)+6Na^+(aq)+2PO_4^{3-}(aq)\rightarrow Co_3(PO_4)_2(s)+6Na^+(aq)+6NO_3^-(aq)$

In this equation, $NO_3^-(aq)\text{ and }Na^+(aq)$ are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

Thus, the net ionic equation will be,

$3Co^{2+}(aq)+2PO_4^{3-}(aq)\rightarrow Co_3(PO_4)_2(s)$

Both natural products and synthetic products come from natural resources. Explain why this statement is true.

xz_007 [3.2K]

Explanation:

All resources used in making all products can be traced to their natural origin. What differentiates a natural product from a synthetic one is the level of processing that goes into making synthetic products.

For example, a synthetic product such as plastic is actually derived from natural product.
Instead of using the sap of rubber plants for making this product, scientists engineered a way to produce plastics from petroleum products which are derived from crude oil.
Most synthetic products are merely products of alternate source of manufacturing which are well engineered.

Which statement best describes the pH of pure water?

Ray Of Light [21]

The pH of pure water is neutral because the concentration of hydronium ions equals that of hydroxide ions.

Answer: Option A

Explanation:

Water is one of the most important constituents of living being. It is said that there is no life without water. So that water need to neutral in nature to save life. Pure water is composed of hydronium $H^{+}$ and hydroxide $\left(O H^{-}\right)$ ions. It is known that hydronium ions are acidic in nature with concentration of $1 \times 10^{-7} \mathrm{M} / \mathrm{L}$ .

Similarly, the hydroxide ions which are basic in nature will be in same concentration as that of hydronium ions. So, as the concentration of basic and acidic elements are equal with the same strength of pH, the combination of these ions lead to formation of pure water with the pH being neutral.
