A scientific law is an explanation to a well observed phenomenon of the world which is found true every time tested and universal proven fact, but the reason behind the phenomenon and its existence.

To explain the scientific law there will be various explanation that are called scientific theory, however these theories can not be proved.

Thus, the correct answer is - scientific law.

Consider the reversible reaction A ( g ) − ⇀ ↽ − B ( g ) Which K values would indicate that there is more B than A at equilibriu

oksano4ka [1.4K]

Answer:

5000 and $8\times 10^{7}$ indicate that there is more B than A at equilibrium

Explanation:

For the given reaction: $K=\frac{[B]}{[A]}$

where [B] and [A] represents equilibrium concentration B and A respectively. K represents equilibrium constant

More B than A at equilibrium means, [B] > [A]

So, $K=\frac{[B]}{[A]}>1$

As, both 5000 and $8\times 10^{7}$ are greater than 1 therefore these two K values indicate that there is more B than A at equilibrium

What type of ions do metals naturally form? Negative ions, by gaining electrons to fill the valence shell Negative ions, by losi

Mila [183]

Answer: Option (d) is the correct answer.

Explanation:

Metals are the species which contain more number of electrons.

When a specie loses electrons then it acquires a positive charge. Whereas when an atom gains electrons then it acquires a negative charge.

Thus, as metals have more number of electrons, therefore, in order to gain stability metals readily lose electrons.

Hence, metals naturally form positive ions, by losing electrons to empty the valence shell.
