Mama L [17]3 years ago
5 0

Answer:

B.

Explanation:

A scientific theory is a broad explanation that is widely accepted because it is supported by a great deal of evidence. Because it is so well supported, a scientific theory has a very good chance of being a correct explanation for events in nature. Because it is a broad explanation, it can explain many observations and pieces of evidence. In other words, it can help connect and make sense of many phenomena in the natural world.

Sulfur has two filled energy levels and six electrons on the third energy level. The corresponding electron configuration is A.
B is incorrect because there are no p orbitals at the first energy level, ie, no 1p orbitals. C is incorrect because the 4s1 electron would spontaneously drop into the 3p orbitals. D is incorrect because the 3d electrons would spontaneously drop into the 3p orbitals.

FinnZ [79.3K]

Answer: The correct answer is option B.

Explanation: Reactivity of elements is defined as the tendency to loose or gain electrons.

These reactions are a type of single displacement reactions. A single displacement reaction is a type of reaction in which an element displaces another element in a chemical reaction. These are studied with the help of reactivity series.

The element which lies above in the reactivity series can easily displace the element which lies below in the reactivity series.

Option A: This reaction will not yield a stable product because Zinc lies below Aluminium in the reactivity series.

AlBr_3+Zn\rightarrow \text{No reaction}

Option B: This reaction will yield a stable product because Sodium lies above Calcium in the reactivity series.

CaBr_2+2Na\rightarrow 2NaBr+Ca

Option C: This reaction will not yield a stable product because Hydrogen lies below Magnesium in the reactivity series.

MgBr_2+H_2\rightarrow \text{No reaction}

Option D: This reaction will not yield a stable product because Calcium lies below Barium in the reactivity series.

BaBr_2+Ca\rightarrow \text{No reaction}

Option E: This reaction will not yield a stable product because barium lies below Lithium in the reactivity series.

2LiBr+Ba\rightarrow \text{No reaction}
