<u>Answer: </u>The correct answer is Option A.
<u>Explanation:</u>
The molecule given in the question is HCl which forms a polar covalent bond.
A polar bond is defined as the bond present between two elements with different electronegativity value. The element which has higher electronegativity value, attracts the shared pair of electrons towards itself and forms a dipole. A polar molecule is dissolved more in a polar substance than in non-polar substance.
In the given compound, the electronegativity of chlorine is more than hydrogen and attracts the shared pair of electron more towards itself and hence is a polar molecule.
A non-polar bond is defined as the bond which is formed between the elements having same electronegativity value. No dipole is created in these type of bonds. Here, the electrons are shared equally.
From the above information, the correct answer is Option A.
Answer:
A
Explanation:
Because you need to multiply the length value by 1000
A. Identify the properties as either a physical or chemical property. (first 3 are chemical, last is physical)
Answer:Chemical properties such as its ability to form chemical bonds
Explanation:
The group to which an element belong is known by the number of electrons on its outermost shell. Since chemical reactions often involve valence electrons of an atom, the number of outermost shell electrons give us an idea of the chemical properties, reactivity and readiness of the element to form chemical bonds. The number of electrons in the outermost shell is the most succinct description of the chemical disposition of any atom.
