The correct answer is option d, that is, Zn + H₂SO₄ → ZnSO₄ + H₂
A single displacement reaction refers to a kind of chemical reaction in which one element substitutes another element in a chemical reaction. The more reactive element will substitute the less reactive element. This is illustrated with the help of reactivity series, as the metal that is present above in the series will substitute the metal that is present below in the series readily. From the given equations, Zn + H₂SO₄ → ZnSO₄ + H₂ is a kind of single displacement reaction.
The correct answer for the question that is being presented above is this one: "C. planetesimals ® heavier elements ® inner planets ® protoplanets" The list of the stages of development of the inner planets is this <span>C. planetesimals ® heavier elements ® inner planets ® protoplanets</span>
Answer:
SeF4 is a polar molecule
Explanation:
SeF4 is a polar molecule because a polar molecule is any molecule that have lone pairs of electrons in the central atom or have atoms that are electronegative and the electrons between that are covalently bonded are not evenly distributed.
The electronegative atoms of flourine in SeF4 are not evenly distributed and kind pairs of electrons are on the central atom.
