Answer:tetrahedral
Explanation:
According to Valence Shell Electron Pair Repulsion Theory (VSEPR). The number of electron pairs on the valence shell of the central atom in a molecule influences the shape of that molecule. Four electron pairs around the central atom of a molecule leads to a tetrahedral geometry as predicted by VSEPR.
Answer:
Synthesis.
Explanation:
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
For example:
Mg + Cl₂ → MgCl₂
when magnesium combine with chlorine it form magnesium chloride.
Magnesium is alkaline earth metal and present in group two. Magnesium has two valance electrons. Magnesium atom loses its two electron to complete the octet. Chlorine is halogen element and have seven valance electrons. Chlorine needed one electron to complete the octet. When it combine with magnesium atom it accept the two electrons from magnesium atom that's why two chlorine atoms are combine with one magnesium atom to make the compound neutral.
Four significant figures would be B. Because 0's before the decimal are not important, but 0's after the decimal are.
Answer:
A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds.
Good luck !
