Answer: 1.35x 10²³ molecules FeCl3
Explanation: First find the number of moles for FeCl3 using its molar mass which is equal to 162.2 g FeCl3
Convert moles of FeCl3 to molecules by using the Avogadro's number.
<span>The answer is "A tetrahedral molecule has 4 regions of high electron density around the central atom. These molecules have central atoms with 0 lone pairs and 4 atoms bonded to them." Based on the octet rule, the atom must have 8 electrons to become stable. As a result, the molecule will not have lone pairs.</span>
They react to form salt ZnCl + hydrogen gas
Answer:
Corresponds to a covalent compound.
Explanation:
Both Boron and Fluorine are nonmetals, forming a covalent bond, the result of which is the boron trifluoride compound (BF3). This is a highly toxic gas.
It is synthesized by the reaction between hydrogen fluoride and boron oxide:
B2O3 + 6 HF → 2 BF3 + 3 H2O
Nitrogen and oxygen are the most prevalent in the atmosphere.
