Answer: The answer has 7 significant figures
Explanation:
The addition of 190.5 and 42.1014 will give 232.6014. Counting the digits will give 7 significant figures.
What are the option for the questions???
is the orbital hybridization of a central atom that has one lone pair and bonds to three other atoms.
<h3>What is
orbital hybridization?</h3>
In the context of valence bond theory, orbital hybridization (or hybridisation) refers to the idea of combining atomic orbitals to create new hybrid orbitals (with energies, forms, etc., distinct from the component atomic orbitals) suited for the pairing of electrons to form chemical bonds.
For instance, the valence-shell s orbital joins with three valence-shell p orbitals to generate four equivalent sp3 mixes that are arranged in a tetrahedral configuration around the carbon atom to connect to four distinct atoms.
Hybrid orbitals are symmetrically arranged in space and are helpful in the explanation of molecular geometry and atomic bonding characteristics. Usually, atomic orbitals with similar energies are combined to form hybrid orbitals.

f it is solid iron, use the density to get the mass. D x V = mass
Use the mass to find the moles of Fe. Mass/atomic mass = moles
Moles x Avogadro's number will give you the particles, assuming that you mean atoms.
no. The metal would be the hottest
