I think the answer is B or the 2nd one, hope this helped c:
I would actualy label it or put a little diagram below to show what part it is
Answer:
a mole of calcium is 6.02 ×10²³, therefore 2.9 ×10²⁴ will be ~4.82moles,
And since a mole of calcium is 40.1g
4.82 moles will be 4.82 × 40.1
that's =193.28g
Answer:
sp atomic orbital
Explanation:
CO has a triple bond, which is composed of one sigma bond and two pi bonds. Pi bonds are formed using one p orbital from each atom, so the carbon atom must have two unhybridized p orbitals in order to form two pi bonds. The other s and p orbitals that it has are hybridized together to form two sp orbitals. One of the sp orbitals is used in the sigma bond and the other holds the lone pair.
