SANA MAKATULONG PO ♥️♥️
The answer would be A) cells!!
Answer:
sp3 - 1,2,13,16,18,19
sp2- 3,4,5,6,7,8,9,10,11,12,14,15,17
sp- 0
Explanation:
Hybridization is the idea that atomic orbitals fuse to form newly hybridized orbitals, which in turn, influences molecular geometry and bonding properties (Chemlibretexts).
Carbon atoms that are singly bonded are sp3 hybridized, carbon atoms that are doubly bonded are sp2 hybridized while carbon atoms that are triply bonded are sp hybridized.
Sp3 hybridized atoms have a tetrahedral geometry, sp2 hybridized atoms have a trigonal planar geometry while an sp hybridized atom has a linear geometry.
The hybridization state of each atom in the compound has been shown in the answer section.
Percentage error is the relative error your measured value is from the true or accepted value. The formula for percentage error is written below:
Percentage error = |True Value - Measured Value|/True Value * 100
Percentage error = |0.75 g/mL - 0.78 g/mL|/0.75 g/mL * 100
Percentage error = 4%
0.16 M of Cu
<u>Explanation:</u>
Molarity = moles/volume
Here, we have to find the moles from the molar mass of CuSO₄. 5H₂O is 249. 71 g/ mol
Now we can find the moles as,
1 g CuSO₄. 5H₂O × ( 1 mol CuSO₄. 5H₂O / 249. 71 g of CuSO₄. 5H₂O) × 1mol of Cu / 1 mol CuSO₄. 5H₂O
= 0.0040 mol Cu
Now we have to find the concentration in terms of molarity as,
molarity = moles/ volume = 0.0040 moles/ 0.025 L = 0.16 M of Cu.
