Answer:
Molecular Evidence.
Answer:
C.
Explanation:
Iron is most likely to form a precipitation reaction.
Evaporation is a physical phenomenon, as with the action of sunlight, the atoms that make up water (H2O) will stick to a greater state of agitation, causing their separation and subsequent evaporation. In more pressure, more energy would be required (heat, sunlight) to cause the separation. There is no change in the properties of the element, and the process is reversible.

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.
The correct answer is 6.15g of CO2 will be produced.
The approach to answer this question is to use the molar mass to find the number of moles of oxygen consumed. Then use the chemical equation to determine the number of moles of CO2 that would be produced (half that of oxygen). Then use the molar mass of CO2 to calculate the mass.
Mmass O2 = 32g/mol
Mmass CO2 = 44.01g/mol
mass O2 consumed = 8.94g
mass CO2 produced = ?
moles O2 = mass / molar mass = 8.94 / 32 = 0.279
moles CO2 = half that of O2 = 0.1397
mass CO2 produced = moles CO2 x molar mass = 0.1397 x 44.01 = 6.15 g
