PLEASE HELPPP 100 POINTS!!
1. At 1 atm and 298 k, pentane is a liquid whereas propane is a gas. Explain.
2. At 1 atm and 298 k, methanol is a liquid whereas propane is a gas. Explain.
3. Indicate the hybridization of the carbon atom in each of the following:
i) Methanol
ii) Methanoic (formic) acid
4. Draw the complete lewis electron-dot diagram for a molecule of propanoic acid, HC3H5O2.
5. Explain the following observations about the two carbon-oxygen bonds in the methanoate (formate) anion, HCO2-.
i) The two carbon-oxygen bonds in the methanoate (formate) anion, HCO2-, have the same length.
ii)The length of the carbon-oxygen bonds in the methanoate (formate) anion, HCO2-, is the intermediate between the length of the carbon-oxygen bond in methanol and the length of the carbon-oxygen bond in methanal.

1) pentane is of higher Molecular mass than propane hence heavier member

2) due to intermolecular hydrogen bonding methanol is liquid having lower molecular weight

3) I) in methanol C = sp3

ii) in methanoic acid C= sp2

5)I) i) The two carbon-oxygen bonds in the methanoate anion, HCO2-, have the same length due to resonance stabilization of the C-O bond

Explanation:

See attachment for question 4

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
