The earth’s plates sliding against each other and moving under each other causes earthquakes. When plates move apart, magma comes up, thus forming a volcano.
Answer:
Balanced equation is: 2Na (s) + Cl₂(g) → 2NaCl (s)
Number of moles of needed Cl₂ → 0.217 moles
Mass of needed Cl₂ → 15.4 g
Explanation:
We determine the reaction
2Na (s) + Cl₂(g) → 2NaCl (s)
We convert the mass of solid Na to moles
10 g. 1 mol/23 g = 0.435 moles
Ratio is 2:1. 2 moles of Na react with 1 mol of chlorine
Then, 0.435 moles of Na may react with (0.435 . 1)/2 = 0.217 moles of Cl₂
Number of moles of needed Cl₂ → 0.217 moles
We convert the moles to mass → 0.217 mol . 70.9 g/1mol = 15.4 g
Acid palmitic acid has higher melting point, because it has two more methylene groups.
Acid palmitic acid has higher melting point, because it has two more methylene groups.
Giving it a greater surface area and therefore more intermolecular van der waals interact than the myristic acid.
stearic arid
linoleic acid (two double bond)
Stearic acid has higher Melting point, because it does not have any Carbon-Carbon double bonds, whereas linoleic acid has two cis double bonds which prevent the molecules from packing closely together.
Oleic Acid and Linoleic acid.
-one double bond (cis)
Acid palmitic acid has higher melting point, because it has two more methylene groups.
