Answer:
1.30 moles
Explanation:
As written, the molar mass of the fat is 770.5 g/mole. Add all the C, H, and O's (I get C48H98O6) and multiply by the molar mass of each. I obtain the 770.5 grams/mole figure, but would note that a more common fat is actually C3H5(O<u>H</u>(CH2)14(CH3))3 and not C3H5(O<u>O</u>(CH2)14(CH3))3.
Assuming C3H5(OO(CH2)14(CH3))3 is the correct structure, 1000g would mean 1000g/(770.5 g/mole) = 1.298 moles, or 1.30 moles to 2 sig figs.
Answer:
choice 3
Explanation:
Hydrogen bonding occurs when a H is bonded to a highly electronegative atom like F. Towards the upper right corner, most atoms have high electronegativity and small atomic radii, according to periodic trends.

Answer:
Option D and Option B
When comparing the two elements K and Ge , the more metallic element is_____K_____ based on periodic trends alone.
When comparing the two elements Sb and Pb , the more metallic element is_____Pb______ based on periodic
Explanation:
The metallic characteristic increases when we move down a column in a periodic table or when we move left in the row.
Potassium and Germanium are located on the same row, but germanium lies on the right side of potassium. Thus, potassium (K) is more metallic than Germanium (Ge)
While Lead (Pb) lies to left of Sb in the adjacent column and is also lies below Sb. Hence Pb is more metallic than Sb
B.. it is a combination reaction... A + B--> AB
