Answer:
See explanation
Explanation:
A dipole refers to a bond in which its two ends have opposite charges. A dipole results from a large difference in electronegativity between two atoms in a bond.
For instance, consider the bond between hydrogen and chlorine in HCl. The electronegativity of hydrogen is 2.2 while that of chlorine is 3.16. The significant electronegativity difference between the two atoms leads to a charge separation.
A partial positive charge appears on the atom that is less electronegative (hydrogen) while a negative charge appears on the more electronegative atom (chlorine).
This charge separation occurs because the shared electrons of the bond are more closely attracted to chlorine making it partially negative compared to hydrogen. A dipole moment now exists in the H-Cl bond hence the molecule is said to have a dipole.
Answer:
a) 0.15
Explanation:
A concentração de sacarose é 0,15 g / l no etanol. O Brasil está produzindo etanol em grandes quantidades que é usado como combustível em veículos e indústrias. Este etanol é produzido a partir da cultura da cana-de-açúcar e o Brasil é o segundo maior produtor mundial com cerca de 34,45 bilhões de litros em 2019. Os Estados Unidos da América e o Brasil produzem cerca de 84% do etanol mundial.
Answer:
12 amu or 12 g.
Explanation:
One mole of 12C = one 12c atom. The mass of one carbon-12 atom is 12.000 amu.
Answer: 510 L of oxygen gas were consumed.
Explanation:
According to ideal gas equation:
P = pressure of gas = 750 torr = 0.99 atm (760 torr= 1atm)
V = Volume of gas = 620 L
n = number of moles of carbon dioxide = ?
R = gas constant =
T =temperature =
According to stoichiometry:
8 moles of are produced by = 13 moles of oxygen
Thus 9.08 moles of are produced by = moles of oxygen
P = pressure of gas = 540 torr = 0.71 atm (760 torr= 1atm)
V = Volume of gas = ?
n = number of moles of oxygen = 14.8
R = gas constant =
T =temperature =
Thus 510 L of oxygen gas were consumed.
