Oxygen and Hydrogen would most likely form a covalent bond that is polar, or a polar covalent bond. Due to the electronegativity difference between the 2 elements, unequal sharing of the valence electrons will occur, electrons being in closer proximity to Oxygen and farther away from Hydrogen. Resulting in the characteristic partial positive and negative charges to appear for the respective elements.
Answer:
its letter b
Explanation:
it represents the spectrum of stars
Answer:
Empirical Formula:
The empirical formula of a compound is the simplest whole-number ratio of the numbers of the different atoms that compose the molecule of the compound. The empirical formula looks like a molecular formula.
C

The mass of hydrogen in the compound: {eq}m_H = 5.1 \ \rm...
Theoretical
yield is the amount supposedly produced by the reaction if it was complete. The
balanced chemical reaction is:<span>
</span>
<span> C2H6 + Cl2 = C2H5Cl + HCl</span>
<span>
We use the amounts given for the reactants as
the starting point of the calculations to determine the limiting reactant. We do as follows:
150 g C2H6 ( 1 mol / 30.08 g
) = 4.987 mol
205 g Cl2 ( 1 mol / 70.9 g ) = 2.891 mol
Therefore, the limiting reactant would be Cl2 since it would be consumed completely first in the reaction.
We use this for the theoretical yield.
<span>2.891 mol Cl2 ( 1 mol C2H5Cl / 1 mol Cl2 ) = </span>2.891 mol C2H5Cl (THEORETICAL YIELD)
172 g ( 1 mol / 64.52 g ) = 2.666 mol C2H5Cl (
ACTUAL YIELD)
Percent yield = 2.666 / 2.891 x 100 = 92.21%</span>
The reactants and products must be both compounds.
Ex. AB+CD --> AD+BC
