Answer:
In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

The answer would be: <span>D. Kb for HS–
</span>
Kb is the dissociation constant of an acid/base molecule. The word b in Kb is base, which means the formula should have an OH- ion inside it. Ka would be the opposite of Kb where the formula has H+ ion.
In this question, the formula is: [H2S][OH-]/ [HS-]
Since there are OH- ion. Since H2S is acid and HS- is base, I think it should be <span>Kb for HS–

Considering the reaction:
3NO₂ + H₂O → 2HNO₃ + NO
To produce 3.56 moles of nitric acid, we require:
3.56 x 3/2 moles of NO₂
Moles of NO₂ = 5.34 moles of NO₂
Answer:
Explanation:
Hello,
In this case, we use the ideal gas equation to compute the volume as shown below:
Nonetheless we are given mass, for that reason we must compute the moles of gaseous fluorine (molar mass: 38 g/mol) as shown below:
Thus, we compute the volume with the proper ideal gas constant, R:
Best regards.
Electronegativity is determined by factors like the nuclear charge
