Box 1

10g

Explanation:

Box 1, Mass of A = 10g

Box 2, Mass of B = 5g

Box 3, = 1A + 1B

Unknown:

Mass of B that would combine with mass of 20g of A

Solution:

   Mass ratio of A to B:

   \frac{mass of A}{mass of B} = mass ratio

           \frac{10}{5} = mass ratio

        The mass ratio of A to B = 2: 1

Now, number of B that will combine with 20g of A;

       

           \frac{mass of A}{mass of B} = mass ratio

               \frac{20}{mass of B} = \frac{2}{1}

                     Mass of B = 10g

10g of B would combine with 20g of A

A compound accepts electrons from another substance to form a covalent bond. Which term best describes this compound’s behavior?
Cloud [144]

A compound accepts electrons from another substance to form a covalent bond. The compound acts as a Lewis base.

<h3>What are the most common acid-base theories?</h3>
  • Arrhenius: acids release H⁺ and bases release OH⁻.
  • Bronsted-Lowry: acids donate H⁺ and bases accept H⁺.
  • Lewis: acids accept electrons and bases donate electrons.

A compound accepts electrons from another substance to form a covalent bond. Which term best describes this compound’s behavior?

  • Lewis acid. YES.
  • Arrhenius base. NO, because OH⁻ is not involved.
  • Bronsted-Lowry acid. NO, because H⁺ is not involved.
  • Bronsted-Lowry base. NO, because H⁺ is not involved.
