Cerrena [4.2K]4 years ago
3 0

Answer:

2 HgO    →      2 Hg + O₂

 (2 x 216.59 g) → gives → (2 x 200.59 g)

  433.18 g   → gives → 401.18 g

    8.74 g     → gives → ? g

by cross multiplication:

Theoretical yield = (401.18 x 8.74) / 433.18 = 8.094 g

% yield = (actual yield / theoretical yield) * 100

            = (6.42 / 8.09) * 100 = 79.3 %

As the pendulum moves from point 2 to point 3, what happens to its mechanical energy?potential energy is converted to kinetic en
ahrayia [7]

Answer: Potential energy is converted to kinetic energy and back again.

Explanation:At points 1 and 3, the pendulum stops moving, and its mechanical energy is purely potential. At point 2, the pendulum is moving the fastest, and its mechanical energy is purely kinetic. Therefore, as the pendulum moves from point 1 to point 3, its potential energy is first converted to kinetic energy, then back to potential.
