Answer:

  • Option d. i<u><em>t is higher than the energy of both reactants and products</em></u>

Explanation:

<em>Activated complex</em>, also known as transition state, is the intermediate structure formed in the course of a chemical reaction.

The activated complex is very unstable and of short life: it is at the peak of the potential chemical diagram, and can transform either into the reactants (backward) or the products (forward).

The activation energy of the reaction is the energy needed to reach the activated complex, then both reactants and products are lower in potential chemical energy than the activated complex, which is what explains why the activated complex can transform into one or another, reactants or products.

G determine the concentration of an hbr solution if a 45.00 ml aliquot of the solution yields 0.6485 g agbr when added to a solu
Sunny_sXe [5.5K]

The molecular weight of silver bromide (AgBr) is 187.77 g/mole. The presence of the ions in solution can be shown as- AgBr (insoluble) ⇄Ag^{+} + Br^{-1}.

45.00 mL of the aliquot contains 0.6485 g of AgBr. Thus 1000 mL of the aliquot contains \frac{0.6485}{45}×1000 = 14.411 gm-mole. Thus the solubility product K_{sp}of AgBr = [Ag^{+}]×Br^{-}.

Or, 5.0×10^{-13} = S^{2} (the given value of solubility product of AgBr is 5.0×10^{-13} and the charge of the both ions are same).

Thus S = (5.00×10^{-13})^{1/2} = 7.071×10^{-7} g/mL.

Thus the concentration of Br^{-1} or HBr is 7.071×10^{-7} g/mL.

Which statement about silver Ag metal is least reliable
Anna007 [38]
<span>The choices for this question can be found elsewhere and as follows:

Silver is a transition metal with electrons in the d shell.
Silver atoms have 47 protons in their nuclei.
Silver atoms commonly form ions with a +1 charge.

I think the correct answer is the last option. The least reliable information would be that s</span>ilver atoms commonly form ions with a +1 charge.

The image shows two opposite forces acting on a rolling cart, what can we say is true about the effect on the forces on the cart
bonufazy [111]

Question options:

1. It cannot be determined without knowing which man is stronger.

2. The forces are unbalanced, and net force on the cart moves it to the left.

3. It cannot be determined because one man is taller than the other.

4. The forces are unbalanced, and net force on the cart moves it to the right.

Answer:

<em>2.The forces are unbalanced, and net force on the cart moves it to the left.</em>

Explanation:

In the image, two opposite forces acting on a rolling cart. The person on the right side exerting more force (50N) toward the left than the person on the left side (10N). The more the force applying on the object, it will drag on the followed direction.

It is because the person on the right side exerting force  (50N) toward the left, rolling cart will moves to the left.
