Answer:

0.726 mol·L⁻¹

Step-by-step explanation:

c = moles/litres

=====

Moles = 29.8 × 1/342.30

Moles = 0.087 06 mol

=====

Litres = 120 × 1/1000

Litres = 0.120 L

=====

c = 0.087 06/0.120

c = 0.725 mol·L⁻¹

Which will NOT occur when a light tray ray interacts with a smooth pane of glass?
zhuklara [117]

Answer:

B) diffraction

Explanation:

A smooth pane of glass does not diffract light. A light passing through a smooth pane of glass may be absorbed, reflected or transmitted.

Diffraction only occurs with special types of glasses embedded with a diffraction grating and are called super prisms. Diffraction glasses use a a gradient lens which is able to  separate light into all the colors of the rainbow.

Recall that diffraction is the separation of white light into its component wavelengths.

In cellular chemical pathways, the product(s) of any particular reaction are often quickly consumed by the next reaction in the
mezya [45]

Answer:

Tend to keep the product concetration <u>low</u> and therefore drive the reaction <u>righward</u>

Explanation:

The fact the products of a reaction are quickly consumed by the next one would tend to keep the product concetration low and therefore drive the reaction righward (to the products).

This happens because the system will not achive equilibrium between the reactants and the product, and will keep producing it util the system achives equilibrium or the reactants dry out.

What is the pH of a solution with an [H+] = 4.73x10^-7 M
Mice21 [21]

Answer:

The answer to your question is pH = 6.3

Explanation:

Data

pH = ?

[H⁺] = 4.73 x 10⁻⁷ M

pH is the measure of the concentration of [H⁺]. pH measures the acidity of the solution. If the value of pH is between 0 and 6.9, the solution is an acid. If the pH is 7.0 the solution is neutral and if the pH is between 7.1 and 14, the solution is an alkali.

Formula

pH = -log[H⁺]

Substitution

pH = -log[4.73 x 10⁻⁷]

-Simplification

pH = - (-6.3)

-Result

pH = 6.3
