Answer:

pH = 5.7

Explanation:

<em>Which is the pH of the solution?</em>

The pH is a measurement widely used in chemistry in quality assurance of products and another analysis. Is defined as the -log [H3O+]. That means, the pH of the solution that is [H3O+] = 2x10-6 M is:

pH = -log [H3O+]

pH = -log [2x10-6 M]

<h3>pH = 5.7</h3>

a compound has an empirical formula of CH2 what is the molecular formula if it's molar mass is 252.5 grams/mol
Goryan [66]

Empirical formula is the simplest ratio of components making up the compound. the molecular formula is the actual ratio of components making up the compound.

the empirical formula is CH₂. We can find the mass of CH₂ one empirical unit and have to then find the number of empirical units in the molecular formula.

Mass of one empirical unit - CH₂ - 12 g/mol x 1 + 1 g/mol x 2 = 12 = 14 g

Molar mass of the compound is - 252 .5 g/mol

number of empirical units = molar mass / mass of empirical unit

                                           = \frac{252.5 g/mol}{14 g}

                                           = 18 units

Therefore molecular formula is - 18 times the empirical formula

molecular formula  - CH₂ x 18 = C₁₈H₃₆                                            

molecular formula is C₁₈H₃₆

CH4(g) + H2O(g) CO(g) + 3H2(g)
boyakko [2]
Presuming the arrow is between H20 and CO

On the left there are 2 gas moles.
On the right there are 4 gas moles.

The equilibrium will shift to the side with the most no. He gas moles when pressure is decreased.

Therefore the answer is A, since 4>2.
