Answer:

The pressure and volume of a gas are inversely related

Explanation:

If we look at all the options stated; we will notice that all the statements are correct according to the kinetic theory of gases; except the statement "The pressure and volume of a gas are inversely related".

Recall that the inverse relationship between pressure and volume of a gas is captured by Boyle's law and not the kinetic molecular theory. Hence this statement is not part of the kinetic molecular theory.

I need help ASAP please<br> Calculating pH<br> See chart below
laila [671]

Answer:

12, basic, 9, basic

Explanation:

pH = -log[H+]

Using the data in the table, you can calculate the pH:

-log[1e-12] = 12

-log[1e-9] = 9

To find out whether it is acidic, basic, or neutral, use a pH scale. Anything less than 7 is acidic, anything over is basic. Knowing this, both will be basic.

What is the concentration of chloride ion when 16.8ml of a 0.554 M solution of barium chloride is combined with 16.8ml of a 0.59
ozzi

Answer:

The concentration of chloride ion is 2.887 M.

Explanation:

Here we have a combination BaCl₂  and AlCl₃

1 mole BaCl₂ can produce 2 moles chloride ions as follows;

BaCl₂ → Ba²⁺ + 2Cl⁻

Therefore;

0.554  mole BaCl₂ can produce 2×0.554  moles chloride ions;

1 mole AlCl₃ can produce 3 moles chloride ions as follows;

AlCl₃ → Al³⁺ + 3Cl⁻

Therefore;

0.593 mole AlCl₃ can produce 3×0.593 moles chloride ions

Total concentration of chloride ions = 2×0.554 + 3×0.593 = 2.887 moles of Cl⁻ in 2×16.8 ml solution

The concentration of Cl⁻ is 2.887 M

water is considered as a compound of hydrogen and oxygen and not a mixture of hydrogen and oxygen and comment on it
HACTEHA [7]
Wat is considered a compound of hydrogen and oxygen and not a mixture because hydrogen and oxygen have gone through a chemical process to form the compound h2O. A mixture can generally be easily separated whereas a compound must undergo another chemical process to separate its elements. Therefore to separate oxygen and hydrogen from water a chemical process is necessary.
