Answer:
K = 137.55 atm/M.
Explanation:
- The relationship between gas pressure and the concentration of dissolved gas is given by Henry’s law:
<em>P = (K)(C)</em>
where P is the partial pressure of the gaseous solute above the solution (P = 1.0 atm).
k is a constant (Henry’s constant).
C is the concentration of the dissolved gas (C = 7.27 x 10⁻³ M).
∴ K = P/C = (1.0 atm)/(7.27 x 10⁻³ M) = 137.55 atm/M.
Answer:
The correct answer to your question is letter A
Explanation:
a. [ Ca: ] This structure is correct because Calcium has 2 valence electrons and in this structure we can see them as points to the right side of the symbol.
b. [ Ca ]2+ This option is not correct, in Lewis dot representation, electrons are points and this structure do not show them.
c. No right choice. This option is wrong because letter A is correct.
Answer:
2.18 mol Ar.
Explanation:
Hello there!
In this case, according to the definition of mole as the amount of particles of a given substance, it is possible to introduce the Avogadro's number to assert that 1 mole of any element contains 6.022x10²³ atoms; thus, the moles of Ar in the given amount of atoms turns out to be:
Best regards!
Answer:
True
Explanation:
They have four distinct stages: egg, larva (caterpillar), pupa (chrysalis), and adult. For monarch butterflies, it takes about a month to grow from an egg to an adult.
The life cycle of a frog consists of three stages: egg, larva, and adult.
