Answer:
They are both colorless, odorless, and tasteless. They have the same number of valence electrons too. And unbalanced electrons in their valence shell.
Explanation:
<em>Octopus and squids breathe</em> <em>like </em><em>fishes </em><em>they </em><em>breathe </em><em>from </em><em>gills </em>
<em>so </em><em>even </em><em>octopus</em><em> and</em><em> squids</em><em> </em><em>breathe </em><em>through </em><em>gills </em><em>too.</em>

<span>To produce a molar conversion, you need to know the molar mass of each molecule.
I presume you mean there are 192 grams of O2. The molecular weight of oxygen is 16 g/mol. Therefore, O2 is 32 g/mole.
If there are 192 grams of O2, then:
192 grams x (1 mole/32g) = 6 moles of O2.
To react each mole of oxygen, you need 2 moles of hydrogen (H2). You can see this in the equation 2H2 + O2 --> 2 H20.
To react 6 moles of O2, you need 12 moles of H2.
Now that we have the total moles of hydrogen needed, we now use the molar mass of H2 (2 grams/mole)
12 moles H2 x (2 grams/1 mol H2) = 24 grams of H2.</span>
Answer:
Carbonate
Explanation:
Carbonate is a combination of a carbon atom and two oxygen atoms for form a compound.
Answer:
a. H₂S(aq) + H₂O(l) ⇄ HS⁻(aq) + H₃O⁺(aq)
b. NH₄⁺(aq) + H₂O(l) ⇄ NH₃(aq) + H₃O⁺(aq)
Explanation:
According to Bronsted-Lowry acid-base theory,
- An acid is a substance that donates a H⁺.
- A base is a substance that accepts a H⁺.
a. When dissolved in water, H₂S behaves as an acid according to the following equation.
H₂S(aq) + H₂O(l) ⇄ HS⁻(aq) + H₃O⁺(aq)
b. When dissolved in water, NH₄⁺ behaves as an acid according to the following equation.
NH₄⁺(aq) + H₂O(l) ⇄ NH₃(aq) + H₃O⁺(aq)
