Answer:
AWWWWWWWWWWWWWWWW SOOO NICEEE
The Lewis structures for formate ion and carbon dioxide are shown in the attached pictures. As you can see, the formate ion consists of one C=O bond and one C-O bond, while carbon dioxide has two C=O bonds. Double bonds are weaker, hence, longer compared to single bonds. Therefore, the C-O bonds in the formate ion is shorter than those in carbon dioxide.
The relationship is matter and gas that go along with science
Answer:
0.767 g.
Explanation:
Molarity (M) is defined as the no. of moles of solute dissolved in a 1.0 L of the solution.
M = (no. of moles of K⁺)/(Volume of the solution (L).
<em>∵ no. of moles of K⁺ = (mass/molar mass) of K⁺.</em>
<em>∴ M = (mass/molar mass) of K⁺/(Volume of the solution (L).</em>
<em></em>
M = 0.0044 M.
Volume of the solution = 4459.0 mL = 4.459 L.
mass of K⁺ = ??? g.
molar mass of K⁺ = 39.01 g/mol.
∴ mass of K⁺ = (M)((molar mass of K⁺)(volume of the solution (L)) = (0.0044 M)(39.10 g/mol)(4.459 L) = 0.767 g.
