Do your structures resemble the following? H-C=C-H

Chemistry

Damm [24]3 years ago
3 0

Answer:

For the HCCH Lewis structure you'll need to form a triple bond between the two carbon atoms. Hydrogen atoms only need two electrons for a full outer shell. There are a total of 10 valence electrons for the HCCH Lewis structure.

Which of the following statements is an example of an ionic bond? a Li-F b H-Cl c C-C D o-h
IceJOKER [234]

Answer:

Li-F

Explanation:

Hydroxide  is a negative ion, which can form ionic bonds with metals, but the bond in hydrogen and oxygen in hydroxide (OH-) is not ionic. It is covalent in nature.

C-C is clearly a covalent bond.

Li-F is an ionic bond.

Bond between H and Cl in H-Cl is covalent in nature. Because of the size difference hydrogen can not act as a cation. So it rather dissociates.

63.15 mL of calcium hydroxide is required to titrate 18.9 mL of a 0.200 M H3PO4 solution. What is the molarity of the basic solu
Kruka [31]

Answer:

0.0898M is the molarity of the basic solution

Explanation:

The reaction of calcium hydroxide, Ca(OH)₂ with H₃PO₄ is:

3 Ca(OH)₂ + 2 H₃PO₄ → 6H₂O + Ca₃(PO₄)₂

To solve this question we must find the moles of H3PO4 that react. With the moles and the rection we can find the moles of Ca(OH)2. Using its volume we can find its molarity:

<em>Moles H3PO4:</em>

0.0189L * (0.200mol / L) = 0.00378 moles H3PO4

<em>Moles Ca(OH)2:</em>

0.00378 moles H3PO4 * (3mol Ca(OH)2 / 2mol H3PO4) = 0.00567 moles Ca(OH)2

<em>Molarity:</em>

0.00567 moles Ca(OH)2 / 0.06315L =

<h3>0.0898M is the molarity of the basic solution</h3>
