Answer:
Carbon nanotubes have a very high melting point, as each carbon atom is joined to three other carbon atoms by strong covalent bonds. This also leaves each carbon atom with a spare electron, which forms a sea of delocalised electrons within the tube, meaning nanotubes can conduct electricity.
Explanation:
<span>So we need 0.276 moles of HCl to react. Your concentration is given in moles/liter so 0.276/1.58 = 0.174 liters needed or 174 milliliters</span>
A homogeneous mixture is a system that has properties that is uniform all through out the mixture. From the choices given above, I believe the correct answer is option D. Apple juice is an example of a homogeneous mixture. Hope this answers the question.
Answer:
physical change
Explanation:
there is no change in the water's chemical formula
Answer:
See explanation and image attached
Explanation:
The addition of excess hydrogen to alkyne in the presence of a platinum catalyst leads to complete hydrogenation of the alkyne as shown in the image attached.
Therefore, an alkane is obtained as the major organic product when excess hydrogen reacts with an alkyne in the presence of a platinum catalyst.
