Answer:
A double bond between carbon atoms
Explanation:
The suffix -ene is used for alkenes, which tells you that the molecule has a carbon-carbon double bond.
Answer:
Explanation:
Nitric Acid (HN03)
Zn(OH)2 + 2HNO3 ==> Zn(NO3)2 + 2HOH
The answer is false. I'm taking this class currently.
Answer:
Freezing point: <u>32 ºF (0ºC)</u>
Melting point: <u>32 ºF (0ºC)</u>
Boiling point: <u>203°F (95°C)</u>
Explanation:
At the boiling point, <u>the vapor pressure of a liquid equals the external pressure</u>. The normal melting point and boiling point of water at 1 atm are 0°C and
100°C, respectively. Decreasing the pressure under 1 atm (what happens when we are at high altitudes) will lower the boiling point since the external pressure will be lower, and it will become equal with the vapor pressure at a lower temperature.
However, the melting point and freezing point will stay unaffected since they don't depend on air-pressure; so at 0 or 5000 meters they will still be 0°C (remember that, <u>since water is a pure substance, the freezing and melting points will be the same</u>).
