Answer:
In gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.
Explanation:
Answer:
step 2 then step 1 then step 3 then step 4
Explanation:
First boil it. Then identify the situation which is most conducive to boiling
.
While this, a liquid must overcome the attractive forces between molecules and the outside pressure pushing down on the liquid's surface.
The liquid will boil when there is weak intermolecular attraction and low atmospheric pressure.
Steps to be followed:
Pentane at high altitude
Hexane at high altitude
hexane at sea level
hexanol at sea level
Answer:
Image A
Explanation:
The hemisphere experiences summer when it is tilted towards the sun. Image a has the northern hemisphere tilted towards the sun.
Oxygen proton number is 8 so its 2.6 so it have 6 valence electron
The number of moles of O2 that are needed to react with 24 moles of C2H6 is 84 moles of O2
<u><em>Explanation</em></u>
Step 1: write the equation for reaction
= 2C2H6 +7O2 → 4CO2 + 6H2O
Step 2: use the mole ratio to determine the moles of O2
- that is the mole ratio of C2H6 : O2 is 2:7
- therefore the moles of O2= 24 x7/2= 84 moles of O2
