Answer:
C. it's relative distance to earth is closer than the other stars
Answer:
The answer is given below
Explanation:
When electronegativity difference arises between the bonded atoms, then a molecule is polar.
When electros are shared equally between the bonded atoms or when the polar bonds in a bigger molecule cancels out each other, then a a molucule is non polar.
(a) 50% isopropanol/H2O,--- 2 (second least polar)
(b) 25% isopropanol/H2O,----- 3 (third least polar)
(c) pure water----- is 4 (most polar)
(d) 70% isopropanol/H2O. 1 (least polar)
Answer:
No matter how many times you cut it, its chemical properties won't change and it'll still be paper.
Explanation:
Answer:
4. mutualism
5. commensalism
Explanation:
4. mutualism (they benefit off each other)
5. commensalism (the whale is unaffected)
Volatile organic compounds can be detected by hydrogeologists in the field or labs because of the odor of the vapors emitted from the groundwater and/or soil samples.
<h3>What are volatile substances?</h3>
Volatile substances are substances which can easily vaporize or change to gaseous state.
Volatile substances can either be solids or liquids but are mostly liquids.
Example of volatile substances include ether, petrol, chocolate.
The presence of volatile substances can be detected by the gases they release which may have characteristic odors.
Therefore, volatile organic compounds can be detected by hydrogeologists in the field or labs because of the odor of the vapors emitted from the groundwater and/or soil samples.
