Answer:
The eluting strength of a solvent is primarily related to how strongly it adsorbs onto the adsorbent and because typical adsorbents are highly polar; thus, eluting strength increases with solvent polarity.
Explanation:
The polarity of a solvent makes it more suitable for elution in a polar adsorbent. Hence the choice of solvents should be in order of increasing rather than decreasing polarity. polarity must increase and not decrease
Answer:
0.137 M NH3
Explanation:
First divide the mass of NH3 by the molar mass of NH3, and then divide by the volume to get molarity.
0.583 g / 17.031 g/mol = 0.0342 mol NH3
0.0342 mol NH3 / 0.250 L = 0.137 M NH3
northern america is the correct answer i’m pretty sure
Answer:
becomes runoff and finds its way back to the ocean
Explanation:
Precipitation refers to rainfall that reaches the earth.
Most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean.
When the rain falls on earth, some evaporates, some enters into the ground while some runs off into rivers and streams. Almost all of the rain water flows into the oceans or other bodies of water.
Hence, most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean
