Hello there.
Question: <span>Plants remove which greenhouse gas from the atmosphere?
Answer: It is C. Carbon Dioxide. As you know, plants take in carbon dioxide and let out oxygen.
Hope This Helps You!
Good Luck Studying ^-^</span>
Answer:
Dispersion forces- Xe, CH4
Dipole-dipole forces-CHCl3
Hydrogen Bonding-HBr, NH3, CH3COOH
Explanation:
Gases and nonpolar molecules posses only dispersion forces. Polar covalent compounds posses dipole- dipole forces. When hydrogen is bonded to a highly electronegative atom, hydrogen bonding results. These account for the arrangement of answers above.
Answer:
The process of dissolving can be endothermic (temperature goes down) or exothermic (temperature goes up).
When water dissolves a substance, the water molecules attract and “bond” to the particles (molecules or ions) of the substance causing the particles to separate from each other.
The “bond” that a water molecule makes is not a covalent or ionic bond. It is a strong attraction caused by water’s polarity.
It takes energy to break the bonds between the molecules or ions of the solute.
Energy is released when water molecules bond to the solute molecules or ions.
If it takes more energy to separate the particles of the solute than is released when the water molecules bond to the particles, then the temperature goes down (endothermic).
If it takes less energy to separate the particles of the solute than is released when the water molecules bond to the particles, then the temperature goes up (exothermic).
Explanation:
Answer:
Since AlCl3 sublimes and NaCl does not sublime sublimation process will separate the two. Heat the mixture, aluminium chloride sublimes into vapour and forms the sublimate on the cooler parts of heating tube sodium chloride will remain at the bottom of the heating tube.
