Increase of rainfall will accelerate chemical weathering. Especially if the runoff is slightly acidic.
Answer:

Explanation:
Hello!
In this case, since the heat of vaporization is related with the energy required by a substance to undergo the phase transition from liquid to gas, we can compute such amount of energy as shown below:

In such a way, since the enthalpy of vaporization is given as well as the mass, we compute the energy as shown below:

Best regards!
Answer:
Explanation:
The electronic configuration of a lithium atom is 2.1 and that of a fluorine atom is 2.7
an atom of lithium donates an electron to an atom of fluorine to form an ionic compound. The transfer of the electron gives the lithium ion a net charge of +1, and the fluorine ion a net charge of -1.
Answer: THREE<span> different isomers can be derived from ethylene if two hydrogen atoms are replaced by a fl uorine atom and a chlorine atom.
Explanation: When two Hydrogen atoms in ethylene (
C</span>
₂H₄) are replaced with Fluorine and Chlorine atom then the new molecular formula is
C₂H₂FCl.
Compounds having same Molecular formula but different structural formula are called as Isomers.
First Isomer of C₂H₂FCl is
1-chloro-1-fluoroethene, in which F and Cl at geminal position (attached to same Carbon atom).
Other two Isomers are
Geometrical Isomers of
1-chloro-2-fluoroethene, in which F and Cl at different carbon atom and having different position is space. The one in which both F and Cl at opposite side forms
(<em>
trans</em>
)-1-chloro-2-fluoroethene and the one in which both are in same side is called as
(<em>
cis</em>
)-1-chloro-2-fluoroethene.
Answer: Except for gamma decay or internal conversion from a nuclear excited state, the decay is a nuclear transmutation resulting in a daughter containing a different number of protons or neutrons (or both). When the number of protons changes, an atom of a different chemical element is created.
