Increase in greenhouse gas emission
Explanation:
Global average temperature of the earth is increasing due to a surge in the amount of greenhouse gases being emitted.
The major greenhouse gas is carbon dioxide.
This gas is produced by a wide range of industrial processes and combustion of fuels in automobiles.
Anomalous concentration of this gas in the atmosphere leads to an increase in earth's temperature.
These gases interacts with long wave radiation produced by the earth and prevents them from escaping. In turn, they warm the earth and keep it at fairly uniform temperature.
When these gases are too much in concentration they lead to an anomalous increase in temperature.

Answer:
C) cation, loses, anion, gains
Explanation:
Lithium is a metal from Group 1, so it has 1 valence electron. Thus, it loses 1 electron to complete its octet and form the cation Li⁺.
Oxygen is a nonmetal from Group 16, so it has 6 valence electrons. Thus, it gains 2 electrons to complete its octet and form the anion O²⁻.
In the reaction between Li and O, there is a transfer of electrons making an ionic bond. In the bond, lithium would be a cation because it loses an electron, and oxygen would be an anion because it gains 2 electrons.
Answer:
Identify the "given" information and what the problem is asking you to "find."
Given : Cl2O7
Find: % Composition (% Cl and %O)
List other known quantities.
Mass of Cl in 1 mol Cl2O7 , 2 Cl : 2 x 35.45 g = 70.90 g
Mass of O in 1 mol Cl2O7 , 7 O: 7 x 16.00 g = 112.00 g
Molar mass of Cl2O7 = 182.90 g/mol
