The best answer is "spatial" because a landscape is by definition, a wide open area. A paragraph using the other three methods would not be the best.
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.
The total pressure of the flask is sum of partial pressures of the gases present in a mixture of gas
This is Dalton's law of partial pressures .'
say we have a mixture of "n" gases with respective pressure : P1, P2 ...Pn
total pressure of the gases = P1 +P2 + P3 + ...Pn = Ptotal
So in the given problem the total pressure of flask will be = 0.72+1.65 = 2.37 atm
Answer: Heterogeneous Catalyst
Explanation: The word heterogeneous means "different phases" or insoluble in science.
