Answer:
Bromine
Explanation:
Br2 is an oxidizing agent, Na is a reducing agent.
Answer:
The answer is 2, 12 g of LiCl in 1 L of solution
Explanation:
We calculate the weight of 1 mol of LiCl:
Weight 1 mol LiCl= Weight Li + Weight Cl =6, 94 g + 35, 45 g= 42,39 g/mol
In a 0.05M solution it means that we have 0.05 moles of compound (in this case, LiCl) in 1 liter of solution:
1 mol---------42, 39 g LiCl
0,05mol-----x=(0,05molx 42, 39 g LiCl)/ 1 mol =2, 1195 g LiCl

Electron affinity is determined by the amount of energy released/spent for the atom to add an electron for neutral atoms in gas state.
Lower periodic table means a bigger radius atom. In this case, the distance between the electron to the nucleus is further too, so the affinity is expected to become lower.
In this question, the K and Cs are located in the first column of the periodic table, but Cs located lower. So, the Cs that located lower in periodic table should have a lower affinity.
Answer:
energy
Explanation:
The amount of energy carried by a wave is related to the amplitude in waves.
