Explanation:
What is the reducing agent in the reaction 2N a + 2H 2O → 2N aOH + H 2? Sodium metal. You're dealing with a redox reaction in which sodium metal, Na, is being oxidized to sodium cations, Na+, and hydrogen is being reduced to hydrogen gas, H2.
The cell wall is the outer most covering of the cell. The cell wall
covers the cell membrane. The cell membrane is also known as the plasma
membrane or plasma
lemma. There is no other name for the cell wall. The cell membrane is
present in almost all types of cells. The cell wall is present in
bacteria, fungi, algae and plant cell.
It is absent in an animal cell and protozoa. The cell membrane is a
biological membrane, which is semi- permeable. It allows the passage of
certain substances through them.
Answer: True.
Explanation.
The group 7A is actually named group 17.
That group is the halogens: F, Cl, Br, I, At, and Ts (Ts is one of the last elements discovered).
Those elements have 7 valence electrons (notice that it is the same number as the second digit in 17).
The atoms with 7 valence electrons will "easily" gain one electron to get the configuration of the next noble gas (8 valence electrons). That is why these elements gain electrons to form ions.
When atoms gain electrons form anions (negative ions). For example: F(-), Cl(-), Br(-), I(-).
