Answer:

Follow safety measures and safety rules to avoid any accident.

Explanation:

1. Follow all safety measures is needed from adults when they conducting any experiment at home in order to prevent any damage occurs due to that experiment.

2. Safety rules should always be followed when conducting an experiment at any place such as at home, class room and laboratory etc in order to avoid any accident.

3. Some chemicals are very dangerous because they are flammable and catch fire when allow it to the heat source. Some chemicals also cause suffocation by absorbing all the oxygen from the environment and as a result death occurs.

4. Science is a systematic study of physical objects through observation and experiments. Science is a knowledge gain from experiments.

Explanation:cell division occurs to produce new cells from preexisting ones. the new cells are called daughter cells.the old cells are called parent cells.cell division may be mitosis or meiosis. Mitosis occurs in a somatic cell and produce four daughter cell. Meiosis occurs in sex cells and produce two daughter cells. Cell division usually involves Prophase, metaphase, anaphase and telophase.

Cell division occurs to ensure the continous existence of life.

Write a balanced half-reaction for the oxidation of aqueous hydrazine N2H4 to gaseous nitrogen N2 in basic aqueous solution
Zigmanuir [339]

Answer:

N2H2(aq) + 2OH^-(aq) ----------> N2(g) + 2H2O(l) + 2e

Explanation:

Hydrazine is mostly used in thermal engineering as an anticorrosive agent. Hydrazine can be oxidized in aqueous solution as shown in the equation above. Oxidation has to do with loss of electrons and increase in oxidation number.

The oxidation number of nitrogen in the equation increased from -1 in hydrazine on the lefthand side of the reaction equation to zero in nitrogen on the right hand side of the reaction equation. Two electrons were lost in the process as shown.
