please solve this...........​

Answer 1

zno and al2o3

Step-by-step explanation:

amphoteric oxides are those oxides that are both acidic and basic in nature..

For example: ZNO and AL2O3

Answer 2

1.The dark particles shown in the delivery tube are Zn granules which reacts with dil. H2SO4

solution present in the same tube. Soap solution depicted in the image is received in a vessel. The bubbles evolved are due to presence of hydrogen gas.

2.The electrical potential difference is defined as the amount of work done to carrying a unit charge from one point to another in an electric field. In other words, the potential difference is defined as the difference in the electric potential of the two charged bodies. Unit: The unit of potential difference is volt.

3.The properties of magnetic field lines can be summarized by these rules: ... Magnetic field lines can never cross, meaning that the field is unique at any point in space. Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.

4.While the primary function of the platelet is thought to be hemostasis, thrombosis, and wound healing through a complex activation process leading to integrin activation and formation of a “core” and “shell” at the site of injury, other physiological roles for the platelet exist including immunity and communication

Next Roman letter :-

3.Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide. Al2O3 is an example of an amphoteric oxide. Amphoteric oxides also include Lead (II) oxide, and zinc (II) oxide, among many others.

4. (a) Combustion

Next Roman Letter :-

2.Sodium carbonate (washing soda) is used in glass, soap and paper industries. ... ii) Uses of baking Soda : 1)Used for making baking powder which is a mixture of baking soda and tartaric acid. It is also used in soda - acid fire extinguishers.
