Some PROPERTIES of cathode rays:

• They travel linearly
• They have a NEGATIVE electric charge
• They have particle property
• Magnets can deflect them
• Charge/mass ratio of the rays is constant
• They travel from the cathode to the anode

Answer:

ELECTRON affinity increases upward for the groups and from left to right across PERIODS of a periodic table because the electrons added to energy levels become CLOSER to the nucleus, THUS a stronger attraction between the nucleus and its electrons.

SUBSTANCE which offers very high RESISTANCE to current flow it is called an insulator.

Some examples are wood, GLASS, PURE water etc.

Answer:

The elements in GROUP one of the periodic table (with the exception of hydrogen - see below) are known as the alkali metals because they form alkaline solutions when they REACT with water. ...

Reactivity Series in chemistry is an experimental, structural and logical progression of series of metals in order of reactivity from highest to LOWEST. Metals react differently with DIFFERENT substances. It GIVES a descriptive detail on metal reactions with the extraction of metals from ores and with ACIDS and WATER.

<STRONG>Answer:

RbOH > KOH > Mg(OH)2 > AL(OH)3

Explanation:

Generally basicity of oxides / hydroxides decreases from left to right along a period. In the the 3rd period, we see that Na20 is a strong base, MGO is basic and Al203 is amphoteric. So it can be said that hydroxides of G-1 are more basic than hydroxides of G-2.

Again if we MOVE from top to bottom along G-1, radius of cation increases, ionisation enthalpy decreases ( less energy is required to lose electron).

As a result solubility and basicity increases down the group.

Reverse osmosis (RO) is a WATER purification process that uses a partially permeable membrane to separate ions, unwanted molecules and larger PARTICLES from drinking water. ... APPLYING an external pressure to reverse the natural flow of PURE solvent, thus, is reverse osmosis.

Water purification is the process of REMOVING undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes

ANSWER:

Answer

Correct option is

B

On stirring, temperature INCREASES

C

Stirring increases the rate of interaction

Stirring, or agitation helps to disperse the particles of SUGAR throughout the water, which is another way of increasing the surface AREA of the sugar and accelerating the time it takes to dissolve. The stirring motion also increases kinetic energy, which increases the temperature of the solution – and that's the next way to make sugar dissolve more quickly. An increase in the kinetic energy of the constituent particle increases the rate of interaction as well as the temperature of the solution.

Hence, option (B) & (C) are correct.

Answer:

A metallic SOLID conducts ELECTRICITY in solid FORM but an ionic solid is a non-conductor in solid form and conducts electricity only on dissolution in water. In the metals the electrons are loosely held by their respective atoms and thus are FREE to CONDUCT electriciy.

➡️ A small magnetic field is created around the conductor with the direction of this magnetic field with regards to its “North” and “South” poles being determined by the direction of the current flowing through the conductor.

Magnetism plays an important role in Electrical and Electronic Engineering because without it components such as relays, solenoids, inductors, chokes, COILS, loudspeakers, motors, generators, transformers, and electricity meters etc, would not WORK if magnetism did not exist.

Then every coil of wire uses the effect of electromagnetism when an electrical current flows through it. But before we can look at Magnetism and especially Electromagnetism in more detail we NEED to remember BACK to our physics classes of how magnets and magnetism WORKS.
