Chemical CHANGE

Change from one substance to the other involves the interaction of substances among themselves, leading to the formation of something new out of the substances in interaction. These changes are KNOWN as the chemical changes.

For EXAMPLE, the formation of curd from milk involves the interaction of TWO substances which results into chemical reaction between the lactic acid bacteria and the casein.

I don't UNDERSTAND it

The (1/2)TH POWER of 2, written in mathematics as √2 or 21⁄2, is the positive algebraic number that, when multiplied by itself, equals the number 2. Technically, it is called the principal square root of 2, to distinguish it from the negative number with the same property.

Geometrically the square root of 2 is the length of a diagonal across a square with sides of one unit of length; this follows the Pythagorean theorem. It was probably the first number known to be IRRATIONAL.[CITATION needed]

As a good rational approximation for the square root of two, with a reasonably small denominato sometimes used.

The OEIS CONSISTS of the digits in the decimal expansion of the square root of 2, here truncated to 65 decimal places:

DFTP scheme provides DUTY free and preferential treatment to about 98% of India's TARIFF LINES, up from the initial 85% when the scheme commenced in 2008. To make the scheme more ATTRACTIVE to LDCs, and to African LDCs in particular, the Government amended the exclusion and Margin of Preference lists in 2014.

ANSWER:

firstly we TEST three tubes with the HELP of litmus paper

• in case of distilled WATER , red litmus paper doesn't shows purple colour , because it is neutral
• in case of acidic solution , red litmus paper it will remain red
• in case of basic solution it will show blue colour ...

Answer:

Industrial uses. Chemical inertness makes the material especially valuable for industrial applications, including corrosion-resistant coatings and as a base for various adhesives. Neoprene is also used in sealing gaskets, especially in relation to electricity, due to its heat and static resistance.

Electrical and electronic uses. Neoprene’s FIRE and static resistance explain why it is commonly used in power transformers, light bulbs, wires, and other electrical applications as an insulator. It is also used as a protector for electronics such as laptops for the same reason, as well as its cushioning abilities.

Safety equipment uses. The material’s ability to continue to function in a wide RANGE of temperatures while providing thermal resistance and remaining flexible makes neoprene fabric an ideal fit for gloves and other protective wear. Neoprene’s oil, chemical, and water resistance provide ADDITIONAL protection.

Marine uses. As a result of neoprene’s water and thermal resistance properties, it is also used in wet-suits and diving-suits—nitrogen is added to increase insulation which increases overall buoyancy, so the suits must be weighted to prevent them from floating or pulling the diver back toward the surface. However, because neoprene contains air-pockets and is subject to compression as pressure increases, the efficiency of a neoprene wet-suit decreases as water depth and distance from the surface increases.

Automotive uses. Neoprene can be used to make automotive parts, as it is abrasion, tear, solvent, oil, and weather-resistant, as well as heat and fireproof. It can be found in window and door seals, hose covers, belts, vibration mounts, and shock absorber seals.

Medical uses. Thanks to neoprene’s flexibility, wearability, and ability to keep its shape over time, it is used to make supports and braces, including wrist, knee, and elbow supports.

Packaging uses. Because neoprene is a soft rubber by nature, it is also a useful source of padding and reinforcement for certain fragile applications.

Construction uses. Thanks to its weather, temperature, and compression resistance, neoprene is used in WASHERS, bridge bearing PADS, elevator astragals, and other construction materials.

Explanation:

Answer:

The 'temperature of a substance'remains constant during its melting and boiling point because the change in any state of matter as n solid to liquid or the liquid to a gas INVOLVES CROSSING the 'latentheat of FUSION' which CAUSES a change in the intermolecular spacing of the MOLECULES in thesubstance.

Answer:

d) HCl

Explanation:

the reason is that Chlorine being LARGER in size and more electronegative than Hydrogen tends to shift the LONE PAIR towards its thereby MAKING hydrogen atom slightly positive charged and Chlorine negatively charged.

Solution: M₁v₁ + M₂v₂ + M₃v₃ = Mv

→ 2(1 M × 200 ML) + 3 M × 300 mL + 2 M × 100 mL = M × 1000 L

→ 400 + 900 + 200 = 1000M

→ 1500 = 1000 M

→ 1.5 = M (OPTION 2)

Focus

♦ We did 2(1 M × 200 mL) in case of H₂SO₄ because H₂SO₄ has basicity of 2 while HCl has basicity of 1.
