The International Day to Protect Education from Attack is an international observance established by the United Nations General Assembly on September 9 every year. It was established in response to the growing number of attacks on schools and educational institutions around the world. The day is an opportunity to raise awareness of the importance of protecting education from attacks and to call for action to prevent these attacks.

Useful strategies for teaching students with mental retardation include the following:

• Teach one concept or activity component at a time
• Teach one step at a time to help support memorisation and sequencing
• Teach students in small groups, or one-on-one if possible
• Always provide multiple opportunities to practice skills in a number of different settings
• Use physical and verbal prompting to guide correct responses, and provide specific verbal praise to reinforce these responses

Emission (n₂ = 5 to n₁ = 2) is called Balmer series and appears in visible region.

X is a primary, chiral alcohol.

• Autoxidation is any oxidation that occurs in presence of oxygen.
• The term is usually used to describe the degradation of organic compounds in air (as a source of oxygen).
• Autoxidation produces hydroperoxides and cyclic organic peroxides.

Oxidation Numbers in Oxygen Difluoride (OF₂) and Dioxygen Difluoride (O₂F₂)

Oxidation numbers are assigned to elements in compounds according to several rules. Here, we'll use the rule that states the oxidation number of fluorine (F) in a compound is always -1, and the rule that states the sum of oxidation numbers of all atoms in a compound is 0.

Oxidation Number in OF₂:

• In Oxygen Difluoride (OF₂), there are two fluorine atoms, each with an oxidation number of -1. So, the total oxidation number contributed by fluorine is -2.
• To mak e the total oxidation number 0, the oxygen atom must have an oxidation number of +2.

Oxidation Number in O₂F₂:

• In Dioxygen Difluoride (O₂F₂), there are two fluorine atoms, each with an oxidation number of -1. So, the total oxidation number contributed by fluorine is -2.
• There are also two oxygen atoms. To make the total oxidation number 0, the combined oxidation number of the two oxygen atoms must be +2.
• Therefore, the oxidation number of each oxygen atom in O₂F₂ is +1 (because +2 divided by 2 equals +1).

So, in OF₂ and O₂F₂, the oxygen is assigned an oxidation number of +2 and +1, respectively. Therefore, the correct answer is B: +2 and +1.

According to option A chiral compound at least have one chiral carbon but compounds other than carbon and also chiral like NCl Br I is chiral. According to option b a compound containing only one ka kalakaron is always is always correct that is statement is true it is the minimum requirement for a carbon atom to become chiral. Efficiency is not necessary to be true all the time compound will not be superimposable on its Mirror image. And for option d a plane of symmetry is sufficient but not a mandatory to give achiral compound.

Mn²⁺/ Mn have - 1.18SRPvalue.

As the temperature increases, so does the rate of reaction. But very high temperatures denature enzymes.The enzyme activity gradually increases with temperature up to around 37^oC, or body temperature.

In a chemical reaction, chemical equilibrium is the state in which the forward reaction rate and the reverse reaction rate are equal. The result of this equilibrium is that the concentrations of the reactants and the products do not change. However, just because concentrations aren’t changing does not mean that all chemical reaction has ceased. Just the opposite is true; chemical equilibrium is a dynamic state in which reactants are being converted into products at all times, but at the exact rate that products are being converted back into reactants. The result of such a situation is analogous to a bridge between two cities, where the rate of cars going over the bridge in each direction is exactly equal. The result is that the net number of cars on either side of the bridge does not change.

Measure of the amount of organic material in the water, in terms of how much oxygen will be required to break it down biologically is termed as Biochemical Oxygen Demand (BOD)

The correct answer is option A

The cells will be arranged as such 9 : 4: 1.

Explanation:

• The equilibrium constant that is used here is represented with k.

• The smaller the value of k the higher will be the value of energy according to Gibbs.

• So, 1 has the highest Gibbs free energy while 9 has the least.

• This is the energy of a chemical reaction.

• It is represented by G.

-COOH is carboxyl group.

i (van’t Hoff factor) = 1 + (y — 1) x = (1 + 2 x)

∴ π, (osmotic pressure) = MRTi = 0.004 x R x 300 x (1 + 2x)

Glucose is a non-electrolyte.
Hence,

i = 1

π₂ = mRTi = 0.01 x R x 300 x 1 Two solutions are isotonic, hence

Greater the electronegativity of carbon atom
(sp³ < sp² < sp)
Greater the attraction for (C— H) bonding pair hence, shorter the (C— H)bond.

The amount of energy that is required to break a chemical bond in a molecule into individual atoms is known as bond enthalpy. 435.8 kJ mol^-1 is required to dissociate a hydrogen molecule into two hydrogen atoms.

The correct answer is option B.
Water in oil (w/o) type : In these emulsions, water is in the dispersed phase and oil is in the dispersion medium. For example: butter, cold cream etc. They are also called oil emulsions.

TiO > VO > CrO > FeO with the decrease in size of metal atom from Ti to Fe, the basic character of their monoxides decreases.

Given a set of quantum numbers, n=2,l=0 for a multi-electron atom refers to 2s orbital. 

The next higher allowed set of 'n' and 'l' quantum numbers for this atom in the ground state is n=2,l=1. This corresponds to 2p orbital.

Note: The orbital with a higher value of the sum (n+l) has higher energy.

For 2s orbital (n+l)=(2+0)=2

For 2p orbital (n+l)=(2+1)=3

The IUPAC name of the given compound is 5, 6 - diethyl -2- methyldec - 4 - ene. 
The parent hydrocarbon contains 10 carbon atoms and a double bond. 
It is called dec-4-ene.
One methyl group is present on second carbon atom and two ethyl groups are present on fifth and sixth carbon atoms.
