Gasoline is very volatile and if not kept in a tightly sealed container will quickly fill a space with vapors at a sufficient concentration to be a fire and explosion hazard. Don't even THINK about keeping gasoline in an open container. Well, you can if it is a dense and heavier-than-air gas.

Explanation:

C2H4(g) + 2O2(g) → 2CO(g) + 2H2O(g)       ∆H1 = −758 kJ mol−1       ....1)

2C(s) + 2H2(g) → C2H4(g)                           ∆H2 = +52 kJ mol−1        ....2)

H2(g) + O2(g) → H2O(g)                               ∆H3 = −242 kJ mol−1     ....3)

Now, enthalpy of formation of carbon monoxide is given by :

∆H = ∆H1 + ∆H2 - ∆H3

∆H = ( -758 + 52 - ( -242 ) ) kJ mol−1  

∆H = −464 kJ mol−1

Therefore, the enthalpy of formation of carbon monoxide is -464 kJ mol−1.

Hence, this is the required solution.

Explanation:

The number of protons in one atom of an element determines the atom's identity, and the number of electrons determines its electrical charge. The atomic number tells you the number of protons in one atom of an element. It also tells you the number of electrons in a neutral atom of that element.

The number of protons in one atom of an element determines the atom’s atomic number.

The atomic number is the number of protons present basically in an atom's nucleus. The number of protons characterize the individuality of an element i.e., an element with 6 protons is a carbon atom, no matter however many neutrons may be prevalent.

The mass number of an element is determined by the number of protons and neutrons combined: mass number = protons + neutrons.

To determine the number of neutrons in an atom, subtract the number of protons, or atomic number, from the mass number.

The atomic number is the number of protons in a nucleus that always equals the number of electrons in orbit around that nucleus (in a nonionized atom).

Thus, it can be concluded that the atomic number is determined by the number of protons in atom.

A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust. Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties because their atoms and molecules are arranged differently.

Advertisers use the familiarity effect because companies hope that repeated exposure to their product will make people feel familiar with it and more likely to buy it.

Psychologists have even discovered that the more you see someone, the more likely you are to develop attraction for them. Even if the stimuli you are repeatedly exposed to is negative, you will find comfort in its familiarity.

We are drawn to people who appear familiar to us because familiarity provides predictability and safety." Imprinting is one such theory that is linked with familiarity.

Explanation:

We have the formula E = hf where R is the energy, h is planck's constant, and f is the frequency. (Planck's constant is about 6.62607004 × 10-34 m2 kg / s). We can put this into the formula to get the frequency equal to about 8.678 x 10^14

The chemical formula gives the ratio of atoms and elements in the compound. Therefore, option B, D is correct.

A chemical formula of a compound provides the chemical proportions of each element in a given compound or molecule. The chemical formula of a compound can be written with help of chemical symbols of elements, numbers, and symbols, such as plus (+) and minus (−) signs, dashes, commas, and brackets.

A chemical formula exhibits of no words related to the compound but can be drawn in some simple chemical structures. Chemical formulae of the compound should be limited in power than chemical names as well as chemical structural formulae.

There are two kinds of chemical formulas in chemistry: empirical formula and molecular formula.

Explanation:

Because its not related to science ,and also telling about future.

The basic oxide is an oxide-forming a base solution.

These oxides are mainly from group 1 alkaline and group 2-alkaline earth

If this oxide is dissolved in water it will form an alkaline solution

LO + H₂O --> L(OH)₂ ---> alkaline earth

L₂O + H₂O --> LOH --> alkaline

So the basic oxides  : Na₂O and MgO

Na₂O + H₂O --> NaOH (sodium hydroxide, strong base)

MgO + H₂O --> Mg(OH)₂ (magnesium hydroxide, strong base)

The aqueous solution of CO₂ , obtained by dissolving CO₂ in water

CO₂ + H₂O --> H₂CO₃ (carbonic acid)

In general, basic oxide is obtained from metal oxide, while acid oxide is obtained from non-metal oxide

Explanation:

The most accurate method of determining the volume of an object, is the water displacement method. It has the peculiar advantage of working well with irregular solids.

There are often errors that prevent exact measurements of the volume of objects. This makes the water displacement method a preferred and easier method of determining the volume of an object.

Answer:

d. 3f

Explanation:

An orbital in chemistry is defined as the wave function that defines the position of electrons in an atom.

There are four types of orbitals that include s, p, d, and f. On the basis of the quantum description, 3f orbital does not exist because in the third energy level only three sublevels are present that are s, p, and d that can hold a  maximum of 18 electrons.

Hence, the correct answer is "d.3f".

For the 3 principal orbitals, f suborbital has not been possible. Thus the orbital that could never exist according to the quantum description of the atom is 3f. Thus the correct option is d.

Quantum mechanics helps in the determination of the electron address. The electron address has been given by the 4 quantum numbers namely,

The principal quantum number gives the information to the orbital, and the azimuthal quantum number gives the information of the subshell.

The orbitals have been formed by the mixing of the bonding and anti-bonding orbital. The mixing of the 3 orbital has resulted in the 3 suborbital namely s, p, and d.

Thus for the 3 principal orbitals, f suborbital has not been possible. Thus the orbital that could never exist according to the quantum description of the atom is 3f. Thus the correct option is d.
