Answer: The correct answer is Option B.

Explanation:

A covalent bond is formed when sharing of electrons takes place between the atoms combining. The atom which attracts the shared pair of electron towards itself is more electronegative and the atom which does not attracts the shared pair of electron towards itself is less electronegative.

In HCl molecule, more electronegative atom is chlorine atom having an electronegativity of 3.16 and hydrogen has an electronegativity of 2.1

So, majority of shared electrons will be found near to the chlorine atom in hydrochloric molecule.

Hence, the correct answer is Option B.

Hey there! The answer to your first question is SILICON, Nickle has 28 protons, silicon has 14, 14+14=28. Its the only element thats adds up. I dont know about the 2nd one myself.

A stealth bomber is moving at 799km/h west and travels to a top velocity of 1,1325km/h west in 4.8 minutes.

maria [59]

Answer:

10.1 ms^-2

Explanation:

From;

v = u + at

v = final velocity

u = initial velocity

a= acceleration

t = time taken

To convert the velocity from Km/hr to m/s we us;

x * 1000/3600

Where x is the velocity in Km/hr

So;

799 * 1000/3600 = 221.9 m/s

11325 * 1000/3600 = 3145.8 m/s

4.8 minutes = 4.8 * 60 = 288 s

Applying the formula;

a= v - u/t

a = 3145.8 - 221.9/288

a = 10.1 ms^-2

Consider the following reaction at 298 K.

Jlenok [28]

Answer and Explanation:

The reaction is in the gas phase, so the equilibrium constant is expressed in terms of the partial pressures (P) of the products and reactants, as follows:

$Kp = \frac{P^{2}_{SO_{3} } }{P_{SO_{2}} ^{2}P_{O_{2}} }$

We have the following data:

P(SO₃) = 2.6 atm

P(O₂) = 0.43 atm

We need Kp for this reaction. We can assume that in Appendix 4 we found that Kp = 7 x 10²⁴.

Then, we introduce the data in the equilibrium constant expression to calculate the partial pressure f SO₂ (PSO₂), as follows:

$P_{SO_{2} } = \sqrt{\frac{P_{SO_{3} } ^{2} }{Kp P_{O_{2} } } } = \sqrt{\frac{(2.6 atm)^{2} }{(7 x 10^{24)}(0.43 atm) } } = 1.5 x 10^{-12} atm$

Therefore, the partial pressure of SO₂ is 1.5 x 10⁻¹² atm (for the given Kp).

Why potasium more reactive than lithium and sodium

frez [133]

So potassium is more reactive than lithium because the outer electron of a potassium atom is further from its nucleus than the outer electron of a lithium atom. Hope this answers the question. Have a nice day. Feel free to ask more questions.

The atomic number,atomic mass,valence electrons and the formula for calculating the number of neutrons is also given.The following table has been completed below in the attachment.

Explanation:

Atomic Number:the number of protons /electrons present in the nucleus of an atom is called the atomic number.

Mass Number/Atomic Mass:the number of protons and neutrons present in a nucleus

Example: $C_{6} ^{12}$ ;here;6 implies the atomic number and 12 implies the mass number/atomic mass

No.of neutrons=Mass number-Number of protons

Valence electrons:the number of electrons present in the outer most shell of an atom are called valence electrons

Example:If we consider a carbon atom;as its electronic configuration is2,4 and it belongs to 4th group.Therefore the number of valency electrons in carbon is 4.
