Among the groups of elements listed below, which have the same number of electrons in their outermost energy levels?
O NP. As, Sb
None of these
OK, Ca, Rb, Sr
OLI, B, C F
O Na Mg, ALS

Answers

Answer:

N, P, As, Sb

Explanation:

Elements present in the same group having same number of valence electrons. The first option is correct from given options because nitrogen, phosphorus, arsenic and antimony are present in same group thus having same number of electrons in outer most  energy level.

Electronic configuration of N:

N₇: [He] 2s² 2p³

Electronic configuration of P:

P₁₅: [Ne] 3s² 3p³

Electronic configuration As:

As₃₃: [Ar] 3d¹⁰ 4s² 4p³

Electronic configuration Sb:

Sb₅₁: [Kr] 4d¹⁰ 5s² 5p³

Here it is clear from electronic configuration all these elements have five number of valence electrons.

A student is able to lift 500N weight by applying 100N. What is the mechanical advantage of a simple machine?

Answers

Explanation:

Load=500N

Effort=100N

Now,

We have,

Mechanical advantage= Load / effort

= 500/100

=5

Therefore, mechanical advantage is 5.

Methanol, propan-1-ol and ethanol has boiling point of 65 degree celsius, 97 degree celsuis, 87 degree celsuis respectively. A student uses fractional distillation to separate a mixture of these compound. State which liquid will be collected in the second fraction and explain why

Answers

Answer:

ethanol

Explanation:

Methanol has a boiling point of 65°C, propan-1-ol has a boiling point of 97°C and ethanol has a boiling point of 87°C

Fractional distillation is used for separating miscible liquids through the use of the different vapor pressure properties of the liquids. As the mixture is heated up, components start to vaporize according to their boiling points. The component with the least boiling point vaporizes first while the component with the highest boiling point vaporizes last.

This means that methanol would vaporize at the first fraction because it has the lowest boiling point followed by ethanol at the second fraction and then propan-1-ol at the last fraction.

Is the average atomic mass of a sample containing three lithium-6 and two lithium-7 closer to the mass of Li-6 or Li-7 ?

Answers

The average atomic mass of a sample closer to the mass of Li-6

Further explanation  

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.  

So Isotopes are elements that have the same Atomic Number (Proton)  

Atomic mass is the average atomic mass of all its isotopes  

In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu  

Mass atom X = mass isotope 1 . % + mass isotope 2.%  

three Li-6, mass number = 6

two Li-7, mass number = 7

total abundance = 5

abundance for Li-6 =

[tex]\tt \dfrac{3}{5}\times 100\5=60\%[/tex]

abundance for Li-7 =

[tex]\tt \dfrac{2}{5}\times 100\5=40\%[/tex]

Average atomic mass :

[tex]\tt (0.6\times 6)+(0.4\times 7)=6.4[/tex]

i am thinking Li & CI :)

Answer:

I searched the answer up on Brainly so its not my credit.

Explanation:

The answers D.

"If you have learned that metal + nonmetal ⟶ ionic bond, the answer is D, because N and C are the only pair of nonmetals.

However, if you have learned that a bond is ionic if the electronegativity difference (ΔEN) between the two atoms is greater than 0.7, the answer is A, B, and D.

The Li-Cl bond is definitely ionic.

For Na and C, ΔEN =1.62, so the Na-C bond is a highly polar covalent bond.

For Mg and C, ΔEN = 1.24, so the Mg-C bond is a polar covalent."

Describe how sodium (Na) and chlorine (Cl) interact to form an ionic compound. Specifically, what is happening to an electron?

Answers

When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.

As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt.

Would you expect manganese(II) oxide, MnO, to react more readily with HF(aq) or NaOH(aq)?

Answers

Answer:

NaOH(aq)

Explanation:

NaOH(aq) is known to precipitate Mn^2+ ions according to the following reaction; Mn^2+(aq)+2OH^−(aq)↽−−⇀Mn(OH)2(s)

Hence, manganese(II) oxide reacts more readily with NaOH(aq) under ordinary conditions precipitating the metal hydroxide solid. This is one of the characteristic reactions of Mn^2+.

What is a spinning body?

A body which rotates in its own axis is called a spinning body. Earth rotates about its along with revolving around sun.  The outer core of earth generates electric current. This is called telluric current.

Flow of this current creates an electric current which is parallels to the surface of earth. The direction of magnetic field lines will be perpendicular to the direction of current. But it comes stronger when parallel to current.

A rotating electric current results in the generation of a magnetic field. Thus spinning of  earth core generates a magnetic field and therefore, option D is correct.
