O Na and BrCI
O Na and BrCl2
O NaCl and Br2
O Na(Cl)2 and Br2

Explanation:

Load=500N

Effort=100N

Now,

We have,

Mechanical advantage= Load / effort

= 500/100

=5

Therefore, mechanical advantage is 5.

For a fence is 2 meters feet tall, the fence is 183.92 centimeters tall.

There are 0.3048 meters in 1 foot. So, a 2 meters fence is equal to 2 x 0.3048 = 0.6096 feet tall.

To convert feet to centimeters, multiply the number of feet by 30.48. So, a 0.6096 feet fence is equal to 0.6096 x 30.48 = 183.92 centimeters tall.

Therefore, the fence is 183.92 centimeters tall.

Feet to centimeters:

1 feet = 30.48 centimeters

0.6096 feet × 30.48 centimeters/feet

= 183.92 centimeters

Explanation:

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.

Answer:

The atomic mass is 101.

Explanation:

Protons and neutrons are the only particles that contribute to mass. Electrons do have a mass, but it's so miniscule and insignificant that it doesn't contribute to the mass of an atom. In every instance of calculating atomic mass, add the number of protons to the number of neutrons.

Therefore,

44 + 57 = 101

number of protons + number of neutrons = atomic mass

Also, there can never be a negative amount of protons or neutrons, so if you get a negative number, there's something wrong.

Bonus Information:

Don't confuse mass with charge! As it says in its name, neutrons are neutral or have no charge. Protons (+) and electrons (-) are the only particles that have a charge, so calculating that would be different.

If you were calculating the atomic charge with the same numbers, your answer would be:

44 - 42 = 2

Charge = +2

What To Remember:

M = p + n

C = p - e

C = atomic charge, M = atomic mass, p =protons, n = neutrons, e = electrons

Explanation:

Answer: Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.

Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.

Explanation:

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

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 :

Answer:

c

Explanation:

Earth contains a spinning electric filed. The spinning of earth core creates its magnetic field. Thus, option D is correct.

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.

#SPJ2

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."
