this is hard

Explanation:

The polyatomic ions are those ions which has more than two atoms involved such as the other options than OH^-1 in the question. The OH^-1 ion is the diatomic ion because it has only 2 atoms

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.

Answer:

Combination reaction

Explanation:

In Chemistry, elements and compounds are involved in a process called chemical reactions, which are of different types namely: combination, decomposition, double replacement, combustion etc. A combination reaction is that reaction in which two or more substances called the REACTANTS combine together to form a single new substance called the PRODUCT.

In this case, a reaction is depicted as follows:

2SO2(g) + O2(g) --> 2SO3(g)

In this reaction, compound SO2 combines chemically with element O2 to form a single new compound SO3. Hence, this is a type of COMBINATION REACTION.

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."

Answer:

36V

Explanation:

Given parameters:

Number of turns in primary coil  = 150turns

Secondary coil turn = 50turns.

Input voltage  = 12V

Unknown:

Output voltage  = ?

Solution:

For this transformer problem, we use the expression;

   [tex]\frac{N_{s} }{N_{p} }[/tex]   = [tex]\frac{V_{s} }{V_{p} }[/tex]  

Insert the parameters and solve;

        Ns is the number of secondary turns

        Np is the number of primary turns

         Vs is the secondary voltage

          Vp is the secondary voltage

Insert the parameters and solve;

          [tex]\frac{150}{50}[/tex]   = Output voltage / 12

          Output voltage = 12 x 3  = 36V

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 :

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

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+.
