Which of the following metals (M) will form an ionic compound with nitrogen with the general formula M3N2? Hint: Think about how
Basile [38]

Answer:

See explanation

Explanation:

The question is incomplete but i will try to give you all the necessary guide that you need in order to answer the question.

When compounds are formed, atoms exchange valency. The valency of nitrogen is three while that of the metal is two. The exchange yields M3N2.

If the compound has been specifically mentioned to be a metal, then it must be a group two element. It could be any of Mg, Ca, Sr, Ba or Ra. I did not mention Be here because most of its compounds are covalent.

This will help you to answer the complete question.

Using Charles law if the volume of a gas is 5.0 L when the temperature is 5.0C what will the new volume be if the temperature is
Vikentia [17]

Answer:

The answer to your question is   V2 = 5.09 l

Explanation:

Data

Volume 1 = V1 = 5.0 L

Temperature 1 = T1 = 5°C

Volume 2 = V2 = ?

Temperature 2 = T2 = 10°C

Formula (Charles law)

             V1/T1 = V2/T2

-Solve for V2

                  V2 = V1T2 / T1

-Convert temperature to °K

T1 = 5 + 273 = 278°K

T2 = 10 + 273 = 283°K

-Substitution

                 V2 = (5)(283) / (278)

-Simplification

                 V2 = 1415 / 278

-Result

                 V2 = 5.09 l

A cylindrical glass bottle 21.5 cm in length is filled with cooking oil of density 0.953 g/mL. If the mass of the oil needed to
jeka57 [31]

Answer:inner Diameter =9.19cm

Explanation:

Density is calculated as Mass/ Volume

therefore

Volume= Mass/ Density = 1360g/ 0.953g/ml=1,427 ml

1ml = 1cm³

1,427ml = 1,427cm³

Also We know that Volume of a cylinder = πr²h or  πr²l

1,427cm³ = 3.142 x r² x 21.5 cm

 r² =  1,427cm³/ (3.142 x 21.5cm)

r² =21.124cm²

\sqrt{21.124}= r²

r= 4.596cm

Diameter=  2 x radius

=2 x 4.596

=9.19cm

What are the combinations attached groups, atoms, or lone pairs you can add to a central atom?
Mazyrski [523]

Answer:

Hello your question is poorly written below is the well written question

Explore what molecules you can build From Lewisstructureandmoleculargeometry . What are the combinations attached groups, atoms, or lone pairs you can add to a central atom?

answer :

  • when there are three ( 3 ) groups and a lone pair the shape of the molecule will be pyramidal but when the three ( 3 ) groups does not have any lone pair attached to it, the shape of the molecule will be trigonal planar
  • When there are two groups and  two lone pairs the shape of the molecule will be bent while when there are two groups without lone pairs the shape of the molecule will be linear

Explanation:

From molecular Geometry changes there are two groups to be considered here and they are group and lone pairs

<u>The combinations that can be added to a central atom </u>

when there are three ( 3 ) groups and a lone pair the shape of the molecule will be pyramidal but when the three ( 3 ) groups does not have any lone pair attached to it, the shape of the molecule will be trigonal planar

When there are two groups and  two lone pairs the shape of the molecule will be bent while when there are two groups without lone pairs the shape of the molecule will be linear
