Zinaida [17]2 years ago

The electron configuration of  V³⁺ is [Ar]3d^2. The ion is paramagnetic because it has two unpaired electrons

<h3>What is paramagnetic?</h3>
  • A weak magnetic field supplied externally can weakly attract some materials, which then create internal magnetic fields that are directed in the same direction as the applied magnetic field. This phenomenon is known as paramagnetic.
  • Diamagnetic materials, in contrast, are attracted to magnetic fields and produce induced magnetic fields that are directed in the opposite direction from the applied magnetic field.
  • The majority of chemical elements and some compounds are considered to be paramagnetic materials.
  • Paramagnetic materials have a relative magnetic permeability that is somewhat more than 1, which makes them attracted to magnetic fields.
  • The applied field induces a linearly decreasing magnetic moment that is relatively weak.
  • Modern experiments on paramagnetic materials are frequently done with a sensitive analytical balance since it typically requires a sensitive analytical balance to identify the effect.

A force of 20 N acts upon 5 kg block caculate the accerleration of the object
Vedmedyk [2.9K]

Answer:

\boxed{\text{4 m $\cdot$ s$^{-2}$}}

Explanation:

F = ma

a = \dfrac{F}{m} = \dfrac{\text{20 N}}{\text{5 kg}} \times \dfrac{\text{1 kg$\cdot$ m $\cdot$ s$^{-2}$}}{\text{1 N}} = \text{4 m $\cdot$ s$^{-2}$}\\\\\text{The acceleration of the object is } \boxed{\textbf{4 m $\cdot$ s$^{\mathbf{-2}}$}}

What is the most likely reason that nonmetals are electrical insulators?
Ray Of Light [21]

Answer:

Since valence shells are mostly empty in nonmetal atoms, the atoms attract and hold any electrons they can in order to fill their valence shells.

1. Compound A contains 14 g of nitrogen for each 16 g of oxygen. Compound B contains 14 g of nitrogen for each 32 g of oxygen. W
Sever21 [200]

Answer:

The lowest whole number mass ratio of nitrogen that combines with a given mass of oxygen is 1:1

Explanation:

In compound A, we have 14 g of nitrogen combine with  16 g of oxygen

In compound B, we have 14 g of nitrogen combine with  32 g of oxygen

Therefore,  we have

                                                                  A                            B

Ratio of molar masses                               14:16                 14:32

Mass of O that combine with 1 g of N       1.14                   2.29

Dividing by the smallest mass ratio          1                        2

Therefore the lowest whole number mass ratio at which oxygen and nitrogen can combine = 1:1.

36.4 g of SnCl2 is dissolved in 135.7 mL of water.
Yuki888 [10]

Answers:

1st: 189.6 g/mol

2nd: 0.1357 L

3rd: 1.41 M

Explanation:

Finding Molar Mass:

SnCl2 = <u>Tin(II) Chloride</u>

Tin has a molar mass of <u>118.71 g/mol</u>

Chloride has a molar mass of <u>35.453 g/mol</u>

Chloride*2 = <u>70.906</u>

<u>118.71 + 70.906 ≈ 189.6 g/mol</u>

Finding Liters of Solution:

L = mL/1000

135.7 mL / 1000 = <u>0.1357</u>

Finding Molarity:

molarity = <u>moles of solute / liters of solution</u>

M = (36.4g /  189.6g) / 0.1357 L = <u>1.41 M</u>

Hope this helped ;)
