Chlorine is highly reactive than Silicon.

<u>Answer:</u> Chlorine will be more reactive.

<u>Explanation:</u>

Chemical reactivity is defined as the tendency of an element to loose of gain electrons.

Non-metals are the elements which gains electrons and hence, their chemical reactivity will be the tendency to loose electrons.

Their chemical reactivity increases as we move from left to right in a period because the valence shell come closer to nucleus as we move from left to right.

So, addition of new electron in the valence shell becomes easier due to greater attraction between nucleus and valence electron.

We are given:

Silicon is present in Group 14 and chlorine is present in group 17.

Hence, chlorine will be more reactive.

Given the balanced equation:
Aliun [14]

Answer:

0.4

Explanation:

Given data:

Number of moles of SrCl₂ consumed = ?

Mass of ZnCl₂ produced = 54 g

Solution:

Chemical equation:

ZnSO₄ + SrCl₂    →    SrSO₄ +  ZnCl₂

Number of moles of ZnCl₂:

Number of moles = mass/ molar mass

Number of moles = 54 g/136.3 g/mol

Number of moles = 0.4 mol

Now we will compare the moles of  ZnCl₂ with SrCl₂  from balance chemical equation.

                          ZnCl₂              :             SrCl₂

                              1                  :                1

                           0.4                 :              0.4

Thus when 54 g of  ZnCl₂ produced 0.4 moles of SrCl₂ react.

Conociendo el volumen de la solución y la masa del soluto y su masa molar, ¿qué concentración es posible determinar
NISA [10]

Answer:

Conociendo el volumen de solución, masa de soluto y su masa molar, es posible determinar: B) Concentración molar

La molaridad es la relación entre el número de moles de soluto y los litros de solución. Más:

M = No moles de solución de soluto / volumen (L)

Y a su vez los moles de soluto se encuentran por:

No moles de soluto = masa soluto / masa molar soluto

Which type of wires (copper, aluminum, or string) are ferromagnetic metals and why?
nalin [4]

Answer: Copper isn't ferromagnetic,

Aluminum isn't ferromagnetic,

String has a ferromagnetic property

Explanation: first of all it is important to understand that all materials have diamagnetic effect.

From this we can explain two distinct property which is Paramagnetism and Ferromagnetism.

1.What do we understand by a paramagnetic material?

Ans- this describes a material that doesn't retain it's magnetic property even when the magnetic field has been removed, an example is Aluminum.

2. Ferromagnetic materials describes those type of materials that even after the removal of magnetic field retains it's magnetism. A good example of this is Iron, nickel etc.

By definition ferromagnetism is a basic property ( which depends on temperature, crystal Structure, chemical composition, etc.) That gives a material that attraction to magnet's and can form permanent magnet.

So from the examples listed in the question,

1. copper doesn't follow as a ferromagnetic material because it requires so much magnetic field to operate and is so weakly magnetized.

2. We already established aluminium as a paramagnetic material because of its weak ability to retain magnetism in the absence of magnetic field.

3. String because of its component which is (iron+carbon) has the ability to form ferrous metals.
