Answer:

Mg(s) + Sn²⁺(aq) ⇄ Mg²⁺(aq) + Sn(s)

Explanation:

Let's consider the following molecular equation.

Mg(s) + SnSO₄(aq) ⇄ MgSO₄(aq) + Sn(s)

The full ionic equation includes al the ions and the species that do not dissociate in water.

Mg(s) + Sn²⁺(aq) + SO₄²⁻(aq) ⇄ Mg²⁺(aq) + SO₄²⁻(aq) + Sn(s)

The net ionic equation includes only the ions that participate in the reaction (not spectator ions) and the species that do not dissociate in water.

Mg(s) + Sn²⁺(aq) ⇄ Mg²⁺(aq) + Sn(s)

Arrange the following molecules in order of decreasing polarity of their bonds.
polet [3.4K]

Answer:

SF2 > H2O > PBr3 > NCl3

Explanation:

Compare the electronegativity values for the atoms and classify the nature of the bonding based on the electronegativity difference.

P has an electronegativity of 2.1, while Br has an electronegativity of 2.96. The difference is 0.86, indicating that these atoms will form covalent bonds.

S has an electronegativity of 2.58 while F has an electronegativity of 4.0. The difference is 1.42, indicating that these atoms will form polar covalent bonds.

O has an electronegativity of 3.5 while H has an electronegativity of 2.1. The difference is 1.4, indicating that these atoms will form polar covalent bonds.

N has an electronegativity of 3.04, whereas Cl has an electronegativity of 3.5. This difference of 0.46 indicates that these atoms will form covalent bonds.

We know that the greater the electronegativity, the higher the polarity. In decreasing order of polarity, we have:

SF2 > H2O > PBr3 > NCl3

Xenon (xe) of mass 5.08 g reacts with fluorine to form 9.49 g of a xenon fluoride compound. what is the empirical formula of thi
jenyasd209 [6]
We are already given with the mass of the Xe and it is 5.08 g. We can calculate for the mass of the fluorine in the compound by subtracting the mass of xenon from the mass of the compound.

  mass of Xenon (Xe) = 5.08 g
  mass of Fluorine (F) = 9.49 g - 5.08 g = 4.41 g

Determine the number of moles of each of the element in the compound. 
    moles of Xenon (Xe) = (5.08 g)(1 mol Xe / 131.29 g of Xe) = 0.0387 mols of Xe
   moles of Fluorine (F) = (4.41 g)(1 mol F/ 19 g of F) = 0.232 mols of F

The empirical formula is therefore,
      Xe(0.0387)F(0.232)
Dividing the numerical coefficient by the lesser number.

katrin [286]

Answer:

The answer is "5.4".

Explanation:

BoH + HCL =BCL +H_2o \\\\At eq \\\\N_1V_1=N_2V_2 \\\\v_2=20 \ ml\\\\[BCL]=\frac{20 \times 0.08}{20+20}=0.04\\\\pH = \frac{1}{2} [pkw - pk_b - \log e]\\\\pk_b = 2 pH - Pkw + \Log C\\\\pK_b=5.4

Lithosphere: Odd one out . Analyze each part of the rectangle. One of the parts will be different from the others. Shade the par
patriot [66]

The characteristics of the lithosphere found that the frame that is out of sequence is:  

       last frame: Iron

The lithosphere is the upper part of the Earth, it is composed of two parts: the crust and the upper part of the mantle, up to the ionosphere, an area of ​​material in a plastic state.

The lithosphere is the most important part for since all the life processes on the planet occur in it, the depth of the lithosphere is greater in the continental part about 250 km than in the oceanic part 150 km, this is It is because it is floating above the stratosphere.

Let's analyze each part of the picture

1. Rigid rocks in the upper part of the mantle.

The lithosphere is the coldest part of the plant, which is why the rocks have solidified, forming a rigid layer of rocks that floats on the mantle.

2. Crust.

It is another name given the uppermost part of the lithosphere, it is formed by a solid area,

3. Tectonic plates.

The lower part of the lithosphere is on an area in a very hot platic state, therefore there is a thermal gradient between the convection current of the asthenosphere and the thermal conduction of the lithosphere, these thermal gradients create breaks or divisions in the upper layer that we call plate tectonics

4.) solid crust of the Earth

The lithosphere is by definition the solid part of the Earth, which is why it is also called solid crust, but not rigid.

5) Continents.  

They are the highest parts of the lithosphere, they are above the average height of the oceanic that forms the liquid part that fills the lower spaces of the lithosphere, in general it is formed by rocks of granite composition

6) Earthquakes

The plates of the lithosphere can move between it, in some cases these plates are locked (stopped) accumulating energy at some point the rocks that form part and the plates move abruptly this movement is called an earthquake

7) Volcanoes

The lower part of the lithosphere is hotter, in some parts where the upper rock is more fragile, this heat can fragment them, which is why the molten rock called magna has an exit path towards the earth's surface, in general the fragmentation processes and rupture is accompanied by high pressures that make the surface rise in height, these structures are called volcanoes, the vast majority are near the contact zone of the tectonic plates,

8) Iron  

This is a chemical element that is one of the constituents of the lithospheres, but it is not an essential part of its structure. Iron, for being a heavy element, is believed to be fundamentally in the Earth's nucleus, in the lithosphere it only forms 4.7% of its structure. This is why this box is out of sequence of the second rectangle

Consequently with the characteristics of the lithosphere found that the frame that is out of sequence is:

              last frame: Iron
