Which is a constructive process? Rivers carrying sediment down stream, the rusting of a bridge, waves cutting back a beach front, volcanic eruption caused by plate tectonics

The option which isn't a result of surface tension in water is: c. surface area is maximized.

Water can be defined as a liquid molecule that comprises the chemical element hydrogen and oxygen in the ratio of two to one (2:1).

Surface tension can be defined as a property of liquid such as water, which makes its surface to resist an external force due to the cohesive nature of its molecules.

This ultimately implies that, the surface tension of a liquid is mainly as a result of the cohesive forces existing between its molecules.

Generally, the surface tension of water is typically higher than the surface tension of most liquids.

Due to the effect of surface tension in water;

Additionally, the surface tension of a liquid such as water can be described as an inward force which tends to minimize its surface area rather than maximize its surface area.

In conclusion, surface tension in water doesn't maximize its surface area.

Taking into account the definition of molecular geometry, the correct option is option d.:  the bond angle of a linear molecule is 180 degrees.

In first place, molecular geometry or molecular structure is the spatial distribution of atoms around a central atom. Atoms represent regions where there is a high electron density, and are therefore considered electronic groups, regardless of the bonds they form.

That is, molecular geometry is the three-dimensional arrangement of the atoms that make up a molecule.

The molecular geometry of an element characterizes some of its physical or chemical properties, such as boiling point, viscosity, and density.

Linear molecules are molecules of the AB₂ type in which the central atom does not have lone pairs. To avoid repulsions between the binding pairs, arrange the B groups as far apart as possible. For that they must oppose each other 180 °.

In summary, linear molecular geometry describes the arrangement of different atoms with 180º bonds.

So, the correct option is option d.:  the bond angle of a linear molecule is 180 degrees.

Answer:

d. 46.5 g

Explanation:

First, you need to start with a properly balanced equation:

N₂H₄(l) + 3O₂(g) -> 2NO₂(g) + 2H₂O(l)

Then, find the moles of water produced:

2H = 2.01568 amu

O = 15.999 amu

________________

18.01468 amu

52.4 g ÷ 18.01468 amu = 2.9087 moles

The mole ratio in our balanced formula between N₂H₄ : H₂O is 1 : 2, so divide moles of H₂O by 2 to get moles of N₂H₄

2.9087 moles ÷ 2 = 1.45435 moles of N₂H₄

Then, calculate the atomic mass of N₂H₄:

2N = 28.0134 amu

4H = 4.03136 amu

________________

32.04476 amu

Finally, calculate the mass in grams of N₂H₄:

1.45435 moles • 32.04476 amu = 46.604 g

because its Saturated

Answer:

Opposite.

Water exhibits negative charge near hydrogen, positive near oxygen.

This is why it is OPPOSITE.

Let me know if this helps!

Water is a polar compound because it exhibits opposite charges. Therefore, option C is correct.

The term polar compound is defined as the compound with distinct regions of positive and negative charge, as a result of bonding with atoms such as nitrogen, oxygen, or sulfur.

Water is a polar compound because the covalent bonds between hydrogen and oxygen in the water molecule are polar in nature. Any molecule with lone pairs of electrons around the central atom is polar compound.

In water there are two atoms are present that are oxygen and hydrogen. Hydrogen has positive charge while oxygen has negative charge,

Thus, Water is a polar compound because it exhibits opposite charges, option C is correct.

[tex]\boxed {\boxed {\sf 3 \times 10^{21} \ atoms \ Hg}}[/tex]

Explanation:

We are asked to find how many atoms are in 1 gram of mercury.

First, we convert grams to moles. We use the molar mass or the mass of 1 mole of a substance. These values are equivalent to the atomic masses on the Periodic Table, but the units are grams per mole instead of atomic mass units.

Look up mercury's molar mass.

We convert using dimensional analysis, so we create a ratio using the molar mass.

[tex]\frac { 200.59 \ g \ Hg}{ 1 \ mol \ Hg}[/tex]

We are converting 1 gram of mercury to moles, so we multiply the ratio by this value.

[tex]1 \ g \ Hg *\frac { 200.59 \ g \ Hg}{ 1 \ mol \ Hg}[/tex]

Flip the ratio so the units of grams of mercury cancel out.

[tex]1 \ g \ Hg *\frac{ 1 \ mol \ Hg} { 200.59 \ g \ Hg}[/tex]

[tex]1 *\frac{ 1 \ mol \ Hg} { 200.59}[/tex]

[tex]\frac{ 1} { 200.59} \ mol \ Hg[/tex]

[tex]0.004985293385 \ mol \ Hg[/tex]

Next, we convert moles to atoms. We use Avogadro's Number or 6.022 × 10²³. This is the number of particles (atoms, molecules, formula units) in 1 mole of a substance. In this case, the particles are atoms of mercury.

We will use dimensional analysis and set up another ratio.

[tex]\frac {6.022 \times 10^{23} \ atoms \ Hg}{ 1 \ mol \ Hg}[/tex]

Multiply by the number of moles we calculated.

[tex]0.004985293385 \ mol \ Hg * \frac {6.022 \times 10^{23} \ atoms \ Hg}{ 1 \ mol \ Hg}[/tex]

The units of moles of mercury cancel.

[tex]0.004985293385 * \frac {6.022 \times 10^{23} \ atoms \ Hg}{ 1 }[/tex]

[tex]3.00214368 \times 10^{21} \ atoms \ Hg[/tex]

The original measurement of grams has 1 significant figures, so our answer must have the same. For the number we calculated, that is the ones place. The 0 in the tenths place tells us to leave the 3 in the ones place.

[tex]3 \times 10^{21} \ atoms \ Hg[/tex]

There are approximately 3×10²¹ atoms of mercury in 1 gram of mercury.

The element that will have the lowest electronegativity is an element with a small number of valence electrons and a large atomic radius.

Electronegativity of an element is the ability or power of that element in a molecule to attract electrons to its Valence electrons.  The following are the properties of electronegativity:

Atomic radius of elements increase down a group because of a progressive increase in the number of shells occupied by electrons which increases the size. But it decreases across a period because electrons are accommodated within the same shell leading to greater attraction by the protons in the nucleus.

Answer:

The limiting reagent is CuCl

Explanation:

The initial number of moles of aluminum, Al = 4.5 moles

The number of moles of copper, Cu = 6.5 moles

The given chemical reaction is presented as follows;

2Al + 3CuCl → 2AlCl₃ + 3Cu

Therefore, we have, 2 moles of aluminum combine with 3 moles of CuCl produces 2 moles of AlCl₃ and 3 moles of Cu

1 mole of Al will combine with (3/2) moles of CuCl,

Therefore, 4.5 moles of Al will combine with (4.5 × (3/2) = 6.75) 6.75 moles of CuCl

Given that the number of moles of CuCl present is only 6.5 moles which is less than the 6.75 moles required to combine with the 4.5 moles, the 6.5 moles of CuCl limits the amount of AlCl₃ and Cu produced, and therefore the CuCl is the limiting reagent.
