B. It would increase.
C. It would stay the same.
D. You cannot tell from this graph.

Answer:

See explanation

Explanation:

We know that

%ic of the interatomic bond = [1 - e^-(XA - XB)^2/4] * 100%

Now;

XA = electronegativity of Ti = 1.61

XB = electronegativity of Al = 1.54

Substituting values;

%ic of the interatomic bond = [1 - e^-(1.61 - 1.54)^2/4] * 100%

%ic of the interatomic bond = 0.12%

Given the low %ic of the interatomic bond, the bond is metallic.

The percent ionic character is 0% and the type of interatomic bonding would be metallic.

The percent ionic character can be determined by using the formula,

[tex]1-exp{-0.25(Xa-Xb)^{2} ][/tex]

• In the given equation, Xa and Xb refers to the electronegativities of the elements.  

• The intermetallic compound given is TiAl₃.  

• Based on the electronegativity table, the electronegativity of Al or Xa is 1.5 and the electronegativity of Ti or Xb is 1.5.  

Now putting the values in the above formula we get the % ionic character,

[tex]= 1-exp [-0.25 (Xa -Xb)^{2}]*100%\\\\\\=1-exp [-0.25 (1.5 -1.5)^{2}]*100%\\[/tex]

[tex]= 0 percent[/tex]

Thus, the ionic bond character is 0% and the compound TiAl₃ comprises two metals, it exhibits metallic bonding.

Answer:

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction.

Magnets exert magnetic force as a result of magnetic field attraction between opposite poles and magnetic field repulsion between same poles.

Magnets are the substance in which north and south poles present and they show attraction towards the different poles and repulsion towards the same pole.

Due to presence of this poles magnets have their own magnetic field and direction of this field governs from north to south pole. Due to this magnetic field magnets exert magnetic force towards some metals like iron and show attraction.

Hence, due to presence of different poles in a magnet, they exerts  magnetic force.

Explanation:

Answer:70L

Explanation:

The volume occupied by 100g of oxygen gas at STP is 70L.

1 mole of a gas at STP occupies 22.4 L volume.

The same goes for oxygen gas, [tex]O_2[/tex]. 1 mole of [tex]O_2[/tex] occupies 22.4L volume.

Now the molar mass of [tex]O_2[/tex] is = 32g

So the number of moles of [tex]O_2[/tex] in 100g is

n = 100/32

n = 3.125 moles

Volume occupied by 3.125 moles or 100g of [tex]O_2[/tex] is

V = 3.125 × 22.4 L

V = 70 L volume is occupied by 100g of oxygen gas.

Answer:

85.6 g

Explanation:

Step 1: Write the balanced combustion equation

C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O

Step 2: Calculate the moles corresponding to 140 g of H₂O

The molar mass of H₂O is 18.02 g/mol.

140 g × 1 mol/18.02 g = 7.77 mol

Step 3: Calculate the moles of C₃H₈ needed to produce 7.77 moles of H₂O

The molar ratio of C₃H₈ to H₂O is 1:4. The moles of C₃H₈ needed are 1/4 × 7.77 mol = 1.94 mol.

Step 4: Calculate the mass corresponding to 1.94 moles of C₃H₈

The molar mass of C₃H₈ is 44.10 g/mol.

1.94 mol × 44.10 g/mol = 85.6 g

An artificial reef is intended to affect the ocean ecosystem by providing shelter and habitat for marine organisms causing sediment to erode into deeper waters. Hence, option C is correct.

An artificial reef is a human-made underwater structure, typically constructed with the purpose of enhancing marine biodiversity, providing habitat for marine organisms, and promoting recreational activities like fishing, diving, and snorkeling.

Artificial reefs can be created from a variety of materials, such as concrete, metal, tires, and sunken ships. The reef structure can also increase the overall biodiversity of an area by creating a new habitat for species that may not have been present before.

Additionally, the presence of an artificial reef can help to reduce pressure on natural reefs by providing an alternative location for fishing and other activities. However, artificial reefs are not typically used as a means of removing pollution from the water or preventing erosion.

Therefore, option C is correct.

Answer:

Explanation: The answer is B. Because meiosis process produce genetically different, haploid cells. Also, meiosis basically happen to produce gametes. Gametes is haploid. So, the answer is B

Meiosis is a method for cell division taking place in some organisms. In meiosis the cell the cells produced at the end of meiosis contain half the number of chromosomes as the parent cell. Hence, option C is correct.

meiosis is biological process by which the cell undergo division to produce genetically identical daughter cells. Other methods of cell divisions include mitosis, binary division, budding etc.

The first stage of meiosis includes pairing homologous chromosomes and they segregate to opposite ends of the meiotic spindle.This phase is known as reduction division where, the number of chromosome reduces to half.

This differentiated chromatids separates out in the second phase and yielding the haploid cells. Hence, in meiosis, the cells produced at the end of meiosis contain half the number of chromosomes as the parent cell.
