The reactant that is consumed first in a chemical reaction, also known as the limiting reactant (or limiting reagent), limits the amount of product that can be produced.

Consider the reaction below:

One mole of N₂ cannot be used in its entirety if two moles of H₂ react with one mole of N₂, as there is not enough H₂ in the reaction. Hydrogen is the limiting reagent as a result.

In the molecule C2H4, valence orbitals of the carbon atoms are assumed to be e) sp^2 hybridized.

The set of orbitals that can energetically accept electrons to create chemical bonds is known as the valence shell. The ns and np orbitals in the outermost electron shell make form the valence shell for main-group elements.

The outside electrons engaged in bonding are called valence electrons. A particular atom can have 0 to 7 valance electrons since valance electrons can only exist in the s and p orbitals. Noble gases are atoms that have no valence electrons and dislike forming bonds.

Answer:

2 atoms

Explanation:

When water is boiling, adding heat does not increase the temperature. Correct option is d.

When water reaches its boiling point, which is 100°C (212°F) at standard atmospheric pressure, any additional heat supplied will not increase its temperature. Instead, the added heat is utilized to convert water from its liquid state to vapor through a process called phase transition.

During this phase change, the temperature remains constant as the extra energy is used to break the hydrogen bonds between the water molecules, allowing them to escape as steam. This is why the temperature does not increase even when more heat is added to boiling water.

Answer:

124225.91 g of Na₃PO₄

Explanation:

From the question given above, the following data were obtained:

Number of atoms of Na₃PO₄ = 4.56×10²⁶ atoms

Mass of Na₃PO₄ =?

From Avogadro's hypothesis,

6.02×10²³ atoms = 1 mole of Na₃PO₄

Next, we shall determine the mass of 1 mole of Na₃PO₄. This can be obtained as follow:

1 mole of Na₃PO₄ = (23×3) + 31 + (16×4)

= 69 + 31 + 64

= 164 g

Thus,

6.02×10²³ atoms = 164 g of Na₃PO₄

Finally, we shall determine the mass of Na₃PO₄ that contains 4.56×10²⁶ atoms. This can be obtained as follow:

6.02×10²³ atoms = 164 g of Na₃PO₄

Therefore,

4.56×10²⁶ atoms = (4.56×10²⁶ × 164)/6.02×10²³

4.56×10²⁶ atoms = 124225.91 g of Na₃PO₄

Therefore, 124225.91 g of Na₃PO₄ contains 4.56×10²⁶ atoms

Explanation:

36.607 kJ of heat are needed to warm 12.0 g of ice.

By deducting the total enthalpies of all the reactants from the total enthalpies of the products, the reaction enthalpy is determined. According to mathematics, tH is equal to the sum of the enthalpies of the reactants and the product.

The following formula can be used:

q1 = m ×Cice × ΔT1

When we change the values, we obtain:

q1 = 12.0 g ×2.09 J/g⋅∘C × 11.0°C

q1 = 273.48 J or 0.27348 kJ

We must apply the following formula to melt the ice at 0 degrees Celsius:

q2 = m * ΔHfus

where m is the mass of the ice (12.0 g), q2 is the necessary heat, and Hfus is the heat of fusion for water (334 J/g).

When we change the values, we obtain:

q2 = 12.0 g × 334 J/g

q2 = 4008 J or 4.008 kJ

We can use the formula below to warm the water from 0°C to 100°C:

q3 = m * Cwater * ΔT2

When we change the values, we obtain:

q3 = 12.0 g × 4.18 J/g⋅∘C * 100°C

q3 = 5025.6 J or 5.0256 kJ.

The following formula must be used to bring the water to a boil at 100°C:

q4 = m * ΔHvap

When we change the values, we obtain:

q4 = 12.0 g × 2257 J/g

q4 = 27,084 J or 27.084 kJ.

Lastly, we may apply the following formula to raise the steam's temperature from 100°C to 109°C:

q5 = m × Csteam × ΔT3

When we change the values, we obtain:

q5 = 12.0 g × 2.01 J/g⋅∘C × 9°C

q5 = 216.36 J or 0.21636 kJ

The total heat required is the sum of all these values:

Q1 + Q2 + Q3 + Q4 + Q5 = Qtotal

Qtotal = 0.21636 kJ +4.008 kJ +5.0256 kJ +27.084 kJ.

qtotal = 36.607 kJ

The statement "Metallic behavior correlates with large atomic size and low ionization energy. Thus, metallic behavior increases down a group and decreases from left to right across a period" is true.

The statement is true because metallic behavior correlates with large atomic size and low ionization energy. So, as you go down a group, the atomic size and ionization energy decrease, resulting in increased metallic behavior. As a result, when going from left to right across a period, the atomic size decreases, and the ionization energy increases, resulting in a decrease in metallic behavior.

As a result, the metallic behavior increases down a group and decreases from left to right across a period.

Atoms are the smallest particles that made up matter.

The bond angles in SF₅⁺ are expected to be 90°, 120°, and 180°.

The correct option is E.

Bond angles refer to the angles between the bond linking the atoms of elements in a compound or ion.

The bond angles exist as a result of either electrical repulsion between the electrons in the bonds.

Cation

When naming a chemical compound, the cation is written first before anything else.

A typical ionic compound consists of two components - the cation and the anion. While the cation is positively charged in ion, the anion is negatively charged. The cation of a typical ionic compound is named first before the anion and the name often carries that of the element that composes it.

The name of the element that makes up the anion is modified by removing the last few characters ending the name and replacing it with the suffix 'ide'. For example, NaCl is named sodium chloride.

After 244 ml of soda is removed, there is 325 ml - 244 ml = 81 ml left in the can. This answer should be reported with the correct number of significant figures and proper units, which in this case would be 81 ml (3 significant figures).

When calculating the remaining amount of a substance after a portion has been removed, it is important to consider both the accuracy and units of the measurements involved. In this case, a can contains 325 ml of soda and 244 ml of soda has been removed. To find the remaining amount, we subtract the amount removed from the original amount: 325 ml - 244 ml = 81 ml. The answer should be reported with the correct number of significant figures, which reflects the level of accuracy of the measurements, and proper units, which in this case would be 81 ml (3 significant figures). It is important to use the correct number of significant figures and proper units when reporting the results of any calculation, as this helps to ensure the accuracy and consistency of the results, and makes it easier for others to understand and interpret the results.

No, the volume of water in a beaker is not an extensive property.

Extensive properties are those that depend on the amount or size of the substance being measured. In other words, they are properties that change with the quantity of the substance. Examples of extensive properties include mass, volume, and total energy.

In the given scenario, the volume of water in the beaker is 50 milliliters. This volume remains the same regardless of the quantity of water present. Whether it's 50 milliliters or 500 milliliters, the volume measurement does not change. Therefore, the volume of water in the beaker is an example of an intensive property.

Intensive properties are independent of the amount or size of the substance. They are characteristics that remain constant regardless of the quantity of the substance. Examples of intensive properties include temperature, density, and color.

It's important to note that the distinction between extensive and intensive properties depends on the specific property being considered. While volume is typically an extensive property for a bulk substance, in the case of a fixed volume of water in a beaker, it becomes an intensive property.

In summary, the volume of water in a beaker is not an extensive property but rather an intensive property because it does not change with the quantity of the substance.
