2. The ions of lead also have 82 protons.

The correct answer to the question is Option D. Neutral atoms of lead must have 82 protons. Ions must have 82 protons, as well.

Lead, Pb is a metal with an atomic number (i.e proton number) of 82

Metals can only form ions by losing their valence electron(s)

The average atomic mass of her sample is 114.54 amu

Let the 1st isotope be A

D. It will be more than 26 °C as water needs relatively higher energy than sand to raise its temperature.

Answers

hi have a nice day

will be less than 26 °C as water has a relatively higher specific heat than sand.

Explanation:

The specific heat of a substance is the amount of heat energy absorbed by one unit of mass of the substance when its temperature increases one unit.

From that, you can derive the equation for the specific heat of a substance:

specific heat = heat / (mass × ΔT)

Thus, assuming that all the heat provided by the lamp to both samples is the same and, as given, the amount (mass) of both samples is also the same, you have that the specific heat of the samples will be:

specific heat = constant / ΔT

So, specific heat and ΔT are inversely related.

It is known that water has a higher specific heat than sand (that is why the sand on the shore of a beach is, during the day, hotter than the water and your feet get burned when you walk on a sandy beach on a sunny day

3 moles of nitrogen and 5 moles of hydrogen react to form ammonia. Use the balanced equation below to determine which is the limiting reactant.

N2 + 3H2 --> 2NH3

Answers

Answer:

H₂ is the limiting reactant

Explanation:

Balanced equations demonstrate the ratios of all reactants and products in terms of the number of atoms/molecules or moles;

In the given reaction:

1 mol of N₂ reacts with 3 mol of H₂ to produce 2 mol of NH₃

So the ratio of N₂ to H₂ to NH₃ will be 1:3:2

If we have 3 moles of N₂, we can apply the ratio to find that it will react with 9 moles of H₂ (3× the moles of N₂) to produce 6 moles of NH₃ (2× the moles of N₂);

Similarly, if we have 5 moles of H₂, then applying the ratio, we find that ⁵/₃ or 1.66... moles of N₂ (¹/₃× the moles of H₂) react with 5 moles of H₂ to produce ¹⁰/₃ or 3.33... moles of NH₃ (²/₃× the moles of H₂);

In order for all of the 3 moles of N₂ to react, it would require 6 moles of H₂;

There is only 5 moles of H₂ available, meaning there will be an excess of N₂;

5 moles of H₂ will react with 1.66... moles of the N₂, leaving 1.33... or ⁴/₃ moles of N₂ unreacted;

If the N₂ is in excess, then the H₂ is limited (i.e. the limiting reactant)

A 33.4−L volume of methane gas is heated from 22°C to 66°C at constant pressure. What is the final volume of the gas?

Answers

Answer:

38.38 L (3 d.p.)

Explanation:

In response to questions addressing the expansion of gas via heating, Charles's Law should be considered. Charles's Law is an experimental gas law explaining the tendency of gases to expand when heated.

The law states that the volume ([tex]V[/tex])  of a gas is directly proportional to its temperature ([tex]T[/tex]) given that the pressure ([tex]P[/tex]) and the amount of gas ([tex]N_{A}[/tex]) are constant.

[tex]\displaystyle\frac{V}{T} \ = \ k \ \ \ \ \ \ \ or \ \ \ \ \ \ \ V \ = \ kT[/tex], where k is a proportionality constant.

*Note that when substituting temperature into the equation, the temperature must be in terms of the Kelvin scale and not in degrees Celsius. The relation between the Kelvin scale and the Celsius scale is  [tex]\mathrm{K} \ = \ ^{\circ}\mathrm{C} \ + \ 273[/tex].

Charles's law can be used to compare changing conditions of a particular gas. Let  [tex]V_{1}[/tex]  and  [tex]T_{1}[/tex]  be the initial volume and temperature for the gas, while  [tex]V_{2}[/tex]  and  [tex]T_{2}[/tex]  be the final volume and temperature. The mathematical relationship of Charles's law becomes:

[tex]\displaystyle\frac{V_{1}}{T_{1}} \ = \ \displaystyle\frac{V_{2}}{T_{2}}[/tex].

In accordance with the question,

[tex]V_{1} \ = \ 33.4 \ \mathrm{L}, \ T_{1} \ = \ (22 \ + \ 273) \ \mathrm{K} \ = \ 295 \mathrm{K}, \ T_{2} \ = \ (66 \ + \ 273) \ \mathrm{K} \ = \ 339 \ \mathrm{K}[/tex]

while  [tex]V_{2}[/tex]  is the final volume of the gas that we would like to find. Therefore,

[tex]V_{2} \ = \ \displaystyle\frac{V_{1} \ \times \ T_{2}}{T_{1}} \\ \\ V_{2} \ = \ \displaystyle\frac{33.4 \ \mathrm{L} \ \times \ 339 \ \mathrm{K}}{295 \ \mathrm{K}} \\ \\ V_{2} \ = \ 38.38 \ \mathrm{L}[/tex].

The Lewis structure is the way of expressing the covalent bonding in molecules. The covalent bond formation takes place by the sharing of electrons in a molecule.

What is Lewis structure?

In Lewis dot structures or simply the Lewis structures, the dots are used to represent the electrons. They provide a picture of bonding in molecules in terms of the shared pair of electrons and the octet rule.

The concept of covalent bond is introduced by the scientist G.N Lewis. According to him, the atoms achieve stable octet when they are linked with each other by sharing of one more pairs of electrons. The covalent bonding occurs between the atoms which do not differ much in their electronegativity.

The Lewis structure of CaBr₂ is denoted below. Here two bromine atoms acquires a stable electronic configuration by sharing electrons. There are two single bonds between them.

The importance of wearing a seatbelt while riding in the car can best be explained using:

A) Newton's First Law (Law of Inertia)

B) Newton's Second Law (F=ma)

C) Newton's Third Law (Action-Reaction)

D none of the above

Answers

Explanation:

this is a chemistry question ???

anyway, it is clearly A, as seatbelts try to counteract the inertia a moving body (our bodies riding in a car) has, when the environment (the car) of this body is suddenly coming to a stop.

this inertia would otherwise try to move the body still forward resulting in a headfirst crash into and often through the windshield. which causes much more damage to the body than the bruises caused by the pressure of the seatbelts against the body counteracting the body's inertia.

but also clearly, all 3 laws play a role.

the force with which the moving body has to deal when smashing into the windshield and potentially then other objects outside the car is described by the second law.

and for any action (crash) there are corresponding reactions (like the conversion of the crash energy into some absorbing reaction : damaged soft and hard tissue in the human body, crumbled car bodies,...).

Which of the following statements are true about energy and bonds?
Check all that apply.
A. The formation of bonds does not absorb or release energy.
B. When bonds are formed, energy is released.
C. Energy is absorbed to break bonds.
D. Breaking bonds does not absorb or release energy.

Answers

Answer:

A. Energy is necessary for bond formation.

C. Breaking bonds takes energy.

D. When bonds are formed, energy is released.

Energy is always required for bond formation because when a chemical reaction occurs, either molecular bonds are broken or other bonds are formed to make different molecules. Energy is released during bond formation and is an exothermic process because bond formation represents a stable configuration and the energy lost is released as heat energy that makes it more stable. Breaking bonds takes energy and is an endothermic reaction because energy is absorbed to break bonds.

The discrepancy between results given by the van der Waals equation and the ideal gas law will increase as:

Answers

This question is recalling the behavior of real gases in contrast to ideal gases, defined by the van der Waals equation and the ideal gas law respectively, and a reason behind the increasing discrepancy is required.

In such a way, we can start by considering the attached picture in which the choices are shown and clearly, the answer is "as the polarity of the molecules increase".

The aforementioned can be explained with the concept of intermolecular forces, because ideal gas theory states that ideal gas molecules do not interact one to another, and, as the polarity of the molecules increase, these intermolecular forces increase their frequency and strength, and will lead to the formation of associations, which fail to be numerically modelled by simple equations of state such as van der Waals, Redlich-Kwong, Peng-Robinson, etc,.

These associations are, of course, thoroughly neglected by the ideal gas law whereas the ones included in the van der Waals equation, which are not the most reliable, merely attempt to approach this phenomenon, which cause the mentioned discrepancy. As an additional data, robust equations of state, such as CPA (cubic plus association) are able to provide reliable results when working with highly polar gases but turn out really tough to work with due to its mathematical complexity.
