Which has more atoms: one mole of helium or one mole of lead?
Answer:
They're equal.
Explanation:
Giving an idea let's use the question:
How big would a box be that holds one mole of helium?This would depend on the temperature and pressure conditions that the helium gas is being stored under.
You see, gases have no fixed volume. They will expand when the temperature increases and/or the applied pressure decreases. On the other hand, the gas will contract when cooled or pressure is applied. So one mole of helium could occupy almost any volume, depending on how much you compress it or how cool you keep it.
However, if your helium gas is stored under standard temperature and pressure conditions (STP)(0 C and 101.3 kPa), then it would fill a box with a volume of 22.4 L. This volume is known as the standard molar volume and is the same for any gas at STP.
I will let you come up with a set of dimensions for a box that could satisfy this volume.

a sample of ozone gas occupies 225 ml at 1.00 atm and 0c if the volume of the gas is 625ml at 25c what is the pressure
To solve this problem, we can use the combined gas law formula, which is (P1 * V1) / T1 = (P2 * V2) / T2. Given the initial and final conditions of ozone gas, we need to find the pressure (P2) at 625 mL and 25°C.
Initial conditions:
P1 = 1.00 atm
V1 = 225 mL
T1 = 0°C + 273.15 = 273.15 K (convert to Kelvin)
Final conditions:
V2 = 625 mL
T2 = 25°C + 273.15 = 298.15 K (convert to Kelvin)
P2 = ? (This is the pressure we need to find)
Using the combined gas law formula, we get:
(1.00 atm * 225 mL) / 273.15 K = (P2 * 625 mL) / 298.15 K
Now, solve for P2:
P2 = (1.00 atm * 225 mL * 298.15 K) / (273.15 K * 625 mL)
P2 ≈ 0.659 atm
The pressure of the ozone gas at 625 mL and 25°C is approximately 0.659 atm.

mercury has the widest variation in surface temperatures between night and day of any planet in the solar system.
Mercury has the widest variation in surface temperatures between night and day of any planet in the solar system.
This statement is true. Mercury experiences the greatest temperature variation between night and day due to several factors. The main reasons are its proximity to the Sun, slow rotation, and lack of atmosphere.
During the daytime, temperatures on Mercury can reach up to 800°F (430°C) due to its close proximity to the Sun. This extreme temperature difference is due to the fact that Mercury's thin atmosphere is unable to regulate temperature and its slow rotation causes one side of the planet to be constantly facing the sun while the other is in perpetual darkness.
At night, temperatures can drop as low as -290°F (-180°C) because of its slow rotation and the lack of an atmosphere to retain heat. This results in the widest variation in surface temperatures between night and day of any planet in our solar system.

https://brainly.com/question/16117265
#SPJ11
Mercury indeed has the widest variation in surface temperatures between night and day of any planet in the solar system. This is primarily due to its thin atmosphere, which cannot effectively retain heat, leading to extreme temperature fluctuations.
Mercury, being the closest planet to the sun, experiences extreme variations in temperature between its day and night sides. During the day, when the sun is overhead, the surface temperature on Mercury can rise to a scorching 430°C (800°F), which is hot enough to melt lead. However, as Mercury rotates and the sun sets, the temperature drops drastically to as low as -180°C (-290°F) at night.
The main reason for this extreme temperature variation is that Mercury has no atmosphere to regulate its surface temperature. Unlike Earth, which has an atmosphere that helps to distribute heat around the planet, Mercury's surface is directly exposed to the sun's radiation. This means that when the sun is shining on Mercury's surface, it heats up quickly and intensely, causing the temperature to rise to extreme levels.
Overall, the lack of an atmosphere and Mercury's proximity to the sun are the main factors contributing to the extreme temperature variations on the planet.

ΔH will be equal to ΔE if the total number of moles of gas does not change during a chemical reaction (discounting any small volume change caused by liquids or solids).
This is based on the principle of the conservation of energy, which states that energy cannot be created or destroyed, only transferred or converted from one form to another. In a chemical reaction, energy can be transferred between the system (the reactants and products) and the surroundings (the environment outside the system).
The enthalpy change (ΔH) of a reaction is the amount of heat energy transferred between the system and surroundings at constant pressure. The internal energy change (ΔE) of a reaction is the amount of heat energy transferred between the system and surroundings at constant volume.
If the total number of moles of gas does not change during a chemical reaction, then there is no change in volume, and ΔH will be equal to ΔE. This is because the work done by the system on the surroundings (expansion work) is zero, and the heat transfer at constant volume is equal to the change in internal energy.

The procalamine solution provides approximately 74.7 grams of protein per day.
To decide the quantity of grams of protein gave by the procalamine arrangement, we really want to know the complete number of kilocalories (kcal) given by the arrangement each day and the extent of kcal that come from protein.
How much glycerin in the arrangement is 3% or 0.03. The kcal given by the glycerin can be determined as:
125 ml/h x 24 h/day = 3000 ml/day
3000 ml/day x 0.03 = 90 g/day
90 g/day x 4.3 kcal/gm = 387 kcal/day
Additionally, how much amino corrosive in the arrangement is 3%. The kcal given by the amino corrosive can be determined as:
125 ml/h x 24 h/day = 3000 ml/day
3000 ml/day x 0.03 = 90 g/day
90 g/day x 4 kcal/gm = 360 kcal/day
The absolute kcal given by the arrangement each day is:
387 kcal/day + 360 kcal/day = 747 kcal/day
Accepting that 10% of the complete kcal given by the arrangement come from protein, the quantity of grams of protein given by the arrangement each day is:
747 kcal/day x 0.10 = 74.7 g/day
Thusly, the procalamine arrangement gives roughly 74.7 grams of protein each day.

23 grams of water at 95°C can lose a maximum of 8883.64 Joules of heat before freezing completely.
To answer your question, we need to calculate the heat loss required to lower the temperature of 23 grams of water from 95 degrees Celsius to 0 degrees Celsius, which is the freezing point of water. The specific heat capacity of water is 4.184 Joules per gram per degree Celsius.
So, the initial energy of the water is:
E1 = m x c x ΔT
E1 = 23 g x 4.184 J/g°C x (95°C - 0°C)
E1 = 8883.64 J
Where E1 is the initial energy of the water, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature.
The final energy of the water at 0°C is:
E2 = m x c x ΔT
E2 = 23 g x 4.184 J/g°C x (0°C - 0°C)
E2 = 0 J
So, the maximum amount of heat in joules that 23 grams of water at 95°C can lose before freezing completely is:

Miltown is 15c (59f) in the spring. it What is the source for most of the energy that causes this temperature?
The source for most of the energy that causes the temperature of Miltown to be 15°C (59°F) in the spring is the sun.
How does the sun's energy keep the temperature of Miltown to be 15°C (59°F) in the spring?The sun's energy is responsible for heating the Earth's surface, which in turn heats the surrounding air through convection. The amount of energy that reaches the Earth's surface depends on factors such as the angle of incidence and atmospheric conditions, but the sun is ultimately the primary source of energy that drives Earth's weather patterns and temperature fluctuations. Thus, the sun plays a crucial role in determining the temperature and climate of Miltown, as well as the rest of the planet.

in order to calculate the ph of a salt solution generated from a weak acid and a weak base by using a single ice chart, what must be true?
In order to calculate the pH of a salt solution generated from a weak acid and a weak base using a single ice chart, a few things must be true.
Firstly, the weak acid and weak base must react to form a salt and water. This is important because the salt will affect the pH of the solution. Secondly, the acid and base must be of equal strength.
If one is stronger than the other, the resulting solution will either be acidic or basic, depending on which is stronger. Finally, the initial concentrations of the acid and base must be known,
as well as the equilibrium constant of the acid-base reaction. With this information, the single ice chart can be used to determine the concentrations of all species in the solution at equilibrium, which can then be used to calculate the pH of the solution.

one mole of fluorine reacts with two mole of hot concentrated potassium hydroxide. The products formed are KF H20, and O2. The molar ratio of KF, H20 and 02 is
KF H20 and O2 are the byproducts. The molar ratios of KF, H₂0, and O₂ are 2: 1: 0.5.
What is the difference between molars and moles?The molar mass of a chemical compound is defined as the sample's weight divided by the total amount of material in the that test, expressed in moles. The distinction between mole and mole ratio mass means that the sheer quantity of molecules needed to create one mole of any material is fixed.
How is molar determined?
The molar mass is calculated by dividing the mass of a specified chemical element or active ingredient (g) by the quantity of the substance (mol). A compound's molar mass can be determined through the addition of standard atoms (in g/mol) of its constituent atoms.
