_____has particles with the greatest average kinetic energy
a
Ice water
b
Hot water
c
Warm water
d
Room temperature water
Answer:
c warm water
Explanation:
Kinetic energy is related to temperature. The molecules in a glass of warm water have more kinetic energy (they move faster – see Racing Molecules) than the molecules in a glass of cold water. The temperature of a substance is the average* amount of kinetic energy its molecules have.
Answer:
hot water
Explanation:
explain how to find the mass of water. show your calculations as well
Answer:
You can find the mass of water by multiplying the density of water by its volume.
mass = Density x volume
Explanation:
It is very easy to find the mass of water once you know the formula of density. "Density" refers to mass per unit volume.
Density (ρ) = [tex]\frac{mass}{volume}[/tex]
Therefore, mass = ρ x volume
The density of water is 1 kg/L.
For example, if the volume of water is 500 ml, then you can get its mass by multiplying 500 ml by 1 kg/L.
Let's convert 500 ml to Liter first.
500 ml x [tex]\frac{1 L}{1,000 ml}[/tex] = 0.5 L
Now, let's compute.
mass = ρ x volume
mass = 1 kg/L x 0.5L
mass = 0.5 kg
The mass of a 500-ml water is 0.5 kg.

The density of H2O2 is 1.407 g/mL, and the density of O2 is 1.428 g/L. How many liters of O2 can be made from 55 mL H2O2
Explanation:
mass H2O2 = 55 mL(1.407 g/mL) = 80.85 g
molar mass H2O2 = 2(1.01 g/mol) + 2(16.00 g/mol) = 34.02 g/mol
moles H2O2 = 80.85 g/34.02 g/mol = 2.377 moles H2O2
For each mole of H2O2 you obtain 0.5 mole of O2 (see the equation).
moles O2 = 2.377 moles H2O2 (1 mole O2)/(2 moles H2O2) = 1.188 moles O2
Now, you need the temperature. If you are at STP (273 K, and 1.00 atm) then 1 mole of an ideal gas at STP has a volume of 22.4 L. Without temperature you are not really able to continue. I will assume you are at STP.
Volume O2 = 1.188 moles O2(22.4 L/mole) = 0.0530 L of O2.
which is 53 mL.

What is the total pressure in units of kPa in a 7.85 L container that contains 4.45 moles of N2 and 2.45 moles of O2 at a temperature of 307 K?
Answer:
Total pressure = 22.15 atm
Explanation:
Given data:
Total pressure = ?
Volume of container = 7.85 L
Number of moles of N₂ = 4.45 mol
Number of moles of O₂ = 2.45 mol
Temperature = 307 K
Solution:
Pressure of N₂:
PV = nRT
P = nRT/V
P = 4.45 mol ×0.0821 atm.L/mol.K ×307K / 7.85L
P = 112.16 atm.L/7.85 L
P = 14.28 atm
Pressure of O₂:
PV = nRT
P = nRT/V
P = 2.45 mol ×0.0821 atm.L/mol.K ×307K / 7.85L
P = 61.75 atm.L/7.85 L
P = 7.87 atm
Total pressure = P(N₂) + P(O₂)
Total pressure = P( 14.28 atm) + P( 7.87 atm)
Total pressure = 22.15 atm

What is different about the atomic structure of the oxygen isotopes?
Answer:
Each isotope of oxygen contains 8 protons, but differs in the number of neutrons. An isotope number is a shorthand representation of its mass. Because protons and neutrons are roughly equal in mass, an isotope's number is equal to the sum of its protons and neutrons.
Explanation:
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

Name the three stress forces that cause changes in Earths crust. Explain how each type of force affects rock.Identify the type of fault that each force produces. This is science i couldnt find a science thing
Answer:
Shear
Tension
Compression
Explanation:
The 3 stress forces are;
-shear
-tension
-compression
1) Shear is the stress force that pushes back a mass of rock in two opposite directions which in turn will produce strike - slip faults.
2) Tension is the stress force that pulls on the crust thereby stretching in a manner that it becomes thinner at its middle which in turn will produce normal faults.
3) Compression is the stress force that makes rocks squeeze until they fold or break and this will in turn produce reverse faults.
if an unknown gas has one third the root mean squarevspeed of H2 at 300 K, what is the molar mass of the gas?
The molar mass of the gas : 18 x 10⁻³ kg/mol
Further explanationGiven
An unknown gas has one third the root mean square speed of H2 at 300 K
Required
the molar mass of the gas
Solution
Average velocities of gases can be expressed as root-mean-square (V rms)
[tex]\large {\boxed {\bold {v_ {rms} = \sqrt {\dfrac {3RT} {Mm}}}}[/tex]
T = temperature, Mm = molar mass of the gas particles , kg/mol
R = gas constant 8,314 J / mol K
v rms An unknown gas = 1/3 v rms H₂
v rms H₂ :
[tex]\tt v_{rms}=\sqrt{\dfrac{3\times 8.314\times 300}{2.10^{-3}} }\\\\v_{rms}=1934.22[/tex]
V rms of unknown gas =
[tex]\tt \dfrac{1}{3}\times 1934.22=644.74[/tex]
[tex]\tt 644.74^2=\dfrac{3\times 8.314\times 300}{M_{gas}}\\\\M_{gas}=18\times 10^{-3}~kg/mol[/tex]

________ is the enthalpy change when 1 mole of a substance is formed from its elements under standard conditions.
A. ΔHθc
B. ΔHθn
C. ΔHθf
D. ΔHθa
The correct answer is C. ΔHθf
We define the standard enthalpy of formation as the enthalpy change when one mole of a substance is formed from its elements under standard conditions. The standard conditions are 1 atm pressure, 273 K temperature and 1 M concentration.
The standard enthalpy of formation is denoted using the symbol ΔHθf.
Hence, ΔHθf is the enthalpy change when 1 mole of a substance is formed from its elements under standard conditions.

What types of radiation cause the parent isotope to change into a different element?
Answer:
Beta decay is most common in elements with a high neutron to proton ratio. Gamma decay follows the form: In gamma emission, neither the atomic number or the mass number is changed. A high energy gamma ray is given off when the parent isotope falls into a lower energy state.

Dr. Moore and his team have learned from GPS data that two continents with an ocean between them have been moving toward each other. Some students living on the coast of one of these continents don’t understand what is happening and they are worried that the continents will run into each other. How could Dr. Moore explain to them what is happening?
Answer:
Dr. Moore can explain that it is continental drift.
Explanation:
continental drift is the phenomenon due to which all the continents are moving towards each other, due to this continental drift stundents afraidthat some day these continents will collide leading to catastrophe.
But this is not gonna happen in a snap, this needs a lot of time, this will take hundreds of years and even more. So there is nothing to be afraid of till then humans will find some or the other way to manage this. Plus as I said this process is very slow so there are very less chances that this could lead us to any kind of chaos or anhilation.

Explain the horizontal periodic trend
Answer:
Trends on the Periodic Table have a vertical component and a horizontal component. Vertical trend: as more “shells” are added to the electron cloud, it expands. Horizontal trend: if atoms have the same number of “shells”, atoms with more protons will draw the electron cloud in tighter.
