When a gas is heated in a sealed container, the gas particles move faster and hit the sides of the container with more force leading to an increase in the pressure of the gas.
An increase in the temperature of a gas increases the collision rate of the molecules of the gas according to the kinetic theory.
With increased kinetic energy, the molecules of the gases collide more frequently with each other and the walls of the container.
The collision creates an increase in the magnitude of pressure inside the container.

Rubia was given a type of inclined plane called a ramp in her science class. Her teacher told her that the ramp should have a mechanical advantage of 3.
Rubia pulled a block up the ramp, but afterward she calculated that the mechanical advantage of the ramp was 2.8 instead of 3. Her teacher said she did not make a mistake. What did Rubia calculate?
A.
the actual operating power of the ramp
B.
the actual mechanical advantage of the ramp
C.
the ideal mechanical advantage of the ramp
D.
the ideal operating power of the ramp
Answer: B. The actual mechanical advantage of the ramp.
Explanation:
The professor saying that the ramp SHOULD have a mechanical advantage of 3 indicates that that would be the ideal mechanical advantage. Since Rubia calculated it to be 2.8, that means that it is the acutal mechanical advantage. The actual advantage will be reduced from the ieal due to things like friction.

How does VSEPR theory describe the double bonds between the central carbon atom and each oxygen atom of Co2?
The double bonds in CO2 are counted as single regions of electron density.
The valence shell electron pair repulsion theory VSEPR is a description of the shape of molecules based on the number of electron pairs that surround the central atom in the molecule. Double bonds are counted as a single region of electron density.
Hence, the two double bonds in CO2 are counted as two regions of electron density around the central carbon atom. Hence, the molecule is liner at a bond angle of 180 degrees.

~AH1807A scientist was in the field when he saw a mineral sample. He wanted to determine the relative hardness of the mineral, so he conducted scratch tests. He summarized his results in a table. A 2 column table with 4 rows. The first column is labeled Mineral with known hardness with entries: Chalcopyrite, pyrite, Orthoclase, Quartz. Second column is labeled Was a scratch produced? with entries: Yes, Yes, Yes, No. What conclusion can you make about the hardness of the mineral?.
The mineral hardness depends on its resistance to being scratched. Mohs scale is used to determine the hardness of an unknown mineral. The unknown mineral is harder than Orthoclase, but not harder than Quartz.
-------------------------
The hardness of a mineral is its resistance to being scratched or marked on the surface by another material.
Several elements are used to test the hardness of a mineral, like another mineral of known hardness.
Many different scales can be used to identify the mineral. However, the most commonly used is the Mohs scale.
Let us say that you have two minerals. You already know which mineral is one of them and its hardness.
If the unknown mineral scratches the known mineral, means that the first one is harder than the second one.But if the unknown mineral does not get to scratch the known one, it means they are equally hard, or the known mineral is harder than the unknown one.In the exposed example, the table must be as follows
Mineral Was a scratch produced?
Chalcopyrite YES
pyrite YES
Orthoclase YES
Quartz NO
Quartz is the hardest of these minerals. Its hardness level is 7 according to the Mohs scale.
Because scratches were produced using Chalcopyrite, Pyrite, and Orthoclase, we can assume that the unknown mineral is harder than these three ones.
However, no scratch was produced using quartz, suggesting that the unknown mineral is between orthoclase and quartz in the Mohs scale.
The unknown mineral is harder than Orthoclase, but not harder than Quartz. It is between 6 and 7 hardness levels.

When 25.0 g of NaCl is added to 175 g of water, the mass percent (m/m) NaCl is ________. 7.00% 8.00% 12.5% 25.6% 14.3%
Answer:
12.5%
Explanation:
percent blurf = quantity of blurftotal quantity×100quantity of blurftotal quantity×100
So for percent by mass, both quantities are expressed as mass, and it’s the mass of NaCl divided by the total mass of the solution, then times 100%
mass % NaCl = 25 g/175g×100
mass %NaCl = 14.3%

Why does liquid move like it does when heated on the right side?
Answer:Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids.
Explanation:Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.

A student pours ammonium nitrate into a container of room temperature water. The student stirs the mixture with a stirring rod and then feels the outside of the container, which is cold to the touch. Which material is part of the system that absorbed heat?
the water
the air
the stirring rod
the container
The material that absorbs the heat of the system is water owing to its high specific heat capacity.
The specific heat capacity of a substance refers to the amount of heat that is capable of increasing the temperature of 1 Kg of a body by 1 K. The higher the specific heat capacity, the more the amount of heat that the body can absorb without temperature change.
The material that absorbs the heat of the system is water because water has a higher specific heat capacity than all the other materials present.

The material which is part of the system that absorbed heat is; The water.
Discussion:
According to the question;
Water was initially at room temperature.We know by convention, ammonium nitrate is a cold substance.In essence, the heat liberated from the system must have been absorbed by the water so that the outside of the container after mixing becomes cold.
This is so because water has a high specific heat capacity.

A chemist wants to extract the gold from 54.9 g of AuCl3*2H20 *gold(III) chloride dyhydrate) by electrolysis of an aqueous solution. What mass of gold could be obtained from this sample? Answer in units of g
From the information provided in the question, the mass of gold that can be obtained from this sample is 31.5 g of Au.
Given that the reduction of gold III occurs thus;
Au^3+(aq) + 3e ------> Au(s)
Number of moles of gold(III) chloride dihydrate = mass/molar mass = 54.9 g /339.35 g/mol = 0.16 moles
Number of moles of Au^3+ in AuCl3.2H20 = 0.16 moles
Now;
1 mole of Au has a mass of 197 g/mol
0.16 moles of Au has a mass of 0.16 moles × 197 g/mol/1 mole
= 31.5 g of Au.
The mass of gold that can be obtained from this sample is 31.5 g of Au.
