Learn how factors, such as exposure to the atmosphere, the composition of rock and climate affect the rate of weathering. Weathering is the mechanical or chemical process by which rocks are broken down. The weathering that happens to rocks can be understood by relating it to the digestion of a chocolate chip cookie
One of the factors that affects the rate of weathering is exposure to the atmosphere. ... Another factor that affects the rate of weathering is the composition of rock. Rocks are composed of minerals, which are solid substances found within rocks that have their own distinct chemical composition.

a sample of carbon dioxide gas occupies a volume of 20 L at standard temperature and pressure (STP). what will be the volume of a sample of argon gas that has the same number of moles and but tripled the absolute temperature?
Volume of Argon = 59.972 L
Further explanationIn general, the gas equation can be written
[tex]\large {\boxed {\bold {PV = nRT}}}[/tex]
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08206 L.atm / mol K
T = temperature, Kelvin
At STP(0 C, 1 atm), 1 mol gas= 22.4 L
so for 20 L
[tex]\tt \dfrac{20}{22.4}=0.893[/tex]
For Argon
P = 1 atm
T = 273 K x 3 =819 K (tripled)
n = 0.893 (the same number of moles)
R = 0.082 L/atm.mol K
[tex]\tt V=\dfrac{nRT}{P}=\dfrac{0.893\times 0.082\times 819}{1}=59.972~L[/tex]
Most plastics are made from oil or natural gas. One step in making plastics from these resources is called cracking. Cracking is a process that breaks down bigger molecules into smaller ones. In one cracking reaction, ethane breaks down to become ethylene and hydrogen. During this process, thermal energy is absorbed from the surroundings and converted to chemical energy.

The reactants in a chemical equation have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms. In order to follow the conservation of matter, the products of the chemical equation will have
Answer:
The same amount of atoms (3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms).
Explanation:
According to the law of conservation of mass, when a chemical reaction takes place there is no synthesis or degradation of matter, that is, matter can be neither created nor destroyed. It can only be transformed.
Therefore, in a chemical reaction the atoms are conserved. That means that the elements that in definite proportions are forming a compound, will reorganize to form new compounds, and the amount and type of atoms of the products will be the same as the reactants.
In summary, if the reactants in a chemical equation have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms, the products of the chemical equation will have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms as well.

a cube has a length of 1.02 cm and a mass of .001012 kg what is its density
Answer:
d = 9.5× 10⁻⁴ Kg/cm³
Explanation:
Given data:
Length of cube = 1.02 cm
Mass of cube = 0.001012 Kg
Density of cube = ?
Solution:
The length , height and width of cube is always same. Thus the volume of cube is,
Volume = length × height× width
Volume = 1.02 cm × 1.02 cm × 1.02 cm
Volume = 1.06 cm³
Density of cube:
d = 0.001012 Kg /1.06 cm³
d = 9.5× 10⁻⁴ Kg/cm³
Two sphericle objects have masses of 8000 KG and 1500 KG their centers are separated by a distance of 1.5 M find the gravitational attraction between them
if I am correct I think its I'm am not 100 percent sure but I think this should be the answer
The gravitational force of attraction between them is 3.56 * 10⁻⁴ N
Using the formula of gravitational attraction
F = G*M1M2/d²
where G = 6.67 * 10⁻¹¹ Nm²Kg⁻²
M1 = 8000Kg
M2 = 1500 Kg
F = 6.67 * 10⁻¹¹ * 8000 * 1500 / (1.5)²
F = 3.56 * 10⁻⁴ N
The gravitational force of attraction between them is 3.56 * 10⁻⁴ N

How many moles of cesium carbonate will be produced when 5.34 moles of cesium reacts with iron (III) carbonate? (You must write and balance the formula equation!)
Answer:
2.67 moles of cesium carbonate (Cs2CO3).
Explanation:
We'll begin by writing the equation for the reaction. This is illustrated below:
Cs + Fe2(CO3)3 —> Cs2CO3 + Fe
The above equation can be balance as follow:
There are 2 atoms of Fe on the left side and 1 atom on the right side. It can be balance by putting 2 in front of Fe as shown below:
Cs + Fe2(CO3)3 —> Cs2CO3 + 2Fe
There are 3 atoms of C on the left side and 1 atom on the right side. It can be balance by 3 in front of Cs2CO3 as shown below:
Cs + Fe2(CO3)3 —> 3Cs2CO3 + 2Fe
There are 6 atoms of Cs on the right side and 1 atom on the left. It can be balance by putting 6 in front of Cs as shown below:
6Cs + Fe2(CO3)3 —> 3Cs2CO3 + 2Fe
Thus, the equation is balanced.
From the balanced equation above,
6 moles of Cs reacted with 1 mole of Fe2(CO3)3 to produce 3 moles of Cs2CO3.
Finally, we shall determine the moles of cesium carbonate (Cs2CO3) produced by the reaction of 5.34 moles of cesium (Cs). This can be obtained as follow:
From the balanced equation above,
6 moles of Cs reacted to produce 3 moles of Cs2CO3.
Therefore,
5.34 moles of Cs will react to produce = (5.34 × 3)/6 = 2.67 moles of Cs2CO3.
Thus, 2.67 moles of cesium carbonate (Cs2CO3) were produced from the reaction.

52 atm
Answer:
The answer is 25 atmExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
From the question we have

if you start with a substance as a solid what will happen to the molecules as you add thermal energy (heat)?
Answer: One change of state happens when you add energy to the substance. This change of state is called melting. By adding energy to the molecules in a solid the molecules begin to move quicker and can break away from the other molecules.

If I place a balloon in my fridge that initially has a pressure of 1.02 atm and a
temperature of 11.2 °C, what will be the pressure (in atm) of the balloon when it is
fully cooled to 4.00°C by my refrigerator?
Answer:
P₂ = 0.99 atm
Explanation:
Given data:
Initial pressure = 1.02 atm
Initial temperature = 11.2°C
Final pressure = ?
Final temperature = 4.00°C
Solution:
Initial temperature = 11.2°C (11.2+273 = 284.2 K)
Final temperature = 4.00°C (4.00+273 = 277 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1.02 atm / 284.2 K = P₂/277 K
P₂ = 1.02 atm × 277 K / 284.2 K
P₂ = 282.54 atm. K /293 K
P₂ = 0.99 atm
