Yes, igneous rock become sedimentary rock through a process called sedimentation.
The sedimentary rock formed in the process above arises from sediment that was compacted and cemented. When igneous rock is lifted up by plate motion toward Rhombus’s surface, it become exposed to energy from Rhombus’s sun. Therefore, wind and water can move and breakdown the igneous rock into sediment. This process here, the sedimentary rock could have been igneous rock.In sedimentation, An igneous rock is broken down or crushed into little piece of rock called sediment, the sediment is then packed together as a result of othe rocks or strong forces, that form together to make a Sedimentary rock.
Conclusively, The process of erosion, heat and depositing rock grains which can also be known as sedimentation can alter or change igneous rock into sedimentary rock.

Give an example of a system in which people use steam for a mechanical advantage.
Answer:
Turbines.
Explanation:
Hello,
In this case, we define steam as high-energy vapor water, which has the capacity to be cooled to release energy to a system. For instance, turbines, use overheated steam to produce energy, by feeding the steam to the turbine's rotor blades in order to make the rotate and generate work. As a consequence of the rotation, the steam loses energy, for which it goes out from the turbine at low both temperature a pressure, even do, in some cases it could go out liquid so a condensation may occur.
Regards.
Answer:
Steam turbines

A sample of gas at 25 C has a volume of 11 L and exerts a pressure of 0.868 atm. How many moles of gas are in the sample?
0.39 mol
3.9 mol
9.3 mol
87 mol
Answer:
0.39 moles of gas are in the sample
Explanation:
An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:
P*V = n*R*T
where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas.
In this case:
P= 0.868 atmV= 11 Ln= ?R= 0.082 [tex]\frac{atm*L}{mol*K}[/tex]T=25 C= 298 KReplacing:
0.868 atm*11 L= n*0.082 [tex]\frac{atm*L}{mol*K}[/tex] *298 K
Solving:
[tex]n=\frac{0.868 atm*11 L}{0.082 \frac{atm*L}{mol*K} *298 K}[/tex]
n= 0.39 moles
0.39 moles of gas are in the sample

When 100.g Mg3N2 reacts with 75.0 g H2O, 15.0 g of NH3 is formed. What is the % yield?
Answer:
% yield = 44.5 %
Explanation:
Step 1: Data given
Mass of Mg3N2 = 100.0 grams
Mass of H2O = 75.0 grams
Mass of NH3 = 15.0 grams
Molar mass of Mg3N2 = 100.95 g/mol
Molar mass of H2O = 18.02 g/mol
Molar mass of NH3 = 17.03 g/mol
Step 2: The balanced equation
Mg3N2 + 3H2O → 3MgO + 2NH3
Step 3: Calculate moles
Moles = mass / molar mass
Moles Mg3N2 = 100 grams / 100.95 g/mol
Moles Mg3N2 = 0.99 moles
Moles H2O = 75.0 grams / 18.02 g/mol
Moles H2O = 4.16 moles
Moles NH3 = 15.0 grams / 17.03 g/mol
Moles NH3 = 0.88 moles
Step 4: Calculate the limiting reactant
For 1 mol Mg3N2 we need 3 moles H2O to produce 3 moles MgO and 2 moles NH3
Mg3N2 is the limiting reactant. It will completely be consumed (0.99 moles)
H2O is in excess. There will react 3*0.99 = 2.97 moles
There will be produced 2*0.99 = 1.98 moles of NH3
Step 5: calculate mass of NH3
Mass of NH3 = moles NH3 * molar mass NH3
Mass NH3 = 1.98 moles * 17.03 g/mol
Mass of NH3 = 33.7 grams
Step 6: Calculate the % yield
%yield = (actual yield/ theoretical yield) * 100 %
% yield = (15.0 grams / 33.7) * 100 %
% yield = 44.5 %
The percentage yield of ammonia in the given reaction has been 44.44%.
The balanced chemical reaction can be:
[tex]\rm Mg_3N_2\;+\;3\;H_2O\;\rightarrow\;3\;MgO\;+\;2\;NH_3[/tex]
The moles can be given as:
Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]
Moles of [tex]\rm Mg_3N_2[/tex] = [tex]\rm \dfrac{100}{100.95}[/tex] molMoles of [tex]\rm Mg_3N_2[/tex] = 0.99 mol
Moles of [tex]\rm H_2O[/tex] = [tex]\rm \dfrac{75}{18.02}[/tex]Moles of [tex]\rm H_2O[/tex] = 4.16 mol
Moles of [tex]\rm NH_3[/tex] = [tex]\rm \dfrac{15}{17.03}[/tex]Moles of [tex]\rm NH_3[/tex] = 0.88 mol
The limiting reactant can be:
From the balanced equation for 3 moles of water, there has been 1 mole of magnesium nitrite. So, for 4.16 moles of water, there will be 1.38 moles of [tex]\rm Mg_3N_2[/tex]. Since the amount of [tex]\rm Mg_3N_2[/tex] has been completely consumed in the reaction, [tex]\rm Mg_3N_2[/tex] has been the limiting reactant.
So, the moles of ammonia produced =
1 moles [tex]\rm Mg_3N_2[/tex] = 2 moles ammonia.
0.99 moles [tex]\rm Mg_3N_2[/tex] = 0.99 [tex]\times[/tex] 2 moles [tex]\rm NH_3[/tex]
0.99 moles [tex]\rm Mg_3N_2[/tex] = 1.98 moles of ammonia.
The theoretical yield of ammonia = 1.98 moles
The actual yield of ammonia = 0.88 mol.
% Yield of Ammonia = [tex]\rm \dfrac{Actual\;yield}{Theoretical\;yield}\;\times\;100[/tex]
% Yield of Ammonia = [tex]\rm \dfrac{0.88}{1.98}\;\times\;100[/tex]
% Yield of Ammonia = 44.44 %

Hello,
In this case, we define molarity as shown below:
[tex]M=\frac{N_{solute}}{V_{solution}}[/tex]
Whereas we have the moles of the solute and the volume of the solution in litres, in such a way, for finding the moles we solve for it as shown below:
[tex]N_{solute}=M*V_{solution}[/tex]
[tex]N_{solute}=0.415\frac{mol}{L} *16.0mL*\frac{1L}{1000mL}\\ \\N_{solute}=6.64x10^{-3}mol[/tex]
Best regards.
Answer:
0.00664 moles of solute are needed to prepare the solution.
Explanation:
Molarity is a unit of concentration based on the volume of a solution and is defined as the number of moles of solute per liter of solution. In other words, molarity is defined as the number of moles of solute that are dissolved in a given volume and is determined by the following expression:
[tex]Molarity (M)=\frac{number of moles of solute}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
In this case:
Molarity= 0.415 Mnumber of moles of solute= ?volume= 16 mL= 0.016 L (being 1 L= 1000 mL)Replacing:
[tex]0.415 M=\frac{number of moles of solute}{0.016 L}[/tex]
Solving:
number of moles of solute= 0.00664
0.00664 moles of solute are needed to prepare the solution.
A gas at 80 kPa occupies a volume of 5 mL. What volume will the gas occupy at 70 kPa
Answer:
Volume will the gas occupy at [tex]70[/tex] kPa [tex]= 5.71[/tex]
Explanation:
As per the gas law
[tex]P_1V_1 = P_2V_2[/tex]
Here
[tex]P_1 =[/tex] initial pressure of the gas
[tex]P_2[/tex] = final pressure of the gas
[tex]V_1 =[/tex] Initial volume of the gas
[tex]V_2[/tex] = the final volume of the gas
here,
[tex]P_1 = 80[/tex] kPa
[tex]V_1 = 5[/tex] mL
[tex]P_2 = 70[/tex]
Substituting the given values in above equation, we get -
[tex]80 * 5 = 70 * V_2\\V_2 = 5.71[/tex]
Volume will the gas occupy at [tex]70[/tex] kPa [tex]= 5.71[/tex]

The two agents that are the biggest proponents of chemical weathering are water and carbon dioxide. Water is used in a process called Hydrolysis which uses it to break down substances such feldspar in granite rocks changing to clay. While Carbon Dioxide in the atmosphere dissolves in rainwater forming carbonic acid, which slowly dissolve rocks when it comes into contact with them.
As a sodium atom is oxidized the number of protons in its nucleus
Answer:
The proton remains the same.
Explanation:
Oxidation is simply defined as the loss of electron(s) during a chemical reaction either by an atom, molecule or ion.
Oxidation is strictly on the transfer of electron(s) and not proton.
A metal that undergoes oxidation still has its protons intact otherwise it will not be called the ion of the metal since atomic number is called the proton number.
Sodium (Na) undergoes oxidation as follow:
Na —> Na+ + e-
Na is called sodium metal.
Na+ is called sodium ion.
Na has 11 electrons and 11 protons
Na+ has 10 electrons and 11 protons
From the above illustration, we can see that the protons of Na and Na+ are the same why their electrons differ because Na+ indicates that 1 electron has been loss or transferred.

Order the following in terms of decreasing atomic radius:
Ba, Cs, Hf, Bi, Ta
Answer:
Cs > Ba > Bi > Hf > Ta
Explanation:
The atomic radius of a chemical element defined as the distance between nucleus and electron from the center.
The atomic number and atomic radius of given elements are:
Barium (Ba):
Atomic number - (56)
Atomic radius - 268 pm
Caesium (Cs)
Atomic number - 55
Atomic radius - 343 pm
Hafnium (Hf):
Atomic number - 72
Atomic radius - 225 pm
Bismuth (Bi):
Atomic number - 83
Atomic radius - 230
Tantalum (Ta):
Atomic number - 73
Atomic radius - 220 pm
According to the given atomic radius the decreasing order of atomic radius is Cs > Ba > Bi > Hf > Ta.
Caesium has highest atomic radius among all even though lowest atomic number because the force of attraction between the nucleus and the outermost electron is low and outermost electron are loosely held.
Barium (Ba) has lower atomic number than Bismuth (Bi) but still atomic radius of Barium is high because moving across the periodic table atomic radius decreases as force of attraction between nucleus and outer electrons is high.
Bismuth (Bi) has higher atomic number that Hafnium (Hf), atomic radius of Bi is more than Hf.
Tantalum (Ta) have higher atomic number than Hafnium (Hf) but still have lower atomic radius as as force of attraction between nucleus and outer electrons is high.
Hence, the decreasing atomic radius is Cs > Ba > Bi > Hf > Ta.
