Explanation:
A geological process where materials of Earth are transported from one place to another by natural forces like wind or water is called erosion.
When materials of Earth are deposited over a certain landmark due to transportation by natural forces then this process is called deposition.
The four major causes of erosion and deposition are as follows.
Gravity - Force that is responsible for attracting an object towards the center of Earth.
Running water - Water present in the rivers, oceans or lakes is moving from one place to another. Also, along with it carries pebbles or other materials.
Wind Waves - This is basically air and it keeps on moving from one place to another all the time. Wind waves tend to carry dust particles or other materials along with it.
Glaciers - When a mass of ice that is formed by accumulation and compaction of snow over mountains or around the poles tends to move slowly is called glaciers.

Aleena visited a Natural Gas Compressing unit and found that the gas can be liquefied under specific conditions of temperature and pressure. While sharing her experience with friends she got confused. Help her to identify the correct set of conditions.
(a) Low temperature, low pressure
(b) High temperature, lowpressure
(c) Low temperature, highpressure
Answers
Answer:
(c) Low temperature, high pressure
Explanation:
Liquefaction of a gas means the conversion of the gas to liquid. To convert a gas to liquid, we have to look a bit at the statements of the kinetic theory of gases.
Gases show ideal behavior within the range of high temperature and low pressure. Under these conditions, minimum intermolecular interactions occur between gas molecules.
However, as the temperature is deceased and pressure in increased, intermolecular interactions become significant and the gas begins to liquefy.

Find the mass of carbon present in 0.92 g of Ethanol, [tex]C_2 H_5 OH[/tex]
Answers
0.92 × 1/46 × 2/1 × 12/1 =
0.02 × 2 × 12 =
0.04 × 12 =
0.48 gr carbon
The mass of carbon in one mole of ethanol (46.03 g) is 12.0 g. Thus, mass of carbon in 0.92 g of ethanol is 0.48 g.
What is ethanol?Ethanol is an alcohol with the formula C2H5OH. This organic compound having a molecular weight of 46.03 g/mol.
Atomic mass of carbon = 12.01 g/mol
oxygen = 16 g/mol
hydrogen = 1.01 g/mol
Thus total mass of one mole of ethanol = (12.01×2) +(16) +(6×1.01) = 46.03 g/mol
46.03 g of ethanol contains 2402 g of carbon. Thus mass of carbon in 0.92 g of ethanol is calculated as follows;
(24.02 × 0.92) / 46.03 = 0.48 g
Hence, the mass of carbon in 0.92 g of ethanol is 0.48 g.

2Al + 6HCl --> 2AlCl3 + 3H2 Aluminium reacts with hydrochloric acid. How many grams of aluminum are necessary to produce 11 L of hydrogen gas at STP? ( 8.8 g )
Answers
Answer:
8.8g of Al are necessaries
Explanation:
Based on the reaction, 2 moles of Al are required to produce 3 moles of hydrogen gas.
To solve this question we must find the moles of H2 in 11L at STP using PV = nRT. With these moles we can find the moles of Al required and its mass as follows:
Moles H2:
PV = nRT; PV/RT = n
Where P is pressure = 1atm at STP; V is volume = 11L; R is gas constant = 0.082atmL/molK and T is absolute temperature = 273.15K at STP
Replacing:
1atm*11L/0.082atmL/molK*273.15K = n
n = 0.491 moles of H2 must be produced
Moles Al:
0.491 moles of H2 * (2mol Al / 3mol H2) = 0.327moles of Al are required
Mass Al -Molar mass: 26.98g/mol-:
0.327moles of Al * (26.98g / mol) = 8.8g of Al are necessaries
Given: 2 AgNO3 + Cu -> Cu(NO3)2 + 2 Ag How many grams of AG can be produced if 200.0g of AgNO3 used?
Answers
Answer:
127 g of Ag are made in the reaction.
Explanation:
Reaction is: 2 AgNO₃ + Cu → Cu(NO₃)₂ + 2 Ag
If we only have data from nitrate, we assume the Cu is in excess.
We determine the moles of silver nitrate:
Mass / Molar mass → 200 g / 169.87 g/mol = 1.18 moles
Ratio is 2:2. If 2 moles of silver nitrate produce 2 moles of Ag, then
1.18 moles of salt, will produce 1.18 moles of silver
We convert mass to moles:
1.18 mol . 107.87 g/mol = 127 g

What is the value of K?
Answers
Answer:
K= 0.0275
Explanation:
The K of a reaction is defined as the ratio between the concentration of products over concentration of reactants powered to its coefficient. In the reaction of the problem, K is:
K = [NH3]² / [N2] [H2]³
Replacing the concentrations in K:
K = [8.62M]² / [9.76M] [6.52M]³
K= 0.0275Answer:
The value of K is 0.027.
Explanation:
Chemical equilibrium is a state of a reversible chemical system in which no changes are observed as time passes, despite the fact that the substances present continue to react with each other. That is, the chemical equilibrium is established when there are two opposite reactions that take place simultaneously at the same speed.
The Law of Mass Action says that the product of the equilibrium concentrations of the products raised to their respective stoichiometric coefficients, divided by the product of the concentrations of the reactants in the equilibrium raised to their respective stoichiometric coefficients, is a constant for each temperature, called the equilibrium constant Kc. So, being:
aA + bB ⇄ cC + dD
Then: [tex]Kc=\frac{[C]^{c} *[D]^{d} }{[A]^{a} *[B]^{b} }[/tex]
In this case, the reaction is:
N₂ + 3 H₂ ⇒ 2 NH₃
So, the equilibrium constant is:
[tex]Kc=\frac{[NH_{3} ]^{2} }{[N_{2} ]*[H_{2} ]^{3} }[/tex]
Being:
[N₂] = 9.76 [H₂] = 6.52 [NH₃]= 8.62Replacing:
[tex]Kc=\frac{8.62^{2} }{9.76*6.52^{3} }[/tex]
Solving
Kc= 0.027
The value of K is 0.027.

what is electroplating? write complete process of electro plating with the example
Answers
Answer:
Electroplating is the process of applying a metal coating on another piece of metal (or another conductive surface) through an electro-deposition process. In electroplating, the deposited metal becomes part of the existing product with the plating/coating.
Explanation:
To understand the concept further, let’s take an example of a gold coating. In this instance, a layer of gold is to be electrodeposited on metallic jewellery to enhance its appearance.Usually, the gold plating is connected to the anode (+ve charged electrode) of the circuit and the jewellery is kept at the cathode (-ve charged electrode). Both are kept immersed in a highly developed electrolytic bat (solution). At this stage, a DC current is supplied to the anode that oxidizes the gold atoms and dissolves them into the solution.The dissolved ions of gold are reduced at the cathode and plated on the jewellery.However, there are major factors that influence the last plating. These include:The voltage level of current.The temperature and chemical composition of the bath.The current length of time.The distance between the cathode and the anode.( ◜‿◝ )♡
