Answer:

The water falls to the earth as precipitation, such as rain, hail, sleet, and snow. When precipitation reaches the earth's surface, some of it will flow along the surface of the land and enter surface water like lakes, streams, and rivers, as runoff. The rest of it soaks or percolates into the soil, called

Hi, the answer is 3510g

Step-by-step explanation:-

We know that density of a substance tells us the mass of exactly one unit of volume of given substance. In this question,

Aluminium density = 2.70g/mL

So,

V = L x W x H = 1300 cm³ = 1300 mL

m = D x V = (2.70 / 1300) = 3510g

Answer:Water pollution can come from a variety of sources. Pollution can enter water directly, through both legal and illegal discharges from factories, for example, or imperfect water treatment plants. Spills and leaks from oil pipelines or hydraulic fracturing (fracking) operations can degrade water supplies.

Explanation:

since the unit for the heat of fusion is kJ/mol, you're going to have to convert the grams into moles in order to cancel out the unit. After that, you can solve like normal.

Specific heat capacity of a substance is the amount of heat required to raise the temperature by one degree Celsius of one gram of a substance. Therefore, the amount of heat required to melt 2108 g of water is 703.7kJ.

Enthalpy term is basically used in thermodynamics to show the overall energy that a matter have. Mathematically, Enthalpy is directly proportional to specific heat capacity of a substances.

Mathematically,

q = n ×ΔH

where

q = amount of heat=?

ΔH = enthalpy=6.010 kJ/mol

n = no of moles

n = w / M.M

w = given mass

M.M = molar mass

moles of water=2108 g ÷18g/mol

                             =117.1 mol

substituting all the given values in the above equation, we get

q =6.010 kJ/mol ×117.1 mol

    =703.7kJ

Therefore, the amount of heat required to melt 2108 g of water is 703.7kJ.

Answer:

The correct answer is Science is objective, whereas pseudoscience is subjective. Pseudoscience includes beliefs, theories, or practices that have been or are considered scientific, but have no basis in scientific fact. This could mean they were disproved scientifically, can't be tested or lack evidence to support them.

Answer:

Sand

Explanation:

If you get salt or sugar in your water, you have to legit desalinate it to get the water and item out. You need to evaporate the water by increasing temperature and then lower temperature to separate the substances.

If you have alcohol, you need to distill it by trapping it and stuff.

With sand, the molecules are much larger which lets you separate the substances easily.

For example, on a beach, you can slap a handful of sand in your pail, but the sand sinks to the bottom right? You can just pour out the water.

Answer:D

Explanation:

Answer:

The behavior of molecules in different phases of matter represents a balance between the kinetic energies of the molecules and the attractive forces between them. All molecules are attracted to each other. The molecules are in the solid-state. At higher temperatures, the kinetic energy of the molecules is higher.

Molecules are the various elements linked together and are present in the matter. The molecules in different phases of matter are represented by kinetic energies and attractive forces.

The kinetic molecular theory of matter elucidates the composition of the matter of particles of tiny size. The theory explains matter like gas, liquids, and solids.

The different states of matter explain the constant movement and negligible intermolecular force and volume of the particles. The particle matter is said to undergo elastic collision.

The molecules of solids have low kinetic energy whereas the molecules of liquids and gases show high kinetic energy as the particles are placed at larger distances.

Therefore, the state of matter affects the behavior of molecules.

Solubility has been the property of the substance to get dissolved to form the solution. Methanol (CH₃OH) is more soluble in water than Diiodomethane (CH₂I₂).

Solubility is best defined as the capability of the substance to get dissolved or dissociated into a solvent for the formation of the solution at a given temperature. The solubility of the various substances varies and is an important part of the mixture and solution.

Solubility in water has been the measure of the solute to get dissolved in water. The pressure and the temperature of the system directly affect the solubility of any substance in a solvent. Water is a polar molecule with hydrogen bonds in a great solvent that dissolves almost all the molecules like salt, sugar, etc.

Methanol is soluble in water as it contains hydrogen bonds as the intermolecular forces that interact with the polar water molecule by the virtue of the hydroxide and the hydrogen ions that show the molecular attraction and allows the molecule to get dissolved.

Therefore, methanol is soluble in water.
