Determine the pressure of a 6.4L sample of oxygen gas at 300K and 100KPa, after the gas is compressed to 2.40L at 900K.

Answers

Answer 1

The pressure : 800 kPa

Further explanation

Boyle's law and Gay Lussac's law  

[tex]\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}[/tex]

P1 = initial gas pressure (N/m² or Pa)  

V1 = initial gas volume (m³)  

P2 = gas end pressure  

V2 = the final volume of gas  

T1 = initial gas temperature (K)  

T2 = gas end temperature  

The pressure after the gas is compressed :

[tex]\tt \dfrac{100\times 6.4}{300}=\dfrac{P_2\times 2.4}{900}\\\\P_2=800~KPa[/tex]

No

Explanation:

The physical and chemical properties of substances are usually difference from those of the elements that makes them up.

Compounds are substances composed of two or more kinds of atoms joined together in a definite grouping.

The properties of a compound are distinct and different from those of the individual elements that are combined in its make-up.

There is free rotation about the carbons of ethane but not th
of ethane. This is due to the fact that
A. the carbons in ethane are round
Balkenes do not rotate
C. the carbons in ethane are linked by double bonds
D. the carbon in ethane are smaller than those of ethane​

Answers

Answer:

C. the carbons in ethene are linked by double bonds

Explanation:

The reason for the lack of free rotation about the carbons of ethene is that they are linked with with double bonds.

In single bonds afforded with the ethane compound, there is free rotation.

The double bonds confer a special restriction on the rotational potential of the bonded atoms round the carbon.

The sedimentary rocks that are formed from physical/chemical process within the earth are given the general name of chemical precipitation.

What do you mean by the chemical precipitation ?

Chemical precipitation is the process of turning a liquid into a solid by either making the liquid insoluble or making it very saturated.

Chemical precipitation, which starts when water moving through rock dissolves part of the minerals, creates chemical sedimentary rocks. When the water evaporates, the minerals are finally redeposited or precipitated after being moved away from their source.

A chemical compound that develops when the solution it was dissolved in, often water, evaporates and leaves the compound behind is known as a chemical precipitate.

Thus,Chemical precipitation is the process that gives rise to chemical sedimentary rocks including limestone, halite, and flint.

Conglomerate is closely related to sandstone and displays many of the same types of sedimentary structures. Sandstone is a notably popular building material, used for things like flagstones and tile.

Conglomerate rocks are colorful and attractive; however, it is rarely used as ornamental stone for interior use because of its unreliable physical strength and durability.

Conglomerate has very few commercial uses, though it can be crushed to make a fine aggregate that can be used when a low-performance material is needed.

Conglomerate forms where sediments of rounded clasts at least two millimeters in diameter accumulate. Because of the large size of the clasts, it takes a very strong water current to transport and shape the rocks. As they tumble through the running water or moving waves, they form their rounded shape.

These rocks can be found in sedimentary rock sequences of all ages. They probably make up less than one percent by weight of all sedimentary rocks.

What is a chemical reaction?

A chemical reaction can be described as a reaction that brings the chemical conversion of one chemical substance to another chemical substance. The reactions cause chemical changes that include the rearrangement of electrons in order to create and break bonds between atoms.

The compound or molecules which are primarily utilized in a reaction are called reactants. Chemical reactions give products, which possess characteristics different from the reactants of the reaction.

Chemical reactions take place at a definite rate of reaction at a given concentration, temperature, and pressure. The rate of reaction increases with the rising temperature of the reaction as more activation energy is available for reactant molcules collisions.

Therefore, in a chemical reaction reactants and products can be present as Molecules, ions, and pure elements.

A motorcycle starts at rest and moves a distance of 460m .
If it has constant acceleration of 4m55 m/s2 what is its final velocity

Answers

Answer:

The final velocity of the motorcycle is 64.7 m/s

Note: Since the value for the acceleration of the motorcycle is not clear, it is assumed to be 4.55 m/s² in the calculation

Explanation:

Using the equation of motion that contains all the given values in the question: v² = u² + 2as

where v is final velocity; u is initial velocity; a is acceleration; s is horizontal distance

v = ?, u = 0 (since the motorcycle starts from rest), a = 4.55 m/s², s = 460 m

v² = 0² + 2 * 4.55 * 460

v² = 4186

take square root of both sides

v = 64.7 m/s

Therefore, the final velocity of the motorcycle is 64.7 m/s

A saturated solution is a solution that contains just as much solute as it can normally hold at a given temperature in the presence of undissolved solute. An unsaturated solution contains less solute than it can normally hold at a given temperature. A saturated solution can not dissolve more solute whereas an unsaturated solution can comfortably dissolve more solute until it attains saturation at a specified temperature.

The products often have completely different properties than the reactants. The products usually have more atoms than the reactants. The products are usually more toxic than the reactants.

Answers

Answer:

The products often have completely different properties than the reactants.

Explanation:

In a chemical reaction, the products are often completely different from the reactants.

When chemical reactions takes place, the species rearranges to form new bonds and to attain stability.

Therefore, the new products formed usually have completely different properties when compared to the reactants.

Also, in chemical reactions, mass is always conserved. The mass of the products and reactants are usually the same.
