According to Dalton's atomic theory, atoms of different elements combine in simple whole-number ratios to form compounds.

As the name implies, Dalton's atomic theory is a theory proposed by an English scientist named John Dalton in the 1900's.

The Dalton's atomic theory is composed of five main parts, which are as follows:

Therefore, in accordance to Dalton's atomic theory, atoms of different elements combine in simple whole-number ratios to form compounds.

Answer:

A- Dry with low humidity

Explanation:

The hydrosphere includes the water which is on the surface of the earth, below the ground and in the air.  

On analyzing the climatic conditions in the tropics due to the interaction of the atmosphere and hydrosphere, the presence of water droplets in tropics is less resulting in less humidity and, thus the climatic condition is dry.

Therefore the climatic condition that is typically found in tropics due to interaction of the atmosphere and hydrosphere is dry with low humidity.

Answer: Its C, c is a solid state

the answer :

Hi there !

The answer is "C"

; due to the intermolecular forces of attraction

Answer:

False

Explanation:

As I like to think of it, equilibrium will shift either 'forwards' (to increase products) or 'backwards' (to increase reactants) to oppose any change in system;

If heat is added, the equilibrium will shift in the direction that reduces heat within the system;

In other words, it will shift in favour of the endothermic reaction, i.e. the reaction where heat is gained by the molecules/atoms and therefore taken out from the system;

If the 'forwards' reaction, producing NH₃, is exothermic (i.e. energy is released in the reaction), then the 'backwards' reaction is endothermic;

So the equilibrium will shift in this direction, which is the reaction of 2 NH₃ molecules producing N₂ and 3 H₂

Explanation:

Covalent compounds are generally not very hard because they are formed by two or more nonmetallic atoms.

Covalent compounds are compounds whose constituent elements are joined together by covalent bonds.

Covalent bonding occurs when two or more nonmetallic atoms of an element share valence electrons. This means that covalent compounds will not be physically hard since they constitute non-metals.

Examples of covalent compounds are:

Electrolysis is a technique that separates natural elements. It is commercially used to obtain important materials (e.g., pure metals) for construction.

Electrolysis refers to the use of an electric current to trigger non-spontaneous chemical reactions.

This technology (electrolysis) is commercially important in industry, construction and therefore also in architecture in order to extract metals and minerals from the ground.

Electrolysis uses particular electrolytic cells in order to extract highly pure metals from ores.

Answer:

These weather conditions are consistent with droughts, often characterized by hot, dry, weather. When this is the case, it is important to conserve water and use it only for necessities. Garden sprinklers are not essential, so their use can be sacrificed in order to provide more crucial services, such as drinking water. This rule has been put in place in order to avoid water shortages and energy crises, events that would be even more damaging during an emergency.

Explanation:

That is what is says in morse code.

Answer:

MORSE CODE ISN'T THAT FUN AND I'M USING A TRANSLATOR TOO SO

Explanation:

The number of moles of the solute in the solution is the product of its volume and molarity. The number of moles of copper sulphate in 0.500 L of 2.30 M solution is 1.15 moles.

Molarity of a solution is the common term used to represent the concentration of a solution. It is the ratio of its number of moles of solute to the volume of solution in liters.

Molarity = no.of moles/volume in L.

Molarity is a temperature dependant quantity.

The given solution has a volume of 0.500 L.

molarity of copper sulphate solution = 2.30 M

Thus, number of moles of copper sulphate solute dissolved in 0.50 L of water is calculated by multiplying the volume with molarity.

No. of. moles of copper sulphate = molarity × volume

= 0.500 L × 2.30 M = 1.15 moles.

Therefore, there will be 1.15 moles of copper sulphate in the solution.

According to the forces of attraction freezing point and boiling point of water are different and are not related to  strength of electrostatic forces.

Forces of attraction is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

Answer: D. transverse

Explanation:

Light is a transverse wave, while sound is a longitudinal wave.

Considering the Dalton's partial pressure, the correct answer is option a.: the total pressure of the mixture is 1.86 atm.

The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

[tex]P_{T} =P_{1} +P_{2} +...+P_{n}[/tex]

where n is the amount of gases present in the sample.

This relationship is due to the assumption that there are no attractive forces between the gases.

In this case, a mixture contains 220 mmHg of CO, 350 mmHg of Ne and 840 mmHg of He. The total pressure of the mixture can be calculated as:

[tex]P_{T} =P_{CO} +P_{Ne} +P_{He}[/tex]

[tex]P_{T} =220 mmHg +350 mmHg+840 mmHg[/tex]

Solving:

[tex]P_{T}[/tex]= 1410 mmHg

Being 760 mmHg=1 atm, then:

[tex]P_{T}=1410 mmHgx\frac{1 atm}{760 mmHg}[/tex]

Solving:

[tex]P_{T}[/tex]= 1.86 atm

Finally, the correct answer is option a.: the total pressure of the mixture is 1.86 atm.

Answer:

Anser is C Agl

Explanation:

Agl does not dissolve in water.

All of the following compounds are soluble in water except AgI because of  very high value of lattice energy. Therefore, the correct option is option C.

The capacity of a material, the solute, to combine with a different material, the solvent, is known as solubility in chemistry. Insolubility, or the solute's inability to create such a solution, is the opposite attribute. The concentration for the solute within a saturated solution—a solution where no more of the substance can be dissolved—is typically used to gauge the degree of a substance's solubility in a particular solvent. The two compounds are considered to be at the point of solubility equilibrium at this time. All of the following compounds are soluble in water except AgI because of  very high value of lattice energy.
