I answered the question what do you want to gave me

Answer:

CO2 is an evil necessary element. co2 is needed for our survival. we need food for survival and food is produced by the plants through photosynthesis. for photosynthesis to take place co2 is one of the vital element. so no co2,no photosyntheseis maeans no food. no food no one will survive.

We have that an element  indicated by its electron configuration, we can determine its Atomic number by selecting the electron represented on each orbit of the atom around the nucleus

Hence using the  Periodic table to read the its Atomic Number

The Periodic table is categorized using the atomic number of elements and symbols are  to aid search as well

Answer:

It is not equal to Avogadro constant

Explanation:

This is because Avogadro constant refer to the number of molecules or atoms of particles per mile substance and thus is equal to 6.022×10^23 per mile or unit of that substance.

Solution :

We know, In an electrolyte solution, the number of dissolved particles is larger because the solute breaks apart into ions. The greater the number of ions, the larger the impact on colligative properties will be.

So, the compound which will dissociate into more number of electrolyte has more vapour pressure.

Out of all given compound K₃PO₄ have highest number of particles after dissociation.

Hence, D) is the required solution.

Answer:

large supply of nutrients.

Explanation:

In a wetland, the soil is covered by water or is almost covered by water. This water may be coming upwards from an underground aquifer. Wetlands are covered by water for most of the year.

They are sheltered waters and do provide habitats for many living things.

Nutrients such as; Carbon sulfur, phosphorus, carbon, and nitrogen are cycled within the soil of wetlands hence wetlands have a large supply of nutrients.

The warm water provides moisture for hurricanes so that hurricanes are strongest over water, and become weak when they reach land.

Hurricanes are forceful winds in the air which are able to destroy even a land completely. One of the most destructive forces on earth is the hurricane. Although the process of a origin of  hurricane is complex.

They need water that is at least 80 degrees first. Air that is wet is the second component. Finally, for a hurricane to form, there must be convergent winds.

A group of thunderstorms moving across the ocean's surface signal the start of the real process. Similar to how a straw absorbs liquid, when the surface water is heated, the storm absorbs heat energy from the water. The air becomes moistened as a result.

The storm can develop into a hurricane if the wind conditions are right. The fuel is this thermal energy. Hence, option c is correct.

Answer: [tex]7.36\times 10^{23}[/tex] number of molecules of chlorine gas are needed.

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] ......(1)

Given mass of sodium chloride = 35.7 g

Molar mass of sodium chloride = 58.44 g/mol

Plugging values in equation 1:

[tex]\text{Moles of sodium chloride}=\frac{35.7g}{58.44g/mol}=0.611 mol[/tex]

The given chemical equation follows:

[tex]2Na+Cl_2\rightarrow 2NaCl[/tex]

By the stoichiometry of the reaction:

If 1 mole of sodium chloride is produced from 2 moles of chlorine gas

So, 0.611 moles of sodium chloride will be produced from = [tex]\frac{2}{1}\times 0.611=1.222mol[/tex] of chlorine gas

According to the mole concept:

1 mole of a compound contains [tex]6.022\times 10^{23}[/tex] number of molecules

So, 1.222 moles of chlorine gas will contain = [tex]\frac{6.022\times 10^{23}}{1mol}\times 1.222mol=7.36\times 10^{23}[/tex] number of molecules

Hence, [tex]7.36\times 10^{23}[/tex] number of molecules of chlorine gas is needed.

Answer:

32000atm

Explanation:

Using Boyle's law equation;

P1V1 = P2V2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (

V2 = final volume (L)

According to the question below:

P1 = 160.0 atm

P2 = 3.0 atm

V1 = 600L

V2 = ?

Using P1V1 = P2V2

160 × 600 = 3 × V2

96000 = 3V2

V2 = 96000/3

V2 = 32000atm

To Find :

Gas’s temperature in Celsius when it has a volume of 25 L, 203 mol, 143.5 atm .

Solution :

We know, by ideal gas equation :

[tex]PV =nRT\\\\T = \dfrac{PV}{nR}[/tex]

Here, R is universal gas constant and [tex]R = 0.082 \ L \ atm \ mol^{-1} \ K^{1}[/tex]

Putting all given values and R in above equation, we get :

[tex]T = \dfrac{PV}{nR}\\\\T = \dfrac{143.5\times 25}{203 \times 0.082}\ K\\\\T = 215.52\ K[/tex]

Hence, this is the required solution.

Answer:

The mouth begins the process of digestion by mechanically breaking food into smaller pieces.

Explanation:

Digestion is a crucial process that involves the break down of complex food molecules into simpler ones that are assimilable by the body. The process of digestion in humans, for example, is said to begin in the MOUTH where the food enters through.

The mouth via the use of teeth helps the initially break down the food particles using mechanical/physical method. This further helps the break down of the food into tiny particles before they are acted on enzymatically.
