The atoms of element differ from each other based on the number of protons or electrons they have. The number of protons or electrons is called the atomic number of an element which serves as its original identity.

<span>Now, an isotope of an element differs in their number of neutrons but the number of protons or electrons are similar.</span>

Which sequence represents the relationship between pressure and volume of an ideal gas as explained by the kinetic-molecular the
Svetlanka [38]
<h2>Answer : Option C) Smaller volume - crowded particles - more collisions - high pressure</h2><h3>Explanation : </h3>

The kinetic molecular theory of gases explains that if there is small volume of gas there will be more crowding of the gas molecules inside the container. The crowded gas molecules will collide with each other and also with the walls of container as a result, exchange of energies will take place. Which will increase the pressure inside the container, and will raise the pressure than the initial pressure.

Why does salt dissolve in water?
tigry1 [53]
The water dissolves the salt because the water molecules are able to interact with the salt-forming particles, called ions. When the water Interacts with the trainers of the salt ions, the solid salt crystal structure Suffers breakdown, until the trainers of the salt ions are completely surrounded by water molecules. At this time the salt is fully dissolved by water.

Which organism has a central brain A.sponge B. hydra C. flatworm D. fish
Scilla [17]
D. Fish
The brain is part of an organism's central nervous system. Simpler organisms such as sponges, hydrae, and flatworms lack the complexity in their central nervous systems to have a brain. A fish, on the other hand, is complex enough to have a central brain.

Nitroglycerine decomposes violently according to the chemical equation below. What mass of carbon dioxide gas is produced from t
AveGali [126]

Answer : The mass of CO_2  produced is, 7.74 grams

Solution : Given,

Mass of C_3H_5(NO_3)_3 = 13.3 g

Molar mass of C_3H_5(NO_3)_3 = 227 g/mole

Molar mass of CO_2 = 44 g/mole

First we have to calculate the moles of C_3H_5(NO_3)_3.

\text{ Moles of }C_3H_5(NO_3)_3=\frac{\text{ Mass of }C_3H_5(NO_3)_3}{\text{ Molar mass of }C_3H_5(NO_3)_3}=\frac{13.3g}{227g/mole}=0.0586moles

Now we have to calculate the moles of CO_2

The balanced chemical reaction is,

4C_3H_5(NO_3)_3\rightarrow 12CO_2(g)+6N_2(g)+10H_2O(g)+O_2(g)

From the reaction, we conclude that

As, 4 mole of C_3H_5(NO_3)_3 react to give 12 mole of CO_2

So, 0.0586 moles of C_3H_5(NO_3)_3 react to give 0.0586\times \frac{12}{4}=0.176 moles of CO_2

Now we have to calculate the mass of CO_2

\text{ Mass of }CO_2=\text{ Moles of }CO_2\times \text{ Molar mass of }CO_2

\text{ Mass of }CO_2=(0.176moles)\times (44g/mole)=7.74g

Thus, the mass of CO_2  produced is, 7.74 grams
