The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions. According to Dalton, the atoms of same element are similar in all respects.

Answer:

If the cell was a city, what would the city have inside it for it to function as a cell?

Explanation:

The cell membrane can be a fence or wall around the city because it controls what enters and leaves the cell, and separates the cell from the outside.

The nucleus could be the city hall because it  protects DNA and controls the cell (city)

The mitochondria could be the greenhouse because it makes ATP energy from sugar + 02

The chloroplasts could be a farm or garden because it is where photosynthesis takes place and makes energy + sugar from sunlight

The ribosomes could be the factory to make stuff because it makes proteins

The endoplasmic reticulum could be a kitchen or restaurant because it helps finish proteins, and makes membranes.

The golgi apparatus could be the postal office because it finishes packages and ships proteins

The vacuoles could be a water tank because it storages water

I hope this helps. It is basically as if something was turning into a city-type thing. Like Lysosome could be a recycling center in a city.

A shortcoming of Rutherford’s model of the atom is it did not account for the fact that atoms have equal numbers of protons and electrons. Therefore, option C is correct.

Ernest Rutherford, a scientist who was born in New Zealand, developed the Rutherford model to explain an atom. Rutherford oversaw the Geiger-Marsden experiment, which, after Rutherford's analysis in 1911, indicated that J. J. Thomson's plum pudding model of the atom was flawed, in 1909.

The first person to recognize an atom's nucleus was Rutherford. He attacked gold with -particles and discovered that there was positively charged material inside the atom as a result.

It did not explain the distribution of the atom's negatively charged electrons around its positively charged nucleus.

Thus, option C is correct.

Explanation:

The Atomic mass will be the same for every isotope as the number of Neutrons changes, not the number of protons.

Neon has two major isotopes. Neon-20 and Neon-22. Out of every 250 neon atoms, 225 will be Neon-2(19.992 g/mol), and 25 will be Neon-22 (21.991 g/mol), then the average atomic mass of Neon20.1974

Atomic mass of an element can be defined as the total number of neutrons and protons present in the nucleus of an atom and the  atomic number is the number of protons present in  nucleus.

the average weight of an element is called as atomic mass while atomic number is total number of protons present in the central nucleus of the atom. Atomic mass is presented a symbolic representation of A where as atomic number is represented by the letter Z.

Atomic mass can not classified  which type of element where as Atomic number classify and identify the type of element, there are different types of isotopes of an element observed on the basis of their atomic mass where as isotopes only share the same atomic number.

Neon has two isotopes such as , N e 20, N e 21 and N e 22.The average atomic mass can be calculated as:

N e  Average atomic mass = [ 19.9924 (90.92 %)] + [ 20.9940 (0.257 %)] + [ 21.9914 (8.82 %)] a m u

In the reaction between Fe₂S₃(s) and HBr(aq), the sum of the coefficients for all reactants and products is 12.

If the reaction occurs between Fe₂S₃(s) and HBr(aq) and the equation is properly balanced with the smallest whole-number coefficients, what is the sum of the coefficients for all reactants and products?

Let's consider the unbalanced equation for the reaction between Fe₂S₃(s) and HBr(aq). This is a double displacement reaction.

Fe₂S₃(s) + HBr(aq) ⇒ FeBr₃(aq) + H₂S(g)

We will balance it using the trial and error method.

First, we will balance Fe atoms by multiplying FeBr₃ by 2.

Fe₂S₃(s) + HBr(aq) ⇒ 2 FeBr₃(aq) + H₂S(g)

Then, we will balance S atoms by multiplying H₂S by 3.

Fe₂S₃(s) + HBr(aq) ⇒ 2 FeBr₃(aq) + 3 H₂S(g)

Finally, we will get the balanced equation by multiplying HBr by 6.

Fe₂S₃(s) + 6 HBr(aq) ⇒ 2 FeBr₃(aq) + 3 H₂S(g)

The sum of the coefficients for all reactants and products is:

[tex]1 + 6 + 2 +3 = 12[/tex]

In the reaction between Fe₂S₃(s) and HBr(aq), the sum of the coefficients for all reactants and products is 12.

The diameter of a mercury atom is 151 pm and the diameter of the planet Mercury is 4,879.4 km.

Water has three states of matter namely gas, solid or ice form and liquid. Molecules in solid state are not able to move since they are tightly packed.

Molecules can move in liquid state and they moves easily in gaseous state.

Every substance have three states, that are gas, liquid and solid. In solid state, molecules are tightly packed and are unable to move apart. In liquid state, molecules have some space to move and motion of liquid is easy.

The movement of molecules in a substance depends on the space allotted for them or called the volume. More volume between molecules, easy to move apart.

Gaseous state is composed of molecules located far apart from each other and they diffuse easily. Therefore, motion in three states of water is different and moves faster in gaseous state.
