What development led to the realization that Dalton's atomic model was too simple?.

1 answer:

8 0

The Dalton's atomic model has been considered too simple, with the development of the subatomic particles.

The atom has been the smallest part of the matter. It has been developed with the atomic model theory introduced by Dalton.

<h3>Dalton's model</h3>

According to Dalton's atomic theory, the atom has been the smallest individual unit of matter. It has not been divided further, and has been, consisting different for every material.

<h3 /><h3>Failure of Dalton's atomic model </h3>

The Dalton model has been, consisting of atom as the smallest individual particle. It has been considered to be not divided further.

However, the study revealed the existence of subatomic particles. It has been led to the development of electrons, protons, and neutrons as the smaller particles than atom.

However, the atom has been the unit that involves in the reaction.

Thus, the development of subatomic particles led to the consideration of Dalton's atomic model as too simple.

4.60 g of of H₂O form when all the butane burns.

<h3>What is butane ?</h3>

One of the smallest liquid streams frequently created in a refinery is butane. Ten hydrogen atoms and four carbon atoms make up the butane molecule. Typically, butane is either marketed as a finished product or is blended into LPG or gasoline in tiny quantities.

It is frequently employed as a fuel for portable stoves and cigarette lighters, as a propellant in aerosols, as a heating fuel, as a refrigerant, and in the production of a broad variety of goods. Liquefied petroleum gas and butane both exist (LPG).

Butane has a low level of toxicity. In butane misuse, high exposure concentrations can be anticipated. Central nervous system (CNS) and cardiac consequences are the most frequently seen effects in cases of misuse.

How can you determine the specific heat of a metal using a calorimeter

zhannawk [14.2K]

Answer:

One can determine the specific heat of the metal through using the clarimeter, water, thermometer and using heat equations.

Explanation:

You can learn about heat effects and calorimetery through a simple experiment by boiling water and heating up the metal in it. Then, pour it into your calorimeter and the heat will flow from the metal to the water. The two equlibria will meet: the metal will loose heat into its surroundings (the water) and teh water will absorb the heat. The heat flow for the water is the same as it is for the metal, the only difference being is the negative sign indicating the loss of the heat of the metal.

In terms of theromdynamics, we can deteremine the heat flow for the metal becasue it would be equal to the mangnitued but opposite in direction. Thus, we can say that the specific heat of water qH2O = -qmetal.

2. Use the Henderson-Hasselbalch equation to estimate the pH of a buffer solution that is composed of 20 mL of 10 M sodium forma

Mkey [24]

Answer:

pH of buffer =4.75

Explanation:

The pH of buffer solution is calculated using Henderson Hassalbalch's equation:

$pH=pKa+log[\frac{[salt]}{[acid]}$

Given:

pKa = 3.75

concentration of acid = concentration of formic acid = 1 M

concentration of salt = concentration of sodium formate = 10 M

$pH=3.75+log[\frac{10}{1}]=3.75+1=4.75$

pH of buffer =4.75

Pick a "for every" statement about copper and silver nitrate for this reaction.

maxonik [38]

From the equation of the reaction; for every 1 mole of copper, the reaction uses 2 moles of silver nitrate.

<h3>What is a reaction?</h3>

A chemical reaction involves the transformation of one chemical specie into another. The reaction is not shown here hence the question is incomplete.

However, the reaction should be of the sort; Cu + 2AgNO3 ---> Cu(NO3)2 + Cu. Thus, for every 1 mole of copper, the reaction uses 2 moles of silver nitrate.
