Dalton's Atomic Model
olga_2 [115]

Answer:

A theory of chemical combination, first stated by John Dalton in 1803. It involves the following postulates: (1) Elements consist of indivisible small particles (atoms). (2) All atoms of the same element are identical; different elements have different types of atom. (3) Atoms can neither be created nor destroyed. Based on all his observations, Dalton proposed his model of an atom. It is often referred to as the billiard ball model. He defined an atom to be a ball-like structure, as the concepts of atomic nucleus and electrons were unknown at the time.

John Dalton developed a crude method for measuring the masses of the elements in a compound. His law of multiple proportions states that when two elements form more than one compound, masses of one element that combine with a fixed mass of the other are in a ratio of small whole numbers.

Consider the following chemical reaction:
laiz [17]

Answer:

B. 1.65 L

Explanation:

Step 1: Write the balanced equation

2 SO₂(g) + O₂(g) ⇒ 2 SO₃(g)

Step 2: Calculate the moles of SO₂

The pressure of the gas is 1.20 atm and the temperature 25 °C (298 K). We can calculate the moles using the ideal gas equation.

P × V = n × R × T

n = P × V / R × T

n = 1.20 atm × 1.50 L / (0.0821 atm.L/mol.K) × 298 K = 0.0736 mol

Step 3: Calculate the moles of SO₃ produced

0.0736 mol SO₂ × 2 mol SO₃/2 mol SO₂ = 0.0736 mol SO₃

Step 4: Calculate the volume occupied by 0.0736 moles of SO₃ at STP

At STP, 1 mole of an ideal gas occupies 22.4 L.

0.0736 mol × 22.4 L/1 mol = 1.65 L

A cylinder with a mass of 98 grams is made of copper (density 8.94 g/cm³). If the radius of the cylinder is 2.0 cm, what is the
sasho [114]

The height of the described cylinder is 0.85 cm

Mass= 98g

Density= 8.9g/cm^3

Density= (mass/volume)

Substitute the values

8.94= 98/ volume

Volume= \frac{98}{8.94}

Volume= 10.97cm^{3}

Volume of a cylinder can be found with (V = π r 2 h.)

h= height of cylinder ?

radius= 2cm

Substitute the values

10.97= π × 2^{2} × h

h= 10.97/12.57

h= 0.85 cm

Therefore, height of the described cylinder is 0.85 cm
