Oxygen and sulfur have similar chemical properties because both elements have six electrons in their outermost electron shells. Indeed, both oxygen and sulfur form molecules with two hydrogen atoms: water and hydrogen sulfide. Surprisingly, water is a liquid, yet hydrogen sulfide is a gas, even though sulfur is much larger and heavier than oxygen. Propose an explanation for this striking difference.

To show the electron configuration for an atom, what is the advantage of using an orbital notation compared to a dot structure? Orbital notation takes up less space. Orbital notation shows the spin of the electrons. Orbital notation makes it easier to count the electrons. Orbital notation shows the electron distribution in shells.

What is the ph of 1.2 time 10 to the negitive 2

Answers

Answer:

Explanation:

H⁺ = 1.2 x 10⁻²

pH = - log[H⁺]

= - log [ 1.2 x 10⁻²]

= - log1.2 + 2

= - .079 + 2

= 1.921 .

Carbon-14 is an isotope of carbon. How does it differ from other forms of carbon?

Answers

Carbon-14, also known as radiocarbon, is a radioactive isotope of carbon as compared to other forms of carbon. it contains 6 protons and 8 neutrons. The presence of such in organic materials is the basis of the radiocarbon dating method to date geological samples.

Which scientist provided a foundation for John Daltons work on the atomic structure

Answers

The correct option for above statement is:

B.Joseph Proust

Explanation:

Joseph Proust printed his Law of Definite Proportions (or Law of Constant Composition) in 1794. This law states that a compound consists of exact proportions of parts by mass no matter however the compound was created.

The scientist who provided a foundation for Dalton's work on the atomic structure is Ernest Rutherford

What is the mass of an aluminum cylinder that has a volume of 1.50m3

Answers

Answer: The mass of aluminium cylinder is 4065 kg.

Explanation:

Density is defined as the ratio of mass of the object and volume of the object.

Mathematically,

$\text{Density}=\frac{\text{Mass of the object}}{\text{Volume of the object}}$

We are given:

Density of aluminium = $2710kg/m^3$

Volume of aluminium cylinder = $1.50m^3$

Putting values in above equation, we get:

$2710kg/m^3=\frac{\text{Mass of aluminium cylinder}}{1.50m^3}\n\n\text{Mass of aluminium cylinder}=4065kg$

Hence, the mass of aluminium cylinder is 4065 kg.

Aluminium density: 2700g/m^3

therefore; 2700g/m^3 X 1.50m^3 = 4050g = 4.05Kg

Just use the units of density (mass/volume) and the units of what's given to figure it out :)
