Help! help! plz give 4 different between orbit and orbital​
Gemiola [76]

Answer:

Differences between Orbit and Orbitals

Orbit

An orbit is the simple planar representation of an electron.

It can be simply defined as the path that gets established in a circular motion by revolving the electron around the nucleus

The shape of molecules cannot be explained by an orbit as they are non-directional by nature.

An orbit that is well-defined goes against the Heisenberg principle.

Orbital

An orbital refers to the dimensional motion of an electron around the nucleus in a three-dimensional motion.

An orbital can simply be defined as the space or the region where the electron is likely to be found the most.

The shapes of the molecules can be found out as they are directional by nature.

An ideal orbital agrees with the theory of Heisenberg’s Principles.

Someone explain it plz​
timofeeve [1]

Answer:

1). 1 mole of Carbon burnt in air

C + O2 →CO2

1 mole of carbon produces 1 mole of CO2 which is 44g of CO2

2). 1 mole of carbon is burnt in 16g of dioxygen

32g of O2 = 44g of CO2

1g of O2 = 44/32

CO2 (Dioxygen is limiting reagent)

16g of O2 = 4/32 × 16 = 22g of CO2 in one mole

3) 2 moles of Carbon burnt in 16g of dioxygen

16g of dioxygen is available, and thus it can combine with 0.5 mol of carbon to give 22g of CO2

True or False: The Periodic Table of Elements is in alphabetical order to make locating elements easier.
viva [34]

Answer:

False

Explanation:

The periodic table is in order of their atomic number. If that were true, helium would not come before boron, for example.

Express the diameter of a ground-state hydrogen atom in meters using a power of 10.
REY [17]
<span>Throughout the development of particle physics, scientists have created different models to understand the atom. When we are talking about the diameter of an atom, we would refer to the Bohr radius, which is the radius from the nucleus to the orbiting electron. In this case, a hydrogen atom has one electron, and the Bohr radius in the ground state is 5.29 x 10^{-11} meters. To find the diameter, we just multiply the Bohr radius by 2. diameter = 2 x 5.29 x 10^{-11} meters diameter = 10.58 x 10^{-11} meters diameter = 1.058 x 10^{-10} meters The diameter of a hydrogen atom in ground state is: 1.058 x 10^{-10} meters</span>

11Alexandr11 [23.1K]

Answer:

The correct answer is -

Prokaryotic unicellular -

Eubacteria - is the domain of unicellular organisms that has a prokaryotic cell

Archaebacteria - is one of the two domains of the prokaryotic organisms that are unicellular.

Eukaryotic multicellular (autotroph) -

Plantae - is the multicellular kingdom of the eukaryotic cells and as they produce their own food by photosynthesis called autotrophs.

protists - the autotrophic protists that are multicellular comes under algae, especially red algae.

Eukaryotic multicellular (heterotroph) -

Animalia - The Animalia kingdom is the kingdom of the heterotrophic eukaryotic organism that mostly has multicellular bodies. They depend on plants or other animals for their food.

Fungi - are mostly heterotrophic eukaryotic as they get their nutrient from other organisms are mostly multicellular.

Protist - some protists are heterotrophic as well.

Eukaryotic multicellular/unicellular (heterotroph/autotroph) -

Plantae

protists

Animalia

Fungi
