If an electron moves up from the first orbit to the higher energy levels, energy will be absorbed by the electron itself and no emission line produced.
But if it moves from the orbits 6,5,4 and 3 to orbit 2, energy will be released by the electron and different emission lines wll be produced.

A helium filled blimp will rise just so high into the atmosphere and then stop. Why? Will a smaller blimp rise higher than a lar

tankabanditka [31]

Answer:

See explanation

Explanation:

When a helium blimp rises in the atmosphere, a point eventually comes when the buoyancy of the blimp compared to the air it displaces is no longer greater than gravity's pull on the blimp hence it stops rising.

A smaller blimp will rise more than a larger blimp at the same pressure because the weight of the blimp determines the altitude to which it will rise.

Carbon monoxide is 1. an atom, an element and a mixture. 2. a molecule, element and a pure substance. 3. an atom, a compound and

SSSSS [86.1K]

Answer:

The correct answer is option (6).

Explanation:

A molecule is group of atoms of same or different kinds of element.

In carbon monoxide there is a single carbon atom and single oxygen atom. Hence, a molecule.

Compound is defined as a chemical specie which is made by the combination of different atoms.

As we can see from the chemical formula of carbon monoxide is made up of two atom of different elements that is carbon and oxygen.

A pure substance is defined as the substance which is formed by same or different type of atoms which are chemically combined in a fixed ratio by mass. They have definite set of properties.

$C+\frac{1}{2}O_2\rightarrow CO$

1 mole of carbon combined with 0.5 moles of oxygen gas to give carbon monoxide gas.
