In a microwave oven, microwaves emitted by a small antenna are directed into the cooking compartment, and as they enter, they pass a set of turning metal fan blades.
it used to convey information from one place to another through intervening media,like- Radios and televisions
used in hospitals to produce photograph of bone to check for break or fracture.They can penetrate less dense matter such body tissue and skin.
For the first
H : O : H
Theres two bonds here
Each other are sigma
So 2Sigma bonds present
For the Second
I believe you wanted to write Ethyne....
In a triple bond... Theres 1sigma and 2 Pi bonds
Every single bond is a sigma bond
So
Counting all
we have
2Pi bonds and 3Sigma bonds
Answer:
The programs take two-dimensional images and allow the user to manipulate cubes and prisms to create their design sketches.
Explanation:
Instead of working with squares and triangles, the programs allow the users to manipulate cubes and prisms to create their design sketches. Additionally, the programs can take two-dimensional pictures and convert them to possible three-dimensional images.
I got you bro :)
Sorry he took your points :(

Answer:
Ionic bonding happens when an atom of an element gives one or more of its electrons to the other element's atom..it usually takes place between metal and non metal atoms...like in NaCl, Na gives its valence electron to chlorine and completes its own octet. Chlorine accepts the electron and completes its own octet too...but now both the atoms have an opposing charge and hence they attract each other to form an IONIC bond.
Ionic bonds are the strongest of the bonds...here complete transfer of electrons takes place unlike covalent bonds.
HOPE IT HELPED..

Answer: An element is a single atom.
Explanation:
An element cannot be divided into smaller parts (that was true before the physicists built atomic weapons and the Large Hadron Collider). But the definition of an atom was establish before Einstein, Oppenheimer, and Rutherford. An element is an atom. A compound is two or more atoms bonded together. Carbon is an element, and one carbon all by itself is an atom. A carbon that has some hydrogens attached (e.g, methane, CH4) are compounds. An oxygen atom is just sa single O. We write O2 since that is the form it takes in nature. O is an atom, O2 is a molecule.
