Answer:

  • <u><em>beta decay</em></u>

Explanation:

The <em>process</em> is represented by the nuclear equation:

  • ^1_0n → ^1_1p+^0_{-1}\beta

Where:

  • n represents a neutron,
  • p represents a proton, and
  • β represents an electron.

The superscripts to the leff of each symbol is the mass number (number of protons and neutrons), and the subscript to the left means the atomic number (number of protons).

Then, in this process a neutron is being transformed into a proton by the emssion of an electron (from inside the nucleus of the atom).

This electron is named beta (β) particle, and the process is called <u><em>beta decay</em></u>, because the neutron is changing into other subatomic particles.

What is double bond,triple bond,lone pair and single bond
AlladinOne [14]

In covalent bonds, atoms share electrons. These shared electrons are known as, well, covalent bonds!

In a covalent bond, each atom contributes one electron, meaning that for every bond, there are 2 electrons residing in it.

Definitions:

A single bond is a covalent bond that contains 2 electrons.

A double bond is a covalent bond that contains 4 electrons

A triple bond is a covalent bond that contains 6 electrons

It's very common for atoms to not use all of their electrons while bonding, which means that some will be left out and aren't used in any bonds. These are called lone pairs.

Definition:

A lone pair is a pair of electrons that aren't used in bonding, and therefore remain with its original atom.

Compound 2 contains 2.0g of hydrogen and 32.0g oxygen. What is the percent compound of each element?
Dmitriy789 [7]

Note down the formula below

\boxed{\sf Mass\%\;of\; element=\dfrac{Mass\:of\:the\: element}{Mass\;of\:the\: compound}\times 100}

Mass of the compound

\\ \sf\longmapsto 32+2=34g

Mass % of Hydrogen:-

\\ \sf\longmapsto \dfrac{2}{34}\times 100

\\ \sf\longmapsto \dfrac{1}{17}\times 100

\\ \sf\longmapsto 5.8\%

Mass % of Oxygen:-

\\ \sf\longmapsto \dfrac{32}{34}\times 100

\\ \sf\longmapsto \dfrac{16}{17}\times 100

\\ \sf\longmapsto 94.2\%

How many hydrogen grams can be obtained if
kipiarov [429]

hi im breanna

Answer:

The mole is simply a very large number that is used by chemists as a unit of measurement.

Explanation:

The mole is simply a very large number,  

6.022

×

23

, that has a special property. If I have  

6.022

×

10

23

hydrogen atoms, I have a mass of 1 gram of hydrogen atoms . If I have  

6.022

×

10

23

 

H

2

molecules, I have a mass of 2 gram of hydrogen molecules. If I have  

6.022

×

10

23

 

C

atoms, I have (approximately!) 12 grams.

The mole is thus the link between the micro world of atoms and molecules, and the macro world of grams and litres, the which we can easily measure by mass or volume. The masses for a mole of each element are given on the periodic table as the atomic weight. So, if have 12 g of  

C

, I know, fairly precisely, how many atoms of carbon I have. Given this quantity, I know how many molecules of  

O

2

are required to react with the  

C

, which I could measure by mass or by volume.
