One benefit of using ph instead of molar concentrations is that since molarity is a rate of “ moles per liter" , Molarity (M) is used to measure the concentration of hydrogen ions in a solution, which is used with pH applications. ... The H+ is the molarity number, which shows the concentration of hydrogen ions in the solution.
Answer:
single bond= 1 sigma bond
so basically 1
Explanation:
Usually, all bonds between atoms in most organic compounds contain one sigma bond each. If it is a single bond, it contains only sigma bond. Multiple bonds (double and triple), however, contains sigma and pi bonds. Double bonds have one each, and triple bonds have one sigma bond and two pi bonds
What is the percent by mass of sodium in Na2SO4? total mass of element in compound molar mass of compound Use %Element x 100
I think its 2-, it gained 2 electrons.
Answer:
Chemical bond can be define as a force holding atoms firmly together to a form molecules.
Explanation:
Chemical bond is a strong attraction between atoms, molecules or ions that enhance the formation of chemical compounds. The bonds may be due from the electrostatic force of attraction between opposite charged ions or through the sharing of electrons.
Types of chemical bond
There are four types of chemical bonds
- covalent bond
- polar bond
- ionic bond
- hydrogen bond
Ionic bond involves the transfer of an electron which involves one atom receiving and the other giving out
Covalent bond involves the sharing of electrons between two atoms
Polar bonds involves two atoms connected by covalent bonds which may exert different attractions for the electrons in the bond resulting into unevenly charges distribution
Hydrogen bond: this is found mostly in water H2O. They are polarized
