Answer:
fruit cake is the right ans
Answer:
cold
Warm air lifted over a moving cold air mass will produce a _____ front.
Answer:
The relative conjugate acids and bases are listed below:
CH3NH2 → CH3NH3+
H2SO3→ HSO3-
NH3→ NH4+
Explanation:
In a Brønsted-Lowry acid-base reaction, a conjugate acid is the species resulting from a base accepting a proton; likewise, a conjugate base is the species formed after an acid has donated a hydrogen atom (proton).
To this end:
- HSO3- is the conjugate acid of H2SO3 i.e sulfuric acid has lost a proton (H+)
- NH4+ is the conjugate acid of NH3 i.e the base ammonia has gained a proton (H+)
- OH- is the conjugate base of H20
- CH3NH3+ is the conjugate base of the base CH3NH2 methylamine
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
