Answer:
4 L
Explanation:
Ideal gas law is P1V1T2=P2V2T1
V2=P1V1/P2
T is not necessary to add since it is constant.
Answer:
C. fluorine (F) and chlorine (Cl)
D. arsenic (As) and antimony (Sb)
Explanation:
In the periodic table , all the elements are arranged according to the atomic number ,
and the elements are placed in groups and periods ,
The elements with similar chemical and physical properties are placed in a common group .
The elements present in the same group have the same number of valence electrons in the valence shell .
Hence , from the given options ,
fluorine (F) and chlorine (Cl) belongs to group 17 with 7 valence electrons in the outermost shell .
arsenic (As) and antimony (Sb) belong to group 15 with 3 valence electrons in the outermost shell .
Answer:
2-Butene
Explanation:
The first step is the <u>ionization</u> of the acid to produce the hydronium ion. Then the OH will attack this ion to produce a <u>charged species</u> that can be stabilized when <u>H2O is produced</u>.
Then an <u>elimination</u> takes place to produce the more <u>substituted alkene</u> 2-butene and the <u>hydronium ion</u> is gain produced.
Answer:
Explanation:
Electrovalent is a word often associated with chemical bonding in the field of chemistry. It is special type of bond that occurs between metals and non-metals.
These bond types are interatomic interactions occurring between two atoms to ensure that they attain stable configurations.
- This bond type is also known as ionic bonds.
- It occurs between two species with a large electronegative diffference i.e one specie is electropositive and the other highly electronegative.
- The more electropositive specie is metal and it readily loses its valence electrons.
- The electronegative non-metal gains the electrons and becomes negatively charged.
- The electrostatic attraction between the metal and non-metals yields the electrovalent bonds.
Magnesium and oxygen reacting to form magnesium oxide is a synthesis reaction. This reaction occurs when many reactants proceeds to reaction forming a single product. Synthesis reactions release energy in the form of light or heat, therefore they are exothermic reaction.
