Answer:
Magnesium bromide, MgBr2, and water, H2O.
Explanation:
Hello!
In this case, since HBr is an acid and Mg(OH)2 is a base, an acid-base reaction is undergone, by which a salt and water are produced as neutralization products:
However, it need to be balanced since two bromine atoms are produced, therefore we write:
Thus, the products are magnesium bromide, MgBr2, and water, H2O.
Best regards!
Answer: The chemical equations are given below.
Explanation:
A balanced chemical reaction follows law of conservation of mass.
This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.
Single displacement reaction is defined as the reaction in which more reactive metal displaces a less reactive metal from its chemical reaction.
General equation representing single displacement reaction follows:
C is more reactive element than element A.
The reactivity of metals is judged by the series known as reactivity series. Elements lying above in the series are more reactive than the elements lying below in the series.
- 1. When solid lead metal is put in the beaker of 0.043 M solution.
Lead lies below in the reactivity series than iron. Thus, it will not replace iron from its chemical reaction.
- 2. When solid iron metal is put in the beaker of 0.044 M solution.
Iron lies above in the reactivity series than lead. Thus, it will easily replace lead from its chemical reaction.
Hence, the chemical equations are given above.
Answer:
The metals are shiny. They are solid at room temperature (except mercury) are malleable and ductile. They are good conductors of heat and electricity but as the temperature increases, their electrical conductivity decreases. The metals are to the left and center of the periodic table. The metal elements are from group 1 (except hydrogen) to 12, in addition to others that form a broken line in the periodic table of group 13 to 16
Nonmetals do not shine like metals. They are usually brittle, some hard and others soft. They are bad conductors of heat and electricity. They are located to the right in the periodic table above the broken line.
Metalloids have an intermediate behavior between metals and nonmetals. They can be bright or opaque. They change shape easily. They are better conductors of heat and electricity than nonmetals, but not as much as metals. They are semiconductors. When the temperature is increased, its electrical conductivity increases. Within the periodic table the metalloids are in a diagonal line.
The noble gases are a group of non-metallic chemical elements that, under normal conditions of pressure and temperature, are monoatomic, odorless, colorless gases. The noble gases have very weak intermolecular forces and, therefore, have very low melting and boiling points. They are placed in group 18 of the periodic table.
Answer:
CH4<HClO2<HClO<H2O<HCl
Explanation:
In ranking the compounds on the basis of increasing positive charge of hydrogen, we must consider the relative oxidation numbers of the various elements in the compounds.
Methane contains a nonpolar covalent bond, HClO2 contains a chlorine atom in +3 oxidation state, HClO contains a chlorine atom in +1 oxidation state. The more the positive charge on the halogen atom the lesser the magnitude of positive charge on the hydrogen atom. Between water and HCl, chlorine is more electro negative hence HCl will contain a more positively charged hydrogen atom than water.
Answer:
5-chloro-1,3-cyclopentadiene
Explanation:
5-chloro-1,3-cyclopentadiene will react more slowly in an SN1 reaction. ( i.e. No reaction as the product is unstable ) attached is the representation of the rate of reaction of both Halides which shows that 5-chloro-1,3-cyclopentadiene reacts the slowest .
Also During SN1 reaction Carbocation is formed .
