It is the same like the aldaric acid of L-Allose because the top and bottom groups are the same we can rotate it without changing the configuration
check the attached picture:
- The structure is in Meso form so both compound and its mirror image have the same structure (optically inactive)
<u>Answer:</u> The balanced molecular equation is written below.
<u>Explanation:</u>
A molecular equation is defined as the chemical equation in which the ionic compounds are written as molecules rather than component ions.
When zinc (II) nitrate reacts with sodium hydroxide, it leads to the formation of white precipitate of zinc (II) hydroxide and an aqueous solution of sodium nitrate.
The balanced chemical equation for the above reaction follows:
By Stoichiometry of the reaction:
1 mole of aqueous solution of zinc (II) nitrate reacts with 1 mole of aqueous solution of sodium hydroxide to produce 1 mole of solid zinc hydroxide and 2 moles of aqueous solution of sodium nitrate
Hence, the balanced molecular equation is written above.
Answer:
Explanation:
The changes in properties from metals to non-metals on a periodic table can be measured and determined by the metallicity or electropositivity of elements.
Metallicity is a measure of the tendency of atoms of an element to lose electrons.
a.
Down a periodic group, metallicity increases.
b.
Across a period from left to right electropositivity or metallicity decreases.
Metals are found in the left part of periodic table and the most reactive metal sits in the lower left corner. Non-metals are towards the right side of the table.
The mantle layer is more dense closest to the core.
