Zinc is amphoteric which means it reacts with both acids and alkalis.
The balanced equation is: Zn + 2NaOH + 2H2O --> Na2Zn(OH)4 + H2(g).
Sodium zincate and hydrogen gas are the products.
Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds.
Explanation:
When an acid is dissolved in water it forms hydrogen ions (H+) that combine with water to form the hydronium ion (H3O+) .
A tetrahedral carbon is sp3 hybridized while a linear carbon is sp hybridized.
Carbon is a chemical element with the symbol C and atomic number 6. It is a non-metal and is tetravalent. That atom donates four electrons to form a covalent chemical bond. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025% of the Earth's crust.
Carbon is used in some form in almost every industry in the world. It is used as fuel in the form of coal, methane gas, and crude oil (used to make gasoline). It is used to manufacture all kinds of materials, including plastics and alloys such as steel (a combination of carbon and iron). Carbon is an essential element for all life forms on earth. Carbon uptake and release are part of all plant and animal life, whether these life forms take up carbon to help make food or release carbon as part of respiration. Carbon is in constant motion from place to place.
