Answer:
NaNO₃ and AgCl are the two products that can be formed.
Sodium nitrate, an aqueous solution and a solid silver chloride (precipitate)
Explanation:
We determine the dissociation of both salts
AgNO₃ (aq) → Ag⁺ (aq) + NO₃⁻ (aq)
NaCl (aq) → Na⁺ (aq) + Cl⁻ (aq)
We make the ionic equation:
Ag⁺ (aq) + NO₃⁻ (aq) + Na⁺ (aq) + Cl⁻ (aq) → NaNO₃(aq) + AgCl (s) ↓
Answer: The correct option is D.
Explanation: Nonmetallic minerals are the chemical elements from which no new product can be formed when they are melted. For Example: Sand, marble etc..
For the given options:
Option A: Wood is a type of cellulose and is not considered as a nonmetallic mineral resource.
Option B: Iron is an element because it is the smallest substance which cannot be broken down. It is not considered as a nonmetallic mineral resource.
Option C: Coal is a mixture of carbon compounds. This is very close to mineral but is an organic mineral because it contains carbon atom. Hence, it is not considered as a nonmetallic mineral resource.
Option D: Aggregate is formed by the collection of particles forming a whole mass. This is a non-metallic resource as it cannot form any new product.
Hence, the correct option is D.
Answer:
Sodium
Hydrogen
Carbon
Oxygen
Explanation:
Formula of baking soda is NaHCO₃. It is the salt consist of sodium (Na⁺) cation and bicarbonate (HCO₃⁻) anion. It is also called sodium hydrogen carbonate. It is crystalline white solid.
Elements in baking soda:
Sodium:
Sodium is present in third period and group one of periodic table. It is eleventh element of periodic table. It is alkali metal and lose one valance electron thus carry +1 charge.
Hydrogen:
It is first element of periodic table. Its atomic number is one and mass is 1.008 g/mol. It can lose its one electron and has +1 charge.
Carbon:
It is present in the group fourteen of periodic table. It can lose its four valance electrons and form four covalent bonds. Its atomic number is six and atomic weight is twelve.
Oxygen:
It is the eighth element of periodic table. It is present in group sixteen and second period of periodic table. It has six valance electrons. It is also called chalcogen because it is ore forming element.
Alkenes on reaction with meta-chloroperoxybenzoic acid (MCPBA ) produces epoxides. When styrene is reacted with mCPBA it gives 2-phenyloxirane as shown below,
