Answer:
The answer to your question is Single replacement
Explanation:
Types of reaction in Chemistry
Synthesis two or more reactants combine to produce one single product
Decomposition one reactant splits producing two or more products
Single replacement One element replaces a similar one in a compound.
Double replacement Two compounds interchange their cations and anions.
Combustion one compound reacts with oxygen to produce carbon dioxide and water.
Reaction given
Fe⁺² + CuSO₄ ⇒ Cu + FeSO₄
This is a single replacement reaction
Answer: Compounds.
Explanation:
Compounds are formed when an unstable element combines with other elements, they do this by sharing electrons within their outmost shell. Compounds forms when there is a chemical bonding between two or more elements. Examples of compounds includes carbon dioxide (C, O) water (H and O), Sodium chloride (Na, Cl), methane, etc.
(0.48 gram) x (1mole / 4.0 gram) = 0.48/4.0 = 0.12 mole
Answer:
That we know about yes, but physicians still say there are more things out there. (we do not know about these yet tho)
Explanation:
Answer: Electronegativity increases as the size of an atom decrease.
Explanation: Electronegativity is the measure of the ability of an atom in a bond to attract electrons to itself.
Electronegativity increases across a period and decreases down a group.
Towards the left of the table, valence shells are less than half full, so these atoms (metals) tend
to lose electrons and have low electronegativity. Towards the right of the table, valence shells are more than half full, so these atoms (nonmetals) tend to gain electrons and have high electronegativity.
Down a group, the number of energy levels (n) increases, and so does the distance between the nucleus and the outermost orbital. The increased distance and the increased shielding weaken the nuclear attraction, and so an atom can’t attract electrons as strongly.
