Answer:
0.00642mole
Explanation:
Molar Mass of Cu = 63.5g/mol
Mass of Cu from the question = 0.4076g
Number of mole =?
Number of mole = Mass /Molar Mass
Number of mole of Cu = 0.4076/63.5 = 0.00642mole
Answer:
NaCl+H20
Explanation:
It is a neutralisation reaction in which NaOH is a base and HCl is an acid. On reaction it forms salt and water.

Probably large earthquakes and how the seismic waves produces in such events are transmitted through the Earth gave the majority of information about the deep interior of the planet.
The earth is often referred as a blue planet because the hydrosphere looks blue and it covers 3/4 of the earths surface. So the answer is D
3. Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2 H₂O represents a neutralization reaction.
<u>Explanation:</u>
Neutralization reaction is a reaction in which an acid reacts with a base to form a slat and water.
First reaction is the decomposition reaction in which the reactant is decomposed to form 2 or more products.
Second one is the combustion reaction in which methane is burnt in presence of oxygen.
Third one is the Neutralization reaction, in which calcium hydroxide (base) reacts with sulfuric acid (acid) to form a (salt) calcium sulfate and water.
Fourth reaction is nothing but the double displacement reaction in which the ions exchanged their positions there by forming two new products.
