The reaction is a displacement reaction. Iron is more reactive than copper. Hence, it displaces copper,forming iron II sulfate and copper metal.
This reaction is an exothermic reaction, hence it releases energy. The colour change indicates that iron has displaced copper.
Answer:
2.12×10²³ atoms.
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ atoms. This simply means that 1 mole of zirconium also 6.02×10²³ atoms.
Thus, we can obtain the number of atoms present in 0.3521 mole of zirconium as follow:
1 mole of zirconium also 6.02×10²³ atoms.
Therefore, 0.3521 mole of zirconium will contain = 0.3521 × 6.02×10²³ = 2.12×10²³ atoms.
Therefore, 0.3521 mole of zirconium contains 2.12×10²³ atoms.
This is called a life span.
Answer:
The correct answer is D
Explanation:
Ice is a solid, so if heat is added to it the ice will melt causing it to form into a liquid, once the ice turns into a liquid, it begins to turn into gas.

For this question, suppose the pressure is remained constant, we can use the Charles law to find the answer.
Charles law:
V1/T1 = V2/T2
V1 and T1 are the initial volume and temperature (in K), and V2 and T2 are the final volume and temperature.
We just need to substitute in the numbers in order to find the new volume, V2.
1/5 = V2/10
5V2 = 10
V2 = 2
Therefore, the answer would be 2m3.
