Answer:
Explanation:
The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
Oxidizing agents:
Oxidizing agents oxidize the other elements and itself gets reduced.
Reducing agents:
Reducing agents reduced the other element are it self gets oxidized.
In given example,
Magnesium is able to <u>reduced</u> the copper and copper is able to <u>oxidized</u> the magnesium.
Zinc is able to <u>oxidized</u> the magnesium and magnesium is able to <u>reduced</u> the zinc.
Copper is able to <u>oxidized</u> the zinc and zinc is able to <u>reduced</u> the copper.
Answer:
Density = 2.5 g/cm³ , The metal is aluminium.
Explanation:
Density is defined as the ratio of the mass and the volume
Thus,
Given that:
Mass = 612 grams
Volume = 245 cm³
Thus, Density is:
<u>Density = 2.5 g/cm³</u>
Metals are shiny with high density.
<u><em>The density of aluminium falls is approx 2.6 g/cm³ and not other metal's density falls in this range. </em></u>
<u><em>The metal is aluminium.</em></u>
<u><em></em></u>
Answer:
B
Explanation:
The attraction is stronger when the magnet is closer so moving it away would decrease the strength.
I think radiation and energy transfer!
