Magnesium + oxygen makes Magnesium Oxide.
The big numbers are for balancing the equation.
Answer:
Au^3+(aq) +3e ------> Au(s). 1.50 V
Explanation:
When we construct the galvanic cell, our intention is to produce energy by spontaneous electrochemical reactions. In order to have a spontaneous electrochemical reaction, E°cell must be positive. The more positive the value of E°cell, the more spontaneous the reaction is.
E°cell= E°cathode - E°anode
If E°cathode= 1.50 V
E°anode= -0.25 V
E°cell= 1.50 -(-0.25)
E°cell= 1.75 V
Hence the process; Au^3+(aq) +3e ------> Au(s) yields the highest standard cell potential
Answer:
helium protons and electrons determine the atomic number and helium has the lowest
When the sugar cubes are <span>placed in water, then, the mixture will be affected by stirring the water.
By stirring the water, the sugar cubes dissolve in water. The molecules of sugar cubes interact with water molecules in the jar. But when more sugar is added to the water, there comes a saturation point when no more sugar will be dissolved and it will settle down. Then, by raising the temperature the settled sugar will be dissolved too.</span>
As the star collapses, fusion occurs in the core of the star. This process compacts atoms and if the star is sufficiently massive, stellar nucleosynthesis takes place and heavier elements are formed. If nuclear fusion is unable to prevent gravitational collapse, the star will blow itself apart as a supernova, ejecting the heavier elements into space at very high speed. So space is seeded with heavier elements, to be captured by the gravitational attraction of other celestial bodies and absorbed into solar systems.
