Answer:
It will sink
Explanation:
The density of the water is 1 g/cm³
- Elements having less density than water will float
- Elements having more density than water will sink
We are given that the density of density of aluminum is 2.7 g/cm³ which is more than the density of the water.
Therefore, it will sink.
Hope this helps :)
Oxidation is the loss of electrons. Reduction is the gain of electrons. The oxidizing agent is reduced. The reducing agent is oxidized. Cu goes from 0 to +2, it lost electrons S went from +6 to +4, it gained electrons I went from 0 to +5, it lost electrons N went from +5 to +4, it gained electrons.
Answer:
The food coloring mixes through the hot water faster than it mixes with the cold water. This is because in hot water, thewater molecules have more energy and are moving faster than the molecules of cold water. This makes it easier for the dye to get mixed throughout the hot water.
Answer:
answer-
The relative atomic mass = 204.4
explanation:
Thallium -203 = 30%
Thallium -205 = 70%
Therefore ,
relative mass of thallium = (30×203 + 70×205)/100
relative mass of thallium = (20440)/100
relative mass of thallium = 204.40 amu
Thus,
relative atomic mass of thalium =204.4 ( to 1 decimal place)
