Answer:
Oxidation
Explanation:
Mg loses 2e- for it to gain it's stability hence the reaction above is oxidation
note: Oxidation is the loss of electrons while reduction is the gain of electrons
Eleanor wants to show her class a comparison of melting
rates between two different solids when heat is applied. A graph would be more
suitable than a table to show her data because the she can see the trend line
of the effects of melting than the table.
Answer:
the total density of the mixture = 3.415 x 10^3 g/mL
Explanation:
given:
density of a substance is 3.4 x 10^3 g/mL
Mixing it with another substance increases the density by 1.5 x 10^1 times.
find:
What is the density of the mixture?
-------------------------------------------------
let density (a) = 3.4 x 10^3 g/mL
density(b) = 1.5 x 10^1 g/mL
since there is no specific density provided for the mixture, we then add both to increase the density,
total density = density(a) + density(b)
total density = 3.4 x 10^3 g/mL + 1.5 x 10^1 g/mL
total density = 3.415 x 10^3 g/mL
therefore,
the total density of the mixture = 3.415 x 10^3 g/mL
I’m pretty sure it is number of protons
The answer is: They have no freedom to move.
However is not completely true, as even in a solid atoms still a move a bit (vibrations).
If atoms were able to slide past each other, then we would have a liquid not a solid. Liquids "flow" but never really "break apart" this is because atoms are sliding between them, think of these as a bucket of marbles rolling down a slope.
If they are free to move in all directions, then you have a gas; that's why someone uses perfume in a room, eventually everyone smells it.
