Iron undergoes a chemical reaction called oxidation to form rust, or iron oxide. ... Copper forms a turquoise colored oxide and silver forms a black oxide. In both cases you know that a chemical reaction has taken place because of the color change.
In quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.
The heat needed to raise the temperature of 50g of substance by 15 c is calculated as follows
Heat = mc delta T
m= mass (50g)
c= specific heat capacity (0.92)
delta T= change in temperature( 15 c)
heat is therefore= 50 x 0.92 x 15 = 690
Nb: my answer has no units since the given specific heat capacity has no units
The water levels would lower, because as the moon gets farther away, it's gravitational pull decreases. Hope this helps! :)
