Answer:
As the two plates move apart from each other, which often occurs at a rate of several centimetres per year, molten rock wells up from the underlying mantle into the gap between the diverging plates and solidifies into new oceanic crust. Spreading centres are found at the crests of oceanic ridges.
Explanation:
I found this answer by taking notes in class
Answer:
since that's the closest option we have
10.6atm
Explanation:
Since volume is constant
P1/T1 = P2/T1
P1 =8.5atm
T1 = 59.2°C = 332.2k
T2 = 140°C = 413k
P2 = ?
8.5/332.2 = P2/413
0.026 = P2/413
P2 = 0.026 x 413
P2 = 10.74atm
Answer:17 protons
Explanation:
An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has a mass number of 35 which means it has 18 neutrons, it can also have a mass number of 37, which means it has 20 neutrons.
I believe it is a compound, seeing as compounds are basically different types of elements, only combined into one single compound. Please tell me if i'm wrong?
