They both are caused by quakes in the bottom of the ocean or moves in tectonic plates, so they are caused by giant forces moving other giant land masses.

Earthquakes are when the tectonic plates hit each other and volcanic eruptions are when the plates push up against each other and release the magma below the estates crust

What is sodium + oxygen when doing ionic bonds
Marta_Voda [28]

When burning sodium (Na) in oxygen (O2), you get sodium oxide (Na2O) and/or sodium peroxide (Na2O2). At high pressures, you can additionally get sodium superoxide (NaO2).

4 Na + O2 → 2 Na2O, and then partially 2 Na2O + O2 → 2 Na2O2.

Under normal conditions, approximately 20% of the mixture is Na2O2.

6 Na + 2 O2 → 2 Na2O + Na2O2

hope it helps

elixir [45]

Answer:

Hello your question is poorly written below is the well written question

Uranium, an important component of both nuclear weapons and nuclear reactors, has two major isotopes, U-238, which has a half-life of  approximately 4.5 billion years, and U-235, which has a half-life of approximately 700 million years. Both were present in equal amounts at the time of the creation of the Earth, 4.5  billion years ago. How many years after the creation of the Earth had the amount of radiation from uranium decayed to half the amount present at the time of the creation of the Earth

Answer : 140 billion years

Explanation:

Given that :

U-238   h1/2 = 4.5 billion years

U-235   h1/2 = 700 million years

At the beginning both Isotopes where present in equal amount

Determine the T years before the amount of Uranium decays to Half

T =   ?    N'2 = N1 / 2

we know that N = No ( 1/2 )^h   where h = time / half-life time

attached below is the detailed solution of the given problem

You are determining the density of an unknown solid. You figure out the volume by water displacement. Then you weigh the solid,
WINSTONCH [101]

Answer:

The calculated density will be larger

Explanation:

The calculated density will be <u>larger</u>. Because, the volume is taken accurately, by the water displacement method. But, when we the took the mass, the water was present on the unknown solid. So, the mass of that water was added to the original mass of the solid. Hence, the mass measured was larger than the original mass. We, know from the formula of density that density is directly proportional to the mass of the object.

Density = Mass/Volume

Hence, the larger measured mass means the larger value of density.
