before the lava rises to the earth's surface it's called magma. Although lava and magma are often used interchangeably, technically magma is the name for the hot molten rock (mixed with gases and mineral crystals) that collects in chambers beneath the Earth's crust.

How is the mantle different from the core?​
Pepsi [2]

Answer:The Earth's mantle is made up of semisolid rocks. ... The core consists of extremely hot metal layers instead of rock. Iron and nickel make up the outer section of the core, while the interior is almost entirely iron. The inner core is almost totally solid and shaped like a ball.

What quantity can be calculated for a solid compound, given only the formula of the compound and the periodic table of elements
gavmur [86]
When you have both of these ( The periodic table of elements and the formula of your compound) you are able to calculate the R.M.M ( Relative atomic mass) of that compound.
For example the formula of a NaCl ( Table salt ) has the elemnt Na and Cl.
We look at the atomic mass of both of these compounds
Na - 23
Cl - 35.5
R.M.M = 23 +35.5 = 58.5
Hope this helps :).

Nitric acid and nitrogen monoxide react to form nitrogen dioxide and water, like this: At a certain temperature, a chemist finds
poizon [28]

Answer:

K = 3.3

Explanation:

Nitric acid, HNO3, reacts with nitrogen monoxide, NO, to produce nitrogen dioxide, NO2 and water H2O as follows:

2HNO3(g) + NO(g) → 3NO2(g) + H2O(g)

Where equilibrium constant, K, is:

K = [NO2]³[H2O] / [HNO3]²[NO]

<em>[] is the molar concentration of each species at equilibrium.</em>

To solve this question we need to find molarity of each gas and replace these in the equation as follows:

<em>[NO2] -Molar mass NO2-46.0g/mol-</em>

18.6g * (1mol/46.0g) = 0.404mol / 7.7L = 0.0525M

<em>[H2O] -Molar mass:18.01g/mol- </em>

236.7g * (1mol/18.01g) = 13.14 moles / 7.7L = 1.707M

<em>[HNO3] -Molar mass:53.01g/mol-</em>

16.2g * (1mol/53.01g) = 0.3056 moles / 7.7L = 0.0397M

<em>[NO] -Molar mass: 30.0g/mol-</em>

11.0g * (1mol/30.0g) = 0.367 moles / 7.7L = 0.0476M

Replacing:

K = [NO2]³[H2O] / [HNO3]²[NO]

K = [0.0525M]³[1.707M] / [0.0397M]²[0.0476M]

<h3>K = 3.3</h3>
