Answer:
Deformation of heat and pressure
Explanation:
It is deformation of heat and pressure because igneous rock is made by magma when it cools. After a long time and pressure, it will turn into sedimentary rock.
Magnetism, or more specifically electromagnetic repulsion
Answer:
V ∝ abc
Explanation:
This task is a joint variation task involving only direct proportionality:
Direct variation is one in which two variables are in direct proportionality to each other. This means that as one increases, the other variable also increases and vice - versa.
Joint variation is one in which one variable is dependent on two or more variables and varies directly as each of them.
In this exercise:
If a ∝ b and a ∝ c, then a ∝ bc
Taking the above three proportionalities,
V ∝ a ∝ b ∝ c
V ∝ a ∝ bc
V ∝ abc
Answer:
A new Dana system of classification contains 78 different classes of minerals based on composition and then further classified by type and group. To be considered a mineral, a substance must be an inorganic, naturally formed solid, with a specific chemical formula and a fixed internal structure. To test whether something is a mineral, there are several identification tests to which the substance is subjected, including its resistance to scratching, its density in comparison to water, its color, the degree of light it reflects, the color of the powdered mineral, its breakage pattern and its crystalline form.
Explanation:
We are given with
moles Ne = 0.0700 mol
PNe = 0.409 atm
T = 33°C
The reaction is
<span>NH4NO2(s) --> N2(g) + 2H2O(g)
</span>
P total = 3.93 atm
a) The volume of the container is
V = nRT/P = 0.07(0.0821)(33 + 273) / (0.409)
Solve for V
b)
The partial pressure of H2O is
PH2O = 3.93 - 0.409
Solve for PH2O
