To calculate the atomic mass<span> of a single </span>atom<span>, add up the </span>mass<span> of protons and neutrons.
So, your answer would be A) add the number of protons and neutrons</span>
Explanation:
The initial concentrations for a mixture :
Acetic acid at equilibrium = 0.15 M
Ethanol at equilibrium = 0.15 M
Ethyl acetate at equilibrium = 0.40 M
Water at equilibrium = 0.40 M
Initially:
0.15 M 0.15 M 0.40 M 0.40 M
At equilibrium
(0.15-x)M (0.15-x) M (0.40+x) M (0.40+x) M
The equilibrium constant is given by expression
Solving for x:
x = 0.0333
The equilibrium concentrations for a mixture :
Acetic acid at equilibrium = (0.15-x)M = (0.15-0.033) M = 0.117 M
Ethanol at equilibrium = (0.15-x)M = (0.15-0.033) M = 0.117 M
Ethyl acetate at equilibrium = (0.40+x)M = (0.40+0.033) M = 0.433 M
Water at equilibrium = (0.40+x)M = (0.40+0.033) M = 0.433 M
Answer:
The rock cycle
Explanation:
The three types of rocks are related and connected through the rock cycle. Rocks are not formed independently of one another, the process of their formation are interconnected.
Igneous rocks are made from cooling and solidification of magma. These magma are derived from the melting of rocks that have been subjected to high temperature and pressure.
When igneous rocks are formed, they can follow two path ways. They either get transformed to sedimentary rocks or metamorphic rocks.
When igneous rocks are subjected to metamorphic conditions, their mineralogy is altered to form metamorphic rocks.
If igneous rocks gets weathered and broken down by agents of denudation, they end up getting transformed into sedimentary rocks.
