What type of foliation results from the parallel alignment of abundant, coarse-grained, mica flakes in a metamorphic rock?
1 answer:
Answer:
Schistosity
Explanation:
Firstly, foliation is dominantly found in Metamorphic rocks and is said to be the parallel alignment of textural and structural features of rocks.
Differential stress is one major factor that contributes to the texture of metamorphic rocks. Differential stress can flattened the rocks constituents. Generally, planar texture rocks are said to be foliated.
Schistosity is a kind of foliation present in phyllite and Schist rocks that is characterize by coarse grained crystal due to the parallel alignment of platy minerals like mica, biotite and muscovite.
The picture above shows a schist rocks. The most visible way to recognize schistose texture is the visible platy minerals that depicts planar alignment.

Answer: The empirical formula for the given compound is
Explanation:
The chemical equation for the combustion of compound having carbon and hydrogen follows:
where, 'x' and 'y' are the subscripts of carbon and hydrogen respectively.
We are given:
Mass of
We know that:
Molar mass of carbon dioxide = 44 g/mol
For calculating the mass of carbon:
In 44 g of carbon dioxide, 12 g of carbon is contained.
So, in 22.0 g of carbon dioxide, of carbon will be contained.
For calculating the mass of hydrogen:
Mass of hydrogen = Mass of sample - Mass of carbon
Mass of hydrogen = 7.0 g - 6 g
Mass of hydrogen = 1.0 g
To formulate the empirical formula, we need to follow some steps:
Step 1: Converting the given masses into moles.
Moles of Carbon =
Moles of Hydrogen =
Step 2: Calculating the mole ratio of the given elements.
For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 0.5 moles.
For Carbon =
For Hydrogen =
Step 3: Taking the mole ratio as their subscripts.
The ratio of Fe : C : H = 1 : 2
Hence, the empirical formula for the given compound is
<u>Answer:</u>
211.9 J
<u>Explanation:</u>
The molecules of water release heat during the transition of water vapor to liquid water, but the temperature of the water does not change with it.
The amount of heat released can be represented by the formula:
where = heat energy,
= mass of water and
= latent heat of evaporation.
The latent heat of evaporation for water is and the mass of the water is
.
The amount of heat released in this process is:
211.9 J
