Answer:

Foliation is a strong, parallel alignment of coarse mica flakes and/or of different mineral bands in a metamorphic rock.

Explanation:

Foliation is most commonly prevalent in metamorphic rocks. Foliation is the parallel alignment of textural and structural features of a rock.

Differential stress plays a major role on the texture of metamorphic rocks because it forces the mineral constituent of the rocks to align parallel to each other. Foliation can occur in different ways for example a mineral like mica which is usually platy can crystallize in rocks , due to differential stress the mineral grows in such a way it remains parallel to the movement in which the part of the rock slide relative to one another and parallel to the forces applied or the mineral might grow perpendicular to the direction of the compressed stress.

Notice the foliation in the texture of gneiss .You can see the light and dark mineral found in separate or parallel layer.

Mixtures can be uniform(called _____________) an are known as solutions

Luden [163]

Answer:

mixtures can be uniform(called <u>homogeneous</u>) an are known as solutions

Explanation:

Homogeneous mixtures are mixtures with different substances but with uniform composition. E.g. Salt water solution has salt and water inside but the salt dissolves in the water to form a homogeneous mixture.

What is your calculated density of water at R.T.?

Alekssandra [29.7K]

The mass of 40 mL of water is 40 grams. Since D = m/v and mL = cm3, the density of water is 1 g/cm3. Choose a volume between 1 and 100 mL. Use your graph to find the mass.

In acidic solution, the breakdown of sucrose into glucose and fructose has this rate law: Rate = k[H⁺][sucrose]. The initial rat

yKpoI14uk [10]

In an acidic solution, the rate change if Sucrose is changed to 2.5 M will be Rate = k[H⁺][2.51M] as the initial rate of sucrose breakdown is measured in a solution that is 0.01 M H⁺.

<h3>What is the breakdown of sucrose?</h3>

Sucrose is a type of sugar that is made by adding fructose and glucose or the breakdown of fructose will be in the form of glucose and fructose always at different levels of concentration.

In the given acidic solution if the concentration of sucrose changes from 0.01 to 2.5 then both have to add to give the total rate of change in the given reaction and it will be 2.51 M.

Therefore, Rate = k[H⁺][2.51M] as the initial rate of sucrose breakdown is measured in a solution that is 0.01 M H⁺for an acidic solution, the rate change if Sucrose is changed to 2.5 M.

At 25 oC, the rate constant for the first-order decomposition of a pesticide solution is 6.40 x 10-3 min-1. If the starting conc

Ira Lisetskai [31]

Answer:

$2.11\ * 10^{-2}$ is the correct answer to the given question.

Explanation:

Given k=6.40 x 10-3 min-1.

According to the first order reaction .

The concentration of time can be written as

$[\ A\ ]\ = \ [\ A_{0}\ ] * e \ ^\ {-kt}$

Here $[\ A\ ]_{0}$ = Initial concentration.

So $[\ A\ ]_{0}= 0.0314 M$

Putting this value into the above equation.

$0.0314 \ *\ e^{6.40 x 10^{-3} \ * \ 62.0 }$

=0.211 M

This can be written as

$=\ 2.11 *\ 10^{-2}$

Explain how to separate sugar from supersaturated sugar solution<br> guys pls help

brilliants [131]

A “supersaturated” solution contains more dissolved material. supersaturated solutions lies in the temperature of the water. more sugar will dissolve in hot water than in cold. Meaning that by separating the 2, only the supersaturated sugar would dissolve leaving the regular sugar untouched.
