Sediments are almost always deposited in flat layers. Does it appear that forces in the Earth affected the rock layers in this region? What clues do you have?

Answers

Answer:

Explanation: Sediments or sedimentary rocks are formed from pre-existing rocks broken through the agents of denudation such as air, ice, water flow which carries the particles and deposits it, the accumulation of one layer on the others is called DEPOSITION. As the deposits keeps building, LITHIFICATION occurs which involves overburden pressure acting on the sediments in layers.

Note that during deposition oldest layers are below, while the younger layers are above

explain why lighting a sparkler is considered a spontaneous reaction even though it doesn't stat start spontaneously

Answers

Lighting a sparkler is considered a spontaneous reaction even though it doesn't start spontaneouslybecause it can occur by itself, or without the influence of any external forces once it is given the necessary energy needed for it to begin the reaction.
The lighting of a sparkler is a common example of a spontaneous reaction which is often given in Science textbooks and exams around the world.

A 'spontaneous reaction' in chemistry refers to a reaction that continues on its own once started, not a reaction that starts spontaneously. A sparkler, once lit, undergoes a combustion reaction that needs no additional energy input.

The term spontaneous reaction in chemistry does not mean that a reaction starts spontaneously without any trigger. It actually refers to a reaction that, once started, continues without any additional external input. In the case of a sparkler, the initial energy to start the reaction is provided by lighting the sparkler. Once lit, the combustion reaction continues on its own, making it a spontaneous reaction.

The reactants in the sparkler (often metal powders and an oxidizing agent) are in a higher energy state than the products (typically metal oxides and heat) they form during burning. This difference in energy drives the reaction forward, making it spontaneous. The overall energy of the system decreases, which aligns with the principle of thermodynamics stating that a spontaneous process leads to a decrease in the system's free energy.

What is the volume, to the nearest whole cubic inch, of a cylinder with a height of 10 inches and a radius of 8 inches? Use Pi = 3.14 and round your answer to the whole number.cubic inches

Answers

Answer:

v=2010 inches^3

Explanation:

The volume of a cylinder can be found using:

$v=\pi r^2h$

We know the height is 10, the radius is 8, and we can substitute 3.14 in for pi

v=3.14(8^2)(10)

Solve the exponent first

v=3.14(64)(10)

v=3.14(640)

v=2009.6

To the nearest whole number:

v=2010 inches^3

Which describes the polarity in a water molecule?

Answers

Answer:

The oxygen atom in a water molecule is strongly electronegative. The atoms of the water molecule are held together by covalent bonds. water has nonpolar bonds, but it has a bent shape and is therefore polar.
