Lab: Plate Boundaries and Movement Lab Report.
Nastasia [14]

A Plate Boundaries and Movement Lab Report is a report that shows the records of all the data relating to the movement of Plate Boundaries and their movements.

<h3>What are Plates in this context?</h3>

A tectonic plate is also described or referred to as a Lithosperic Plate. In Geography, it is described as a slab of rock that is not shaped regularly.

In most cases, it comprises continental and oceanic lithosphere.

<h3>Why is it crucial to record the movement of plates and their boundaries?</h3>

Plate Boundaries and their movement are largely linked to volcanic activities and earthquakes. This means that they can be used to predict when any of the above-mentioned events may happen.

Copper (Cu) is often used for electrical wiring and cooking pans. However, iron (Fe) is much more common on Earth than copper. W
Sergeeva-Olga [200]
What iron gives in its abundance, it takes away in it's inability to really conduct heat and electricity well. There is enough copper around, if we are careful in its use, to make copper bottomed pots and pans. Of the three best conductors in the world (silver, gold and copper) only copper has enough around and can be inexpensively mined that we make use of it.

If you google dr. copper, you will find he is an economist as well. Copper measures the wealth of an economy by how much is used. So iron might be cheaper and more abundant, but copper will save you much more in trying to do something with it.

The number of particles in one mole of a chemical substances is 602,200,000,000,000,000,000,000 particles. What is the correct w
crimeas [40]

The correct way to write this number in scientific notation : 6.022 x 10²³

<h3>Further explanation </h3>

Scientific Notation is a standard form of writing numbers used in mathematical operations

The rules:

1. Writing order : first digit, decimal point, next digit

2. Then followed by powers of 10 (the value can be +/-)

If the value is> 10 (the power of 10 is +), the decimal point is moved to the left, to the right of the first digit

If the value is <10 ((the power of 10 is -), the decimal point is moved to the right, to the right of the first digit

I certainly didn't count the details of the number of zeros listed, but only saw the answer choices.

And the right ones are: 6.022 x 10²³

Determine whether the following statements describe chemical or physical properties: (a) Oxygen gas supports combustion. (b) Fer
sdas [7]

Explanation:

A change that does not cause any change in chemical composition of a substance is known as a physical change.

For example, mass, density, volume etc are all physical changes.

On the other hand, a change that brings change in chemical composition of a substance is known as chemical change.

For example, combustion, toxicity, reactivity etc are all chemical changes.

Hence, following statements are identified as chemical or physical changes as follows.

(a) Oxygen gas supports combustion : Chemical change

(b) Fertilizers help to increase agricultural production : Chemical change

(c) Water boils below 100^{o}C on top of a mountain : Physical change

(d) Lead is denser than aluminum : Physical change

(e) Uranium is a radioactive element : Chemical change
