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.
What are Plates in this context?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.
Why is it crucial to record the movement of plates and their boundaries?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.

Calculate the mass in grams of NaCl required to prepare 0.500 L of a 0.500 M solution.
Answer:
14.61 g NaCl
Explanation:
Molarity = moles / volume of solution (litres)
0.500 = moles / 0.500 L
moles = 0.25
Molar mass of NaCl is 58.44 g NaCl /1 mol NaCl.
0.25 moles NaCl x 58.44 g NaCl /1 mol NaCl
= 14.61 g NaCl

Explanation:
How many grams sodium bromide can be formed from 51 grams of sodium hydroxide?
Explanation:
When working with moles only, you will start by applying stoichiometry to determine how the reactants will affect your amount of products in this reaction. For this question, we will assume that other reactants are in infinite qualities, so therefore, it is the amount of aluminum that we will be concerned with. You need to figure out how much aluminum is in the specified amount of aluminum bromide, and then how much aluminum hydroxide that will be able to create. Make sure all your units cancel out!
9.24 mol AlBr3 x (1 mol Al / 1 mol AlBr3) x (1 mol Al(OH)3 / 1 mol Al) = 9.24 mol AlBr3
When you're working with mole ratios that involve grams to moles conversions, the first thing you want to do is calculate the molecular weight of each component you are being asked about. Because the question was given to you as words instead of chemical formulas, you will want to figure out the chemical formulas. For example, aluminum hydroxide is Al(OH)3 and aluminum bromide is AlBr3. To calculate molecular weight, you will want to consult a periodic table, find the molecular weight for each atom, and then calculate the correct sum of each molecular weight. Make sure you keep track of the number of each atom you have, i.e. 3 oxygen and 3 hydrogen for aluminum hydroxide.
Na = 22.990 g/mol
O = 15.999 g/mol
H = 1.008 g/mol
NaOH = 22.990 g/mol + 15.999 g/mol + 1.008 g/mol = 39.997 g/mol
Al = 26.982 g/mol
O = 15.999 g/mol
H = 1.008 g/mol
Al(OH)3 = 26.982 g/mol + (3 x 15.999 g/mol) + (3 x 1.008 g/mol) = 78.003 g/mol
Now, if you begin with an amount of NaOH in grams, you will first have to convert that to moles in order to use the mole ratio.
24 g NaOH x (1 mol NaOH / 39.997 g NaOH) = 0.600 mol NaOH
Now, you will have to account for the part of the sodium hydroxide that will be present in the aluminum hydroxide. In this case, it is the hydroxide (OH) portion of the formula. There is one mole of OH in each mole of NaOH, but there are 3 moles of OH in each mole of Al(OH)3. You will start with the 0.600 mol NaOH you know you have and then use the mole ratio.
0.600 mol NaOH x (1 mol OH / 1 mol NaOH) x (1 mol Al(OH)3 / 3 mol OH) = 0.200 mol Al(OH)3
Finally, when you are converting from grams to grams, you will have to find the molecular weight of both the reactant and the product, convert reactants in grams to reactants in moles, then use the mole ratio, then convert the moles of product back to grams of product. This time, you are concerned about the mole ratio of sodium, as that is the element that is in both chemical formulas.

A camel hump contains 12 kg of triacyclglycerols,
a) Given that there are 0.491 moles of ATP per gram of fat, how many moles of ATP could be produced by the fat in the camel hump?
______moles
b) If the hydrolysis of ATP releases 7.3 kcal/mole, how many kilocalories are produced by the utilization of the fat?
______kcal
The answer is 5892 moles of ATP will be produced from 12 kg of triacyclglycerols, and 43012 kcal energy will be generated by the utilization of the fat .
What are Triacyclglycerols ?Triacylglycerols are formed by linking fatty acids with an ester linkage to three alcohol groups in glycerol.
Triacylglycerols are the form in which fat energy is stored in adipose tissue.
A camel hump contains 12kg = 12000 gm of Triacyclglycerols
a) It is given that there are 0.491 moles of ATP per gram of fat ,
So for 12000 gm of fat in camel hump 12000 * 0.491 moles of ATP will be produced .
= 5892 moles
Therefore Answer is 5892 moles .
If Hydrolysis of ATP releases 7.3 kcal/mole
so 5892 moles will produce 5892 * 7.3 kcal
=43012 kcal energy will be generated by the utilization of the fat.

how many grams of granite at 54.1 c must be added to 467.62 of water at 21 C to make the final temp of both come out to be 29.2 C? Specific heat of granite 0.79 J/g C, specific heat of water 4.184 J/g C
Answer:
815.59
Explanation:
Assuming no heat lost to the Surrounding
Total heat lost by granite = Total heat gained by water
mc∆T of granite = mc∆T of water
m x 0.79 x (54.1 - 29.2) = 467.62 x 4.184 x (29.2 - 21.0)
m x 19.671 = 16043.48106
m = 16043.48106/19.671
= 815.59J

Nuclear changes involves changes in the composition of the nucleus of atoms with the release of large amounts of energy.
What are nuclear changes?Nuclear changes are changes which occur in the nucleus of atoms of elements.
Nuclear changes involves radioactive decays to give radiation and energy spontaneously known as radioactivity.
In this type of nuclear change no energy is required to start the reaction but large amount of energy are released.
Nuclear changes can also involve splitting of large nucleus into smaller nucleus of atoms known as nuclear fission or the formation of larger nucleus from the combination of two or more smaller nuclei known as nuclear fusion.
Energy is required to start nuclear fission and fusion but the energy released is far greater.
When compared with energy changes in chemical reactions, the energy released in nuclear reactions is far greater.
Therefore, nuclear changes involves changes in the composition of the nucleus of atoms with the release of large amounts of energy.
