Answer: Internalized Crystal Structure
Explanation:
"The exact and unique arrangement of atoms, ions or ionic groups is the characteristic feature of each crystallized mineral."
- S.K. Haldar & Josip Tisljar, authors of Mineralogy and Petrology
A mineral's unique and specific crystal structure determines the physical properties such as color, hardness, density, luster, crystal form, cleavage and fracture.
Which of the following statements describe what a normative system is?
Explanation:
though the statements were not given let just give you a brief review of normative system.
A normative statement explains what should be base of the subject according to the belief through valued judgement that describes the fairness of the subject on public policy. Therefore, the unemployment rate should be lowered is a valued judgement based on the belief that it will bring economic welfare.
Normative systems, i.e., sets of norms, have two main. tions: a) to evaluate human actions, and b) to guide peop. The guidance and the evaluation based on a normativ. be good or bad.In social psychology three different normative behaviours have been identified: obedience, conformity and compliance.In the context of a normative system like law (or religion or morality), every statement of what one ought to do (or ought not to do) requires justification from a more general or basic statement. Such statements lead upward through the normative hierarchy until one reaches a foundational normative premise.

If a sample of carbon dioxide is at − 60.0 ∘C and 0.50 atm and warm to 30.0 ∘C and 0.50 atm, then there will be no phase transition in the sample is a True statement.
Phase Transition:
The three main states of matter are Solid, Liquid, and gas. A phase transition occurs from one state of matter to another when energy is supplied or cut.When energy is supplied to the molecules, solid converts to liquid, and liquid converts to gas. Then, the energy increases the speed of the molecules, the density decreases and phase transition takes place.On the other hand, when the supply of energy is stopped from the molecules, the gas turns to liquid, and liquid converts to solid. Both the temperature and pressure are in the same phase.Therefore, there will be no phase transition in the sample. Hence, it is a true statement.

A 1.50 gram sample of contain 3.32g of CO2 1.58g of N2O5 and 1.865g of H2O .Its molar mass is 102.2g/mol. Determine the emperical and molecular formulas.
The correct answer for emperical and molecular formula = C5H14N2 .
3.23 g x (12.011 / 44.0098) = 0.8815 g carbon
1.865 g x (2.016 / 18.0152) = 0.2087 g Hydrogen
1.58 g x (28.014 / 108.009) = 0.4098 g Nitrogen
1.50 g minus (0.8815 + 0.2087 + 0.4098) = 0.
Convert each element's mass to moles.
0.8815 g/12.011 g/mol = 0.0734 mol carbon
0.2087 g 1.008 g/mol = 0.207 mol Hydrogen
0.4098 g 14.007 g/mol = 0.02926 mol Nitrogen
Step three is to calculate the ratio of molar amounts expressed in the smallest, whole numbers.
0.0734 mol 0.02926 mol = 2.51 carbon
7.07 mol hydrogen = 0.207 mol 0.02926 mol
Nitrogen: 0.02926 mol = 1 Nitrogen: 0.02926 mol = 1
Doubling each value yields C = 5, H = 14.14, and N = 2, resulting in the empirical formula C5H14N2.

A carpet sells for $24.99 per square yard. What is the price of the carpet per square meter? How much will it cost to carpet an area of 1365 ft2?
The carpet sells for $24.99 per square yard, so the cost of the carpet per square meter area is $40,799.85.
What is the carpet area?The carpet area is that space in your home, which can be used for laying a carpet. It includes the thickness of the internal wall, but excludes the balcony or terrace.
Given that the price of the carpet is $24.99 per square yard, in the first step to convert the square yard to a square meter. 1 square yard = 0.836 square meters now in the second step, calculate the cost per square meter based on the relation in the above step we can write,0.836 square meters of carpet costs $24.99.
Therefore, the cost of 1 square meter of the carpet would cost of the carpet multiplied by one square meter and then divided by the unit in one square yard. From this, the price of the carpet per square meter is known. Price of the carpet per square meter = $24.99 * 1 sq meter/0.836 sq meter price of the carpet per square meter= $29.89. Now we have to find the Cost of the carpet area.
Cost of carpet area = $24.99* 1365 = $40,799.85.
Thus, the Cost of carpet area is $40,799.85.

d: gravitational force, which is a vector sum
Answer:
the net force which is a vector sum
Explanation:
The net force is the vector sum of all the forces
That is, the net force is the resultant of all the forces
The vector sum of all the forces is called as the net force. In other words, the net force is the sum of all forces. Thus, option A is correct.
What is the sum of all forces acting on an object?The mass times the acceleration equals the sum of the forces. According to the second law, the acceleration is equal to zero if the object or system is not moving. As a result, the vector forces' sum must be zero.
The net force is the result of the vector sum of all the forces acting on a body. The item is considered to be in equilibrium if the net force is equal to zero.
The process of adding two or more vectors together to create a vector sum is known as vector addition. The so-called parallelogram law lays forth the guidelines for adding two or more vectors together.

To find the amount of moles in the sample, you need to multiply the amount of atoms by Avogadro's Number. This conversion is a ratio that describes how many atoms there are per every 1 mole. It is important to arrange the ratio in a way that allows for the cancellation of units (atoms should be in the denominator). The final answer should have 3 sig figs like the given value.

The following precipitation reaction can be used to determine the amount of copper ions dissolved in solution. A chemist added 5.00 × 10−2 L of a solution containing 0.173 mol L−1 Na3PO4(aq) to a 5.00 × 10−2 L sample containing CuCl2(aq). This resulted in a precipitate. The chemist filtered, dried, and weighed the precipitate. If 1.21 g of Cu3(PO4)2(s) were obtained, and assuming no copper ions remained in solution, calculate the following: the concentration of Cu2+(aq) ions in the sample solution. the concentrations of Na+(aq), Cl−(aq), and PO43−(aq) in the reaction solution (supernatant) after the precipitate was removed.
From the stoichiometry of the reaction, 0.094 g of [tex]Cu^{2+}[/tex] is contained in the reaction.

We must note that the balanced reaction equation is the entry way into obtaining the correct stoichiometry of the reaction in order to solve the problem.
Number of moles of [tex]Na_{3}PO_{4}[/tex] = 5.00 × 10−2 L * 0.173 mol L−1 = 0.00865 moles
If 2 moles of [tex]Na_{3}PO_{4}[/tex] produces 1 mole of[tex]Cu_{3}(PO_{4}) _{2}[/tex]
