The external expression of a mineral’s orderly internal arrangement of atoms is referred to as its crystal form
Internally, a mineral's crystal structure, or regular, repeating arrangement of atoms, reflects the chemical makeup of the mineral. A CHEMICAL FORMULA, which only lists the proportions of the various elements and groups of elements in the mineral, can be used to describe the composition of a mineral. For minerals with a narrow range of composition, the latter idea—groups of elements—comes into play. Color, hardness, luster, crystal formations, density, and cleavage are characteristics that aid geologists in determining a mineral's identity in a rock. The atomic structure of a crystal essentially determines its form, cleavage, and hardness. Chemical composition is the main determinant of color and density.

A student sets up the following equation to convert a measurement.
(The ? stands for a number the student is going to calculate.)
Fill in the missing part of this equation.
Answer:
[tex]\frac{1 m}{100 cm}[/tex]
Explanation:
The final answer has a different set of units. In particular, meters (m) changes to centimeters (cm). To make this change, you need to multiply the first value by proportions.
When writing these proportions, it is important that they are arranged in a way that allows for the cancellation of units. For instance, since m is located in the denominator, it must be located in the numerator of the conversion.
Proportion:
1 m = 100 cm
The full expression:
[tex]-1.7*10^5\frac{V}{m}[/tex] · [tex]\frac{1 m}{100 cm}[/tex] = [tex]? \frac{V}{cm}[/tex] ^As you can see, the old unit (m) cancels out and you are left with cm in the denominator.
How are air temperature and humidity related? 1 colder air can hold more water vapor than warmer air. 2 warmer air and colder air can hold the same amount of water vapor. 3 warmer air can move faster than colder air. 4 warmer air can hold more water vapor than colder air.
Warmer air can hold more water vapor than colder air.
Weather is the atmospheric conditions of a specific area over a short period of time.Precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed are all weather elements.Temperature is a measurement of the degree of coldness or hotness of a physical object (body).Humidity, on the other hand, refers to the concentration (amount) of water vapor in the air. It is high when there is a lot of water vapor in the air and low when there is little water vapor.How can humidity levels affect your home's temperature?Your home's windows are fogged with condensation. A musty odor can be detected in the air inside your home. When you breathe in, you can feel the moisture in the air. These indicators indicate that you should act quickly. Moisture levels in your home raise the overall temperature and make it feel hot.
What is Absolute Humidity & Relative Humidity?Humidity is classified into two types: absolute and relative.
The former describes the humidity present in a parcel of air without taking temperature into account, whereas the latter describes the humidity present in the air while taking temperature into account. The former defines the amount of water content by dividing the parcel's weight by its volume, whereas the latter is calculated by dividing the amount of water content present by the total capacity of the parcel of air to hold multiplied by 100. The former decreases with height, whereas the latter becomes saturated when it reaches 100%.

Write the balanced equation for the reaction of 1 mol of naoh with 1 mol of h2po4
Answer:
3 NaOH + H₃PO₄ -----> Na₃PO₄ + 3 H₂O
Explanation:
This appears to be a double-displacement reaction. In these reactions, the cation of one compound is swapped with the cation of another. Therefore, Na⁺ (from NaOH) is swapped with H⁺ (from H₃PO₄). When constructing the new compounds, you may need to alter the amount of each ion within a particular compound to to make it neutral.
New Product #1: Na₃PO₄
----------> Na⁺ and PO₄³⁻
----------> +1 + 1 + 1 + (-3) = 0
New Product #2: H₂O (or HOH)
----------> H⁺ and OH⁻
----------> +1 + (-1) = 0
Now that you know the products, you need to balance the chemical equation. An equation is balanced when there is an equal amount of each element on both sides. These amounts can be modified by adding coefficients.
The unbalanced equation:
NaOH + H₃PO₄ -----> Na₃PO₄ + H₂O
Reactants: 1 sodium, 5 oxygen, 4 hydrogen, 1 phosphorus
Products: 3 sodium, 5 oxygen, 2 hydrogen, 1 phosphorus
The balanced equation:
3 NaOH + H₃PO₄ -----> Na₃PO₄ + 3 H₂O
Reactants: 3 sodium, 7 oxygen, 6 hydrogen, 1 phosphorus
Products: 3 sodium, 7 oxygen, 6 hydrogen, 1 phosphorus
**I was having trouble balancing the equation with the reactant H₂PO₄⁻. From my experience, I believe this compound may have been mistyped. As such, I used H₃PO₄. Please let me know if the reactant was written properly**

Explain why doesn’t the total pressure increase when more gas is added to the chamber?
Pressure is inversely proportional to volume. Therefore, the effect of pressure change is opposite to the effect of volume change. So when more gas is added to the chamber the total pressure of the chamber doesn't increase.
What are the different relations between pressure and volume?As the volume changes, the concentrations and partial pressures of both reactants and products change. As the volume decreases, the reaction shifts to the reaction side with fewer gas particles.As the volume increases, the reaction shifts to the side of the reaction containing more gas particles. As the pressure increases, the equilibrium shifts towards reactions with fewer moles of gas. As the pressure decreases, the equilibrium shifts to the side of the reaction with higher moles of gas.Moreover, the pressure change in the system due to the addition of the inert gas is not limited to this.To know more about Pressure and Volume visit:

Is it possible for the entropy of both a closed system and its surroundings to decrease during the process?
Only when heat is transferred from the system to its surroundings does a closed system suffer a decrease in entropy.
Only when heat is transferred from the system to its surroundings does a closed system suffer a decrease in entropy. Every internally reversible operation in a closed system generates entropy. Entropy remains constant in an adiabatic and internally reversible process of a closed system. Isolated systems' entropy cannot diminish.
When a system is not isolated but is in contact with its surroundings, the entropy of the open system may drop, requiring a balancing rise in the entropy of the surroundings. During a process, the entropy of an isolated system constantly increases, or in the case of a reversible process, remains constant (it never decreases).

Taking into account definition of percent yield, 31.42 grams of KClO₃ are needed to produce 8.00 g of O₂.
Reaction stoichiometryIn first place, the balanced reaction is:
2 KClO₃ → 2 KCl + 3 O₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
KClO₃: 2 moles KCl: 2 molesO₂: 3 molesThe molar mass of the compounds is:
KClO₃: 122.55 g/moleKCl: 74.55 g/moleO₂: 32 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
KClO₃: 2 moles× 122.55 g/mole= 245.1 gramsKCl: 2 moles× 74.55 g/mole= 149.1 gramsO₂: 3 moles× 32 g/mole= 96 gramsPercent yieldThe percent yield is the ratio of the actual return to the theoretical return expressed as a percentage.
The percent yield is calculated as the experimental yield divided by the theoretical yield multiplied by 100%:
percent yield= (actual yield÷ theorical yield)×100
where the theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.
Percent yield for the reaction in this caseIn this case, you know:
actual yield= 8 gramstheorical yield= ?percent yield= 65%Replacing in the definition of percent yields:
65= (8 grams÷ theorical yield)×100
Solving:
theorical yield= (8 grams÷ 65)×100
theorical yield= 12.31 grams
Then, this means that you need to find the mass of KClO₃ would theoretically produce 12.31 g of O₂.
Mass of KClO₃ requiredThe following rule of three can be applied: If by reaction stoichiometry 96 grams of O₂ are produced by 245.1 grams of KClO₃, 12.31 grams of O₂ are produced by how much mass of KClO₃?
[tex]mass of KClO_{3} =\frac{12.31 grams of O_{2}x245.1 gramsof KClO_{3} }{96 grams of O_{2}}[/tex]
