Which of the following is a distinguishing difference between rocks and minerals?
A. Minerals are aggregates of different rocks and elements.
B. Minerals have specific chemical compositions, but rocks do not.
C. Crystals are a type of rock and granite is a type of mineral.
D. Minerals are made of rocks combined in different combinations.
Answer:
B.
Explanation:
Minerals are formed due to chemical composition by rocks are pressured into their formed from dirt and naturally hard things.
The statement that represents a distinguishing difference between rocks and minerals is as follows:
Minerals have specific chemical compositions, but rocks do not.Thus, the correct option for this question is B.
What is the difference between rocks and minerals?A mineral is a naturally occurring substance with distinctive chemical and physical properties, composition, and atomic structure. Rocks are generally made up of two or more minerals, mixed up through geological processes.
Minerals are definitely formed due to chemical composition by rocks being pressured into their formation from dirt and naturally hard things. A rock is an inorganic and a solid naturally-formed substance without any chemical composition or atomic structure.
A mineral is also a solid, inorganic, substance as that like a rock which has a definite crystalline structure as well as chemical composition. Rocks form, break down and move through the rock cycle.
Therefore, the correct option for this question is B.

Solid potassium chlorate breaks into potassium chloride and oxygen gas when heated up to high temperature. This is an example of a/an _______ reaction.
Answer:
es correcto bro claro eres un crak
Answer:
Decomposition Reaction
Explanation:
You can determine the type of reaction by writing out a balanced equation.
Solid Potassium Chlorate: KClO3
Potassium Chloride: KCl
Oxygen Gas: O2
Balanced Equation: 2KClO3 -> 2KCl + 3O2
By definition, a decomposition reaction is when a single substance decomposes into two more simpler substances. AB -> A + B
Because the solid potassium chlorate is breaking into two substances, potassium chloride and oxygen gas, it is a decomposition reaction.
calculate the volume occupied by 10g of propane gas, under normal conditions of temperature and pressure
Answer:
5.5 L
Explanation:
First we convert 10 g of propane gas (C₃H₈) to moles, using its molar mass:
10 g ÷ 44 g/mol = 0.23 molThen we use the PV=nRT formula, where:
P = 1 atm & T = 293 K (This are normal conditions of T and P)n = 0.23 molR = 0.082 atm·L·mol⁻¹·K⁻¹V = ?1 atm * V = 0.23 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 293 K
V = 5.5 LHow many moles of water are contained in 3.58 x 10^24 molecules? 6.022

Which structures join with the cell’s membrane during exocytosis?
Answer:Exocytosis is also used to integrate new proteins into the cell membrane. In this process, the new protein is formed inside the cell, and migrates to phospholipid bilayer of the vesicle. The vesicle, containing the new protein as a part of the phospholipid bilayer, fuses with the cell membrane.

How many pounds of ice are required to absorb 4900 kJ of heat as the ice melts? The heat of fusion of water is 0.334 kJ/g.
Answer:
m = 32.34 pounds of ice.
Explanation:
In this case we need to use the following expression of heat:
q = m * ΔHf (1)
Where:
q: heat absorbed in J or kJ
m: mass of the compound in g
ΔHf: heat of fusion of the water in kJ/g
We are asked to look for the mass of ice in pounds, so after we get the grams, we need to convert the grams to pounds, using the following conversion:
1 pound --------> 453.59 g (2)
So, we have the heat and heat of fusion, from (1) let's solve for the mass, and then, using (2) the conversion to pounds:
q = m * ΔHf
m = q / ΔHf
m = 4900 / 0.334 = 14,670.66 g of ice
Now, the conversion to pounds:
m = 14,670.66 g * 1 pound/453.59 g
m = 32.34 pounds of ice.Hope this helps

Explanation:
how many atoms of alumminum are in 3.9 mol of aluminum
Answer:
2.35 x 10²⁴ atoms Al
Explanation:
Given 3.9 moles of aluminum (Al), determine number of aluminum atoms in that quantity of substance.
By definition a mole is the mass of substance containing one Avogadro's Number (N₀) of particles. That is, 1 mole = 1 N₀ = 6.023 x 10²³ particles*.
So, if 1 mole aluminum contains 6.023 x 10²³ atoms of aluminum then
3.9 moles Al = 3.9 moles Al x 6.023 x 10²³ atoms Al/mole Al = 2.35 x 10²⁴ atoms Al.
________________
*The complete equivalent relationship is ...
1 mole (atoms or compounds) = 6.023 x 10²³ atoms or molecules = 1 formula weight of the substance = 22.4 Liters (if in gas phase at STP conditions (0°C and 1atm pressure).
________________
Sure hope this is understandable ... if not, kick back a note. Doc
In the lab, you are given a metal ball. You measure the mass of the ball to be 28 g. You place the ball in a graduated cylinder and the water level increases from 28.2 mL to 31.4 mL. What is the density of the metal ball? (round you answer to the nearest hundredth)
Answer:
Density = 8.75ml
Explanation:
Density = Mass / Volume
In this problem ...
Mass = 28 grams
Volume = 31.4ml - 28.2ml = 32ml (water displacement also)
∴Density = mass /volume = 28g/32ml = 8.75g/ml

How do you think the artist creates sculptures that vary in color and intensity?
Answer:
Light reflected off objects. Color has three main characteristics: hue (red, green, blue, etc.), value (how light or dark it is), and intensity (how bright or dull it is). Colors can be described as warm (red, yellow) or cool (blue, gray), depending on which end of the color spectrum they fall.
Christ Crowned / Honthorst
Christ Crowned with Thorns, Gerrit van Honthorst, about 1620
Value describes the brightness of color. Artists use color value to create different moods. Dark colors in a composition suggest a lack of light, as in a night or interior scene. Dark colors can often convey a sense of mystery or foreboding.
Light colors often describe a light source or light reflected within the composition. In this painting, the dark colors suggest a night or interior scene. The artist used light colors to describe the light created by the candle flame.
Annunciation / Bouts
The Annunciation, Dieric Bouts, 1450–1455
Intensity describes the purity or strength of a color. Bright colors are undiluted and are often associated with positive energy and heightened emotions. Dull colors have been diluted by mixing with other colors and create a sedate or serious mood. In this image the artist captured both the seriousness and the joy of the scene with the dull gray stone interior and the bright red drapery.
