How do properties of water break down rocks?
Answer:
Explanation:
Freezing water can break rock without any change in the minerals that form the rock (physical weathering). This usually produces small particles and sand. Water with dissolved gases and other chemicals causes the minerals in rocks to be changed, leading to the deterioration of the rock (chemical weathering).
chemical weathering
Explanation:
freezing water when mix with it cause detorilation of rocks
Dos objetos presentan fuerzas eléctricas repulsivas entre sí. ¿Cómo pueden ser las cargas eléctricas de estos objetos?
Answer:
Las cargas eléctricas de los objetos son ambas positivas o son ambas negativas.
Explanation:
Si dos objetos presentan fuerzas eléctricas repulsivas entre sí, quiere decir que ambos tienen el mismo tipo de carga.
Las cargas iguales (positivo con positivo, o negativo con negativo) se repelen, mientras que las cargas diferentes (positivo con negativo) se atraen.

What determines crystal size in minerals formed by lava or magma?
Answer:
When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

Answer:
M = 0.47
Explanation:
1 - Turn grams to moles using molar mass:
16g NaOH × 1 mol NaOH / 40g NaOH = 0.4 mol NaOH
2- Turn milliliters to liters:
855mL × 1 L / 1000mL = 0.86 L
3- Use formula which is M = moles of solute / liters of solvent:
M = 0.4 mol NaOH / 0.86 L = 0.47

a. 3.77
b. 4.20
c. 1.34
d. 13.15
e. 4.68
Answer:
V1/T1=V2/T2

Option 3 13.15 is the correct answer.
What is Charles law?Charles's law exists as an experimental gas law that explains how gases tend to expand when heated. A modern statement of Charles's law exists: When the pressure on a sample of a dry gas exists held constant, the Kelvin temperature and the volume will be in direct proportion.
According to Charles law
The volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.
[tex]V1/T1=V2/T2[/tex]
Where,
[tex]V1[/tex]= first volume
[tex]V{2}[/tex] = second volume
[tex]T{1}[/tex] = first temperature
[tex]T{2}[/tex]= second temperature
Here, at constant pressure,
[tex]V1/T1=V2/T2[/tex]
[tex]V1[/tex]=4.20 L
[tex]V2[/tex]= x
[tex]T1[/tex]=321.2 K
[tex]T2[/tex]=288.4 K
Therefore, [tex]V1/T1=V2/T2[/tex]
4.20L/321.2K=x/288.4K
1211.28/321.2=x
x=3.77L
Thus option a is correct.

Two containers, illustrated below, are filled with the same amount and the same kind of ideal gas.
Which statement correctly describes the relationship between the contents of the two containers?
Container 1 particles have higher average kinetic energy and higher temperature than Container 2 particles.
Container 1 particles have lower average kinetic energy and lower temperature than Container 2 particles.
Container 1 particles have lower average kinetic energy and lower temperature than Container 2 particles.
Container 1 particles have lower average kinetic energy and higher temperature than Container 2 particles.
Container 1 particles have lower average kinetic energy and higher temperature than Container 2 particles.
Container 1 and Container 2 particles have the same average kinetic energy and the same temperature.
Container 1 and Container 2 particles have the same average kinetic energy and the same temperature.
Answer:
Container 1 particles have lower average kinetic energy and higher temperature than Container 2 particles.
Explanation:
Kinetic energy is the speed of the particles in the bottle.
As you can see in the illustration below, the patricles in Picture 2 are moving faster than the ones in Picture 1.
The tempature of Container 1 is higher because all of the particles are sitting on top of one another. Not being able to move, their pressure builds up and creates heat.

calculate the pH of a 0.10 Maqueous Ba(OH)2 solution at 25°C ?
Answer:
The pH of a 0.10 Maqueous Ba(OH)2 solution at 25°C is 13.30
Explanation:
The balanced equation is Ba(OH)2(s)→Ba2++2OH−
This indicates that the concentration is 0.2 M
We will find H+ ion concentration
As we know that
[H+][OH−]=1.0×10−14M
Given -
[OH−]=2.0×10−1M
Putting value of [OH-] in above equation we get -
[H+]=5.0×10−14M
pH=−log10[H+]
pH=−log10[5.0×10−14] = 13.30.

7. Cells often store materials like water, salts, proteins and carbohydrates in sac-like structures called A. Chloroplasts. B. Lysosomes. C. Mitochondria. D. Vacuoles.
Answer:
A
Explanation:
the chloroplast holds the water , nutrients
Answer:
[tex]\boxed {\boxed {\sf D. \ Vacuoles}}[/tex]
Explanation:
First, let's examine each answer choice.
A. Chloroplasts
These structures are only found in plant cells. They are the site of photosynthesis: the process that turns water, carbon dioxide, and light energy into glucose and oxygen.B. Lysosomes
These help remove and break down cellular waste. They contain special enzymes that allow them to digest certain molecules, bacteria, and old parts of the cell.C. Mitochondria
These are famously known as the powerhouse of the cell. They create energy from glucose and oxygen in a process called cellular respiration.D. Vacuoles
Vacuoles are sacs that store substances, including water, nutrients, and waste.Since the question asks us to pick the sac-like structures that store materials in cells, choice D: vacuoles is correct.
Cyanobacteria, also known as blue-green algae, are a kind of bacteria found in lakes. These organisms make their own food through photosynthesis. Small animals including mayfly larvae eat the cyanobacteria, and small fish such as yellow perch eat the larvae. The small fish provide food for larger fish, such as walleye.
Choose the level of the food pyramid that represents the energy role of cyanobacteria in the lake ecosystem.
Construct an explanation for why the physical properties of the inner core, outer core, and lower mantle are essential for the development of Earth's magnetic field.
Answer:
The hot temperature of inner core and outer core is responsible for the production of magnetic field.
Explanation:
The physical properties of the inner core, outer core, and lower mantle are essential for the development of Earth's magnetic field because the very high temperature of inner core is responsible for the formation of magnetic field. If the inner core is not very hot so the magnetic field will not be generated and our earth's atmosphere will not be save from the solar wind. It can be blown away by the solar wind if this magnetic field is not present so we can conclude that the physical properties of inner core and outer core is important for the production of magnetic field.
