When a substance is soluble it:
A. can dissolve any amount into the liquid.
B. can dissolve only a specific amount into the liquid, determined by its solubility.
C. can dissolve only a specific amount into the liquid, determined by the liquid's solvent point.
D. can dissolve any amount into the liquid, as long as the liquid is being heated.
When a substance is soluble it can dissolve only a specific amount into the liquid, determined by its solubility. Hence, option B is correct.
What is the solute?A solute is something being dissolved, a solvent is a thing dissolving the item, and the solution is the mixture of the two items.
Solubility is a term used to describe how readily a substance can be dissolved in a solvent to form a solution. Thus, a substance is said to be soluble if it dissolves completely in a solvent and insoluble if it doesn't dissolve or only dissolves partially.
Hence, when a substance is soluble it can dissolve only a specific amount into the liquid, determined by its solubility.

Explanation:
Two scientists work together on an experiment, but they have different hypotheses. When scientists look at the experimental results, they interpret the data in different ways and come to different conclusions. Which of the following does this situation best illustrate?
Answer:
The correct answer is option D, confirmation bias.
The correct answer is option D, confirmation bias.Confirmation bias is the tendency to interpret data in a way that confirms the already designed hypotheses.
The correct answer is option D, confirmation bias.Confirmation bias is the tendency to interpret data in a way that confirms the already designed hypotheses.As the two scientists interpret the data (or experimental results) in different ways to adhere to the different hypotheses. this is also called indicative of cognitive bias. This is also called inductive reasoning where the premise is viewed as evidence for the validity of the conclusion.

The cart starts out in position A with high potential energy, low kinetic energy, and some thermal energy. As the cart progresses into position B, the kinetic energy begins to increase and the potential energy begins to decrease; as the thermal energy increases as thermal energy from the track is transferred to the cart through friction. Once the cart reaches position C, it has high kinetic energy, low potential energy, and some thermal energy. At position D, the cart has high potential energy, low kinetic energy, and some thermal energy. The potential energy throughout is correlated to gravity, the kinetic energy is correlated to momentum, and the thermal energy is correlated to friction. The potential energy is at its maximum during position A, and its minimum at position C; the kinetic energy is at its maximum during position C, and its minimum at position A; the thermal energy is at its maximum during position B, and its minimum at position A

- ¿Cuáles serían las características del agua filtrada que evidencie el funcionamiento del filtrador?
– Consideras que volver a filtrar la misma muestra de agua ¿disminuye la turbidez del agua?,, AYUDAAAAAAAAA
El agua se purifica a partir de un proceso de filtrado. Las características que evidencian el filtrado incluyen pH normal, color cristalino, ausencia de metales pesados y/o microorganismos, etc.
Los filtros para purificar agua son dispositivos que permiten el limpiado del agua con el objetivo de convertirla apta para consumo humano.En general, los filtros para lograr la purificación del agua consisten de carbón activado, el cual se prensa con alta presión. Este dispositivo de carbón activado permite secuestrar las partículas sólidas que pasan a través del filtro, con lo cual el agua sale a través del filtro completamente purificada.Las características que permiten determinar si el agua ha sido correctamente filtrada incluyen:
El agua sale cristalina, es decir, sin ningún tipo de color que evidencie la presencia de contaminación.El pH del agua potable debe oscilar entre valores normales (6,5 a 8,5)No debe contener metales tales como plomo, arsénico o cadmio (altamente tóxicos)No debe contener microorganismosAprende más sobre este tema en:

How many moles of fluorine gas are in 54.1 grams of fluorine gas?
Answer: 2.85 moles of flourine
Explanation:
find the atomic/molar mass of flourine on your periodic table.
multiply the given mass (54.1g) by (1 mole of flourine/atomic mass of flourine)
54.1g flourine * 1mole of flourine/18.998g flourine
(g flourine) in the above equation cancel each other.
54.1/18.998 = 2.85 mole of flourine
Que instrumentos de laboratorio usaron luis y Juan?
Luis y Juan querían hacer una investigación sobre la rapidez de disolución de una pastilla efervescente en el ácido acético a temperatura caliente. Para esto, tenían que triturar la pastilla y luego utilizar solamente 15 gramos de la sustancia. Tenían que medir 50 ml de ácido acético y colocar el mismo en un recipiente donde se pueda calentar sustancias, pero que el vapor generado se libere rápido. Al agregar ambas sustancias al recipiente de vidrio, lo comenzaron a calentar. Una vez se iba calentando, agitaron las sustancias poco a poco y con mucho cuidado, tomaron los cambios en temperatura de cada 2 minutos. Al finalizar el experimento, ellos compartieron sus resultados con sus compañeros de clase.

Back injuries can be crippling and severely limit one’s function and quality of life.
How would your life be affected by a back injury?
What modifications would you have to make to your home if you were confined to a wheelchair?
Which of your hobbies and activities would be affected if you could no longer walk?
A back injury would impact literally every aspect of your life.
You would need to either install a starlit, a lift, or move to a bungalow or bottom floor apartment.
The only hobbies you would be able to complete with no modifications would be what I call stationary hobbies- when you sit and do something, for example, knitting or sewing. However, some sports can be altered to allow for those in a wheelchair to play.

Determinar los gramos de ácido clorhídrico que se requiere para preparar 500 ml de solución 0.2 M de ácido clorhídrico
Answer:
m = 3.65 gram
Explanation:
ácido clorhídrico = HCl
M = m/Mr × 1000/mL
0.2 M = m/36.5 gr/mol × 1000/500 mL
0.2 M = m/36.5 gr/mol × 2
m/36.5 gr/mol = 0.2 M/2/L
m/36.5 gr/mol = 0.1 mol
m = 36.5 gr/mol × 0.1 mol
m = 3.65 gram

D. Cesium, hydragon, lithium, sodium
Please help me guys..I need the answer ASAP!..(｡ŏ﹏ŏ)(╥﹏╥)
The incorrect grouping of elements is Argon, potassium, slicon, strontium.
What is periodic table?Periodic table is a systematic arrangement of chemical elements within the coloums and rowns on the basis of their properties.
In all options given elements belongs from the same group except the first one, beacuse in argon, potassium, silicon & strontium all are present in different groups of periodic table. As argon is present in the 18th group, potassium is present in the 1st group, silicon is present in the 14th group and strontium is present in the 2nd group of the periodic table.
Hence, correct option is (A).

molecular formula of sulphur trioxide by criss cross method
Answer:
Sulfur trioxide: SO3.
Explanation:
How I came to this conclusion:
I noticed that the compound consists of non-metals, therefore it must be a covalent compound -
meaning I use prefixes for compounds.
Sulfur is S. Simple enough. Trioxide has the prefix of tri, meaning "3". Therefore there is 3 atoms of oxygen. Combine them and I get SO3.
Don't be confused with sulfite: (SO3)2− and sulfate: (SO4)2−

Explanation:
cracks in the road: the road expand on heating
hot air balloons: Because the hot air inside the balloon bag increases in size faster than the container it stretches the bag so that it expands and displaces the colder (heavier) air outside the bag
tire bursts in hot days when filled full of air due to thermal expansion
