1.00 mole of an ideal gas occupies a volume of 22.4 L at 0 C and 760 mmHg (STP). It is cooled to -41 C while the pressure is increased to 805 mmHg. What is the new volume of the gas in liters?
Answer:
[tex]V_2=18.0L[/tex]
Explanation:
Hello there!
In this case, according to the given information, we infer that we need the combined gas law in order to solve this problem:
[tex]\frac{P_2V_2}{T_2}} =\frac{P_1V_1}{T_1}}[/tex]
Thus, by suing the temperatures in Kelvins, we can solve for the final volume as shown below:
[tex]V_2 =\frac{P_1V_1T_2}{T_1P_2}}\\\\V_2 =\frac{(760mmHg)(22.4L)(232K)}{(273K)(805mmHg)} \\\\V_2=18.0L[/tex]

organs
glands
cells
nerves
Answer:
Organs
Explanation:
Organs such as ears which enables animals to hear, The eyes which gives vision, the nose which is responsible for smelling and perceiving odors, The skin which enables animals to feel and the taste buds which permits animals to make distinction between sweetness, bitterness, sour are collectively called the sense Organs. The nervous systems principally made of a connection of neurons allows the trasmission of signals between different body parts. The purpose served by the sense Organs and nervous systems makes it possible makes the possibility of the nervous systems working through the sense Organs possible.

What do we mean when we say atoms bond together?
Answer:
When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element.
A Compound.
Explanation:
For example, when three oxygen atoms bond together, they form a molecule of ozone (O3). If a molecule forms from atoms of two or more different elements, we call it a compound.

What is the [A-] when 50 ml of 0.1 M NaOH is added to the 100 ml solution mixture which is in 0.1 M HCl and 0.1 M acetic acid? (Ka =1.75*10-5) Lütfen birini seçin: a. 6.7*10-3M b. 1.32x10-3 M c. 3.6*10-6 d. 0.067 M e. 0.33 M
Answer:
[A⁻] = 0.067 M
Explanation:
In this case, let's see what happen in the mixture of the acid.
As we can see we have a strong acid and a weak acid, at the same concentration. so the moles would be the same:
moles HCl = moles CH₃COOH = 0.1 moles/L * 0.1 L = 0.01 moles
Now, the moles of the base would be:
moles NaOH = 0.1 * 0.050 = 0.005 moles
As the base is a strong base, it will react first with the strong acid, in this case, HCl as given:
NaOH + HCl --------------> NaCl + H₂O
i. 0.005 0.010 0 0
c. -0.005 -0.005 +0.005 +0.005
e. 0 0.005 0.005 0.005
The base reacts completely with the strong acid, leaving the CH₃COOH completely in solution, so:
CH₃COOH + NaOH -------------> CH₃COONa
i. 0.01 0 0
e. 0 0 0.01
So, the [A⁻] would be the [CH₃COONa]:
[A⁻] = 0.010 / (0.1 + .050)
[A⁻] = 0.067 MHope this helps

Thanks Hope it helps.What is the role of the producer in any food chain?
Question 1 options:
Producers turn light energy into food energy
Producers make the food that consumers eat
Without producers, consumers would starve
All of these answers are correct
Answer:
All of these answers are correct.
Explanation:
They are all correct because producers make their food(energy) through photosynthesis, they provide food to herbivores and therefore the rest of the food chain, and without them, the food chain would collapse and all the consumers would starve.

accumulation. The species escaped from these operations into the Mississippi River and its tributaries and has the potential to invade the Great Lakes. Scientists are concerned that this
species is having severe negative impacts on these areas.

What volume of solution would be needed to deliver 3.0 mg of a drug if the concentration of the drug in the solution was 3.5% (m/v)?
Show work please
Answer:
The correct answer is "85.71 mg".
Explanation:
The given values are:
Mass of drug,
= 3.0 mg
Mass percentage,
= 3.5%
As we know,
⇒ [tex]Mass \ percent = \frac{Mass \ of \ drug}{Mass \ of \ solution}\times 100[/tex]
Or,
⇒ [tex]Mass \ of \ solution = \frac{Mass \ of \ drug}{Mass \ percent}\times 100[/tex]
On substituting the values, we get
⇒ [tex]=\frac{3.0}{3.5}\times 100[/tex]
⇒ [tex]=0.8571\times 100[/tex]
⇒ [tex]=85.71 \ mg[/tex]
why do solids not diffuse
Answer:
This is because of diffusion , the movement of particles from an area of high concentration to an area of low concentration. ... This means that diffusion does not happen in solids – the particles in a solid can only vibrate and cannot move from place to place.
Answer:
Solids cannot diffuse each other because they are tightly packed and they are rigid and do not have fluidity.
one of many cells in the retina of the eye that responds to low light. VOCABULARY
Answer:
I hope this helps you!
Explanation:
The retina is the back part of the eye that contains the cells that respond to light. These specialized cells are called photoreceptors. ... The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Rods are not good for color vision.

8. If 400 mL of gas has a temperature of 75°C, then what would be the new volume if the temperature increased to 95°C?
We are given:
V₁ = 400 mL T₁ = 75°c = (273+75)K = 348K
V₂ = x mL T₂ = 95°c = (273+95)K = 368K
Deriving Boyle's Law:
here, we can see that the volume and temperature are the only variables
from the ideal gas equation:
PV = nRT
T /V = P / nR
because P, n and R are constants, P/nR is a constant value
T / V = constant
which means that the initial and final ratio of P and T will be constant, hence:
T₁ / V₁ = T₂ / V₂, this is also known as the Charles' law. what I did above was it's derivation
Finding final volume:
plugging the given values:
348/400 = 368 / x
x = 368*400 / 348
x = 422.9 mL
