What are the gas laws? (Include Boyle's law, charles's law, gay lussac's law, an avogadro's law) Could someone please summarize these for me ples? Brainliest answer also yes
Answer:
Boyle's Law: When the pressure of a gas increases, the volume of the gas will decrease as long as the temperature and amount of gas are constant.
So basically pressure is inversely proportional to Volume, when one increases, the other decreases, vice versa.
Equation: [tex]P_{1} V_{1} = P_{2} V_{2}[/tex]
Charles Law: When the temperature of a gas increases, the volume of a gas will also increase if the pressure and amount of gas are constant.
So basically Temperature and volume are directly proportional.
Equation: [tex]\frac{V_{1}}{T_{1}} = \frac{V_{2} }{T_{2} }[/tex]
Gay Lussac's Law: When the temperature of a gas increases, the pressure of a gas also increases when volume and the amount of gas remain constant.
Basically, Temperature and Pressure are directly proportional.
Equation: [tex]\frac{P_{1}}{T_{1}} = \frac{P_{2} }{T_{2} }[/tex]
Avogadro's Law: The most intuitive gas law. When you increase the amount of gas, the volume will also increase.
Meaning the moles (amount of gas) is directly proportional to volume.
Equation: [tex]\frac{V_{1} }{n_{1} } = \frac{V_{2} }{n_{2} }[/tex] (n stands for moles)
There is a combined gas law and ideal gas law but those are just the gas laws mentioned above but combined together. These should be everything.
Answer:
Boyle Law is when pressure and volume have a reverse relationship when temperature is the same.Charles law is basically when volume and temperature have a relationship when the pressure is the same.Lussac Law is I think just when I pressure and temperature is directly tied together when the volume stays the same.I dont think there is any "avogadro law", there is only pressure volume and temperature.

a sample of glucose contains 1.250x10^21 carbon atoms, how many atoms of hydrogen does it contain?
Answer:
Hydrogen = 2.5 * 10^21
Explanation:
Chemical Formula Glucose: C₆H₁₂O₆
One of the ways you could do this is to notice that for every carbon atom there are two Hydrogen atoms. You can state this more formally by using the formula to set up a ratio: 12/6 = hydrogen to Carbon
So if there are 1.250 * 10^21 Carbon atoms in the Glucose sample, then there will be twice as many hydrogen atoms.
H = 2 * 1.25 * 10^21 = 2.5 * 10^21 atoms
You could do this more formally by setting up a proportion.
6 Carbon / 12 Hydrogen = 1.25*10^21 / x Cross Multiply
6*x = 12 * 1.25*10^21 Combine the right
6x = 1.5 * 10^22 Divide by 6
x = 2.5 * 10^21

Answer:
It really depends on the situation. If you have 1000 elk and 2 wolves, they really would play a better role in killing off elk so that the elk population doesn't get over populated and diseased, causing a major population collapse. But if there were only 10 elk and 50 wolves, the wolves would play a very negative role on the population.
Hope this helps!

How many decigrams of chromium are in 3.19 x 10^23 atoms of chromium? show work
mol = 3.19 × 10^23/6.02^23
= 0.529 mol
mass = 0.529 × 52
= 27.508 g
g to decigram
= 27.508 × 10
= 275.08 decigram

A substance has a molar heat of combustion of -810.4 kj/mol. when 0.285 mol of the substance is burned in a calorimeter containing 8.60 kg of water, the increase in water temperature is:
Answer:
6.42 °C
Explanation:
Q = mcΔT
Q = energy gain/release (J)
m = mass (kg)
c = specific heat capacity (J/°C/kg)
ΔT = change in temperature (°C)
Qs = n(ΔH°c)
Qs = energy gained/released from substance (kJ)
n = moles (mol)
ΔH°c = molar heat of combustion (kJ/mol)
m = 8.60
n = 0.285
ΔH°c = -810.4
c (of water) = 4184
Qs = 0.285(-810.4)
Qs = -230.964 (or -230964 J)
Q = 230964
230964 = (8.60)(4184)ΔT
230964 = 35982.4(ΔT)
ΔT = 6.4188... °C → 6.42 °C

supose 10 atoms of carbon (c) recat with 20 atoms of oxegen (o) to from 10 molecules of carbon dioxide (co2). According to the law of conservation of matter, how many atoms are presented in this reaction?
Answer:
30
Explanation:
CO2 means that there is 1 carbon and 2 oxygens in each CO2 molecule.
If there are 10 atoms of Carbon that requires 20 atoms of oxygen.
The number of atoms present is 10 + 20 = 30 atoms of any kind present. You just need to add.
The law of conservation of matter states that matter can be neither created nor destroyed. Your friend shows you the following chemical equation: CaCO,CaO+CO, He says that because the oxygen atoms are split between two different molecules in the products, the equation does not support the law of conservation of matter. Is your friend right? Explain your answer.
Answer:
According to conservation of matter, there should be equal amounts of all elements on both the reactant and product side.
Reactant:
1 Ca
1 C
1 O
Product:
1 Ca
1 C
3 O
Therefore, your friend is right because the law of conservation of matter is not followed in this chemical equation.

Which model represents a compound with a 1:2 ratio?
Please explain your answer.
Answer:
D
Explanation:
D is the correct answer due to the fact that they way they are connected has 2 purple atoms and 1 orange one. thus would create a 1:2 ratio with 1 orange atom and 2 purple atoms.
A would create a 2:3 ratio, B wouldn't create a ratio comparable to the others, and C creates a 1:1 ratio with a few purple atoms floating around them, making all of the answers except D invalid.
In the given figures, the name of the model representing a compound with a 1:2 is figure D.
What is molar ratio?Molar ration of any compound gives idea about the ratio of the concentration of given constituents present in that compound.
In the figure A molar ratio is 2:3, in figure B molar ratio of given constituents is not given because each molecule is composed of same types of atoms, in figure C molar ratio of given constitutes particles is 1:1 and in the figure D molar ratio of constituents is 1:2. Because in figure D, two atoms of one element and 1 atom of another element is present.
Hence, figure D is correct option.

How many liters of 0.200 M sodium hydroxide do you need to titrate 0.300 L of a 0.100 M diprotic acid to the equivalence point?
The volume of the sodium hydroxide solution needed for the reaction is 0.3 L
We'll begin by writing the balanced equation for the reaction.
H₂X + 2NaOH → 2H₂O + Na₂X
From the balanced equation above, the following data were obtained:
The mole ratio of the acid, H₂X (nA) = 1The mole ratio of base, NaOH (nB) = 2From the question given above, the following data were obtained:
Molarity of base, NaOH (Mb) = 0.2 M. Volume of acid, H₂X (Va) = 0.3 L. Molarity of acid, H₂X (Ma) = 0.1 M. Volume of base, NaOH (Vb) =?MaVa / MbVb = nA / nB
(0.1 × 0.3) / (0.2 × Vb) = 1/2
0.03 / (0.2 × Vb) = 1/2
Cross multiply
0.03 × 2 = 0.2 × Vb
0.06 = 0.2 × Vb
Divide both side by 0.2
Vb = 0.06 / 0.2
Vb = 0.3 LTherefore, the volume of NaOH needed for the reaction is 0.3 L

I hope this helps
Answer:
Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. Scientific law differs from scientific theory.

Passive prostheses are:
- self-regulated
- easily corroded
- made of nanotubes
- self-powered
Passive prostheses are self-regulating, as shown in the first answer option.
We can arrive at this answer because:
Passive prostheses are devices used to replace parts of the body that were lost by an incident.These prostheses are very useful to establish balance or the aesthetics of the body, but they have no articulations and no movement mechanism, being static.This limitation allows passive prostheses not to need external regulation and to be self-regulated by fitting the body parts.
