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.

How many ml of a 2.903 M NaOH solution are needed to produce 500.0 ml of a 0.3344M solution?
Answer:
About 57.60 mL.
Explanation:
We can utilize the dilution equation:
[tex]\displaystyle M_1V_1 = M_2V_2[/tex]
Where M are the molarities of the solutions and V are the volumes of the solutions.
We want to determine the volume of a 2.903 M NaOH solution to mix in order to produce 500.0 mL of a 0.3344 M solution.
Substitute and solve for V₁:
[tex]\displaystyle \begin{aligned} (2.903 \text{ M})V_1 & = (0.3344 \text{ M})(500.0 \text{ mL}) \\ \\ V_1 & = 57.60\text{ mL} \end{aligned}[/tex]

Answer:
57.6ml
Explanation:
Using dilution formula
C1V1 = C2V2
C1 = 2.903 M, V1 = ? , C2 = 0.3344 M , V2 = 500ml
2.903 × V1 = 0.3344 × 500
V1 =( 0.3344 × 500)/ 2.903
= 57.5956

A flexible vessel contains 78.00 L of gas at a pressure of 1.50 atm. Under conditions of constant temperature
and moles of gas, what is the pressure of the gas when the volume of the vessel is tripled?
The pressure of the gas when the volume of the vessel is tripled is 0.50 atm.
To find the volume of the gas, we use Boyle's law which states that for a given mass of gas at constant temperature, the pressure is inveresly proportional to its volume. This is stated mathematically as P ∝ 1/V.
So, PV = constant
P₁V₁ = P₂V₂ where P₁ = initial pressure of gas = 1.50 atm, P₂ = final pressure of gas, V₁ = initial volume of gas = 78.00 L and V₂ = final volume of gas = 3V₁ (since the volume of the gas is tripled)
So, making P₂ the subject of the formula, we have
P₂ = P₁V₁/V₂
Substituting the values of the variables into the equation, we have
P₂ = P₁V₁/V₂
P₂ = 1.50 atm × V₁/3V₁
P₂ = 1.50 atm/3
P₂ = 0.50 atm
So, the pressure of the gas when the volume of the vessel is tripled is 0.50 atm.

Answer:
My lovely people the answer is SOLAR
Explanation:
i just know
The type of energy that uses the photoelectric effect is solar energy. Therefore, the correct option is option B.
When light strikes a material surface, the photoelectric effect takes place, which results in the emission of electrons. Albert Einstein made this intriguing discovery in 1905, and it was essential in the development of quantum physics and our comprehension of the nature of light. The fundamental principle underlying the photoelectric effect is that light is made up of small energy packets known as photons. A photon's energy can be transferred to an electron in a solid or atom when it interacts with those structures. The type of energy that uses the photoelectric effect is solar energy.

d. The animals such as snakes and tortoises are called reptilians. Why?
Answer:
Explanation : Reptiles are cold blooded animals, have scales on their body (instead of hair or fur) and are usually egg laying. (certain viper types and boas give birth to live young). So that is what makes animals reptiles.
Reptiles are cold-blooded creatures that often lay eggs and have scales on their bodies rather than hair or fur. (Some types of vipers and boas give birth to live young).
Due to these reasons animals are reptiles.
What are reptiles?
Air-breathing vertebrates known as reptiles have unique skin consisting of scales, bony plates, or a combination of the two.They comprise of tortoises, turtles, lizards, snakes, and crocodiles.All of them periodically shed their skin's outer covering. The temperature of their environment affects how they function.Reptiles do not maintain a steady internal body temperature, in contrast to birds and mammals. They cannot stay warm on a chilly day without fur or feathers, and they cannot cool themselves on a hot day without sweat glands or the ability to pant. Instead, they shift as needed between the sun and the shade. They stop moving around when the weather becomes colder. Reptiles are cold-blooded due to their slow metabolic rate and heat-seeking habit.
Thus, it can be concluded that animals such as snakes and tortoises are called reptilians.

Explanation:
Please choose and answer 3 of the following 4 questions:
1. Rutherford and JJ Thompson both contributed to what we know about the structure of the atom. What experiments did they perform and how did it change what we know about the structure of the
atom? Furthermore, describe the structure of an atom using only words (no diagrams).
2. Electrons exist outside the nucleus on many different energy levels. When electrons lose energy, they emit waves that are found on the electromagnetic spectrum. What equation would you use to
find the wavelength or frequency of a wave, assuming you know the other value? What is the relationship between frequency and wavelength? What is the relationship between frequency and
energy?
3. Even though electrons move around constantly, scientists use electron configurations to give an "address" to a particular electron. What are the 4 shells that scientists use? How many electrons can
fit into each shell? How can you use the knowledge about these shells and the periodic table to determine the electron configuration of an element?
4. Suppose you know there is an element with an atomic number of 26 and a mass of 60. What do you know about this element? How many subatomic particles does it have? How can you tell?
Answer:
1. Rutherford performs the gold foil experiment while JJ Thompson performs cathode ray experiment. It was Rutherford's experiment that used positively charged alpha particles (He with a +2 charge) that were deflected by the dense inner mass of the nucleus (nucleus). The conclusion that could be drawn from this finding was that atoms were composed of an inner core that comprised the majority of the atom's mass and was positively charged in nature. The work of JJ Thompson using cathode ray tubes demonstrated that all atoms contain small negatively charged subatomic particles, also known as electrons. According to Thomson's conception of the atom, which had negatively-charged electrons buried inside a positively-charged "soup," the atom was made of plum pudding. Protons, electrons, and neutrons are the three fundamental particles that make up an atom. The protons (which are positively charged) and neutrons (which are neutrally charged) are found in the nucleus (center) of an atom (no charge). The electrons are contained inside the electron shells, which are the outermost parts of the atom (negatively charged).
2. Given that the frequency is 1/T, the equation linking wave speed, frequency, and wavelength is v=f t. The relationship between frequency and wavelength is inversely proportional. The wavelength of the wave with the highest frequency is also the shortest. When the frequency is doubled, the wavelength is cut in half. As a result, the wavelength to frequency ratio is the inverse of the frequency to wavelength ratio. When it comes to carrying energy, the frequency and amplitude of the waves are important factors to consider. The higher the frequency, the greater the amount of energy, and the larger the amplitude, the greater the amount of energy.
3. There are four shells that scientists used. First shell contains 2 electrons. Second shell consists of 8 electrons. Third shell has 18 electrons. Lastly, fourth shell has 32 electrons. 2 electrons can fit into each shell. If you want to compute an electron configuration, first split the periodic table into portions that represent the atomic orbitals, which are the locations where electrons are found. The s-block is represented by groups one and two, the d-block by groups three through twelve, the p-block by groups thirteen through eighteen, and the f-block by the two rows at the bottom.
