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.

what is the chemistry of super glue
cyanoacrylate
When cyanoacrylate polymerizes, the cyanoacrylate sticks together on an atomic level, and it becomes solid. Super Glue solidifies in all the microscopic crevices of an object that it moved into when it was a liquid, and it can form chemical bonds with any anions in the object.

The ___ variable responds to the __ variable and goes on the Y-axis.
1. Dependent, Independent
2. Independent, Dependent
3. Control, Constant
4. Constant, Control
Answer: 1. Dependent, Independent The dependent variable responds to the independent variable and goes on the Y-axis.
Explanation: The independent variable is controlled or manipulated by the experimenter. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age.The dependent variable is what you are measuring. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.
How that helps. :)
The dependent variable responds to the independent variable and goes on the Y-axis. Therefore, option A is correct.
What is dependent variable ?In mathematical modeling, statistical modeling, and experimental sciences, there are dependent and independent variables. Dependent variables are so-called because, during an experiment, their values are examined on the assumption or presumption that they are governed by the values of other variables.
the dependent variable on other measurable variables As a result of an experimental manipulation of the independent variable or variables, these variables should change.
What you track in the experiment and what is impacted by it are both considered dependent variables. The independent variable affects the dependent variable's behavior. Because it "depends" on the independent variable, it is known as a dependent variable.
Thus, option A is correct.

A chemist performs the following reaction:
PCl5 (aq) + 4H2O (l) ⟶ H3PO4 (aq) + 5HCl (aq)
If she has 26.4 g of PCl5, what mass of water should she react to use up all of the
PCl5?
Looking for an in-depth step by step, please
Answer:
9.17 g
Explanation:
1) Calculate mols of PCl5
PCl5 (aq) + 4H2O (l) ⟶ H3PO4 (aq) + 5HCl (aq)
Mass of PCl5: 26.5g
Molar Mass of PCl5 208.24g/mol
Mol of PCl5 = Mass PCl5 /Molar mass PCl5 = 26.5g / (208.24g/mol) = 0.127257011 mol
2) Calculate mols of water needed to react
Mols of H2O per 1 Mols of PCl5 = 4 (because 4 water is needed to Phosphorus pentachloride).
Mols of H2O = Mol of PCl5 * 4 = 0.127257011 * 4 = 0.509028044 mols
3) Calculate Grams of water needed to react
Mols of H2O = 0.509028044 mols
Molar Mass of H2O = 18.015 g/mol
Mass of H2O = Mols of H2O * Molar Mass of H2O
= 0.509028044 mols* 18.015 g/mol = 9.17014021 g
sf = 3
9.17 g

The Universal Space Agency wants to know the results of your Sim investigation. Write your report to the lead chemist, explaining why drops of liquid water appeared on the outside of the cold, but not the warm, soda can. Use evidence from your investigation in your explanation.
Answer:
due to warm temperature
Explanation:
Explanation:
There is water present in liquid form instead of liquid nitrogen on the outer side of the can because of the temperature present in the surrounding environment. The temperature around the can is little warm which is favourable for the water but not for the liquid nitrogen. The liquid nitrogen present in liquid state when the temperature of the surrounding is too cold. if it is warm, the liquid nitrogen starts boiling and converts into gaseous state so that's why the warmer temperature is responsible for the presence of water not the liquid nitrogen.

Explanation:
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. ... Electric charge is carried by subatomic particles. In ordinary matter, negativecharge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel and unlike attract. An object with an absence of net charge is referred to as neutral. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects.
