1. Boyle's law
2. Charles's law
3. Avogadro's law
Answers
Answer:
Charles's law states that the volume of a gas is directly proportional to the temperature of the gas, while pressure and number Of moles are kept constant (V/T = constant). All temperatures must be in kelvins when used in gas law calculations.
Boyle's law states that the volume of the gas varies inversely to the pressure on the gas, while temperature and number of moles are kept constant (PV = constant).
Avogadro's law states that the volume of a gas is directly proportional to the number of moles of the gas, while pressure and temperature are kept constant (V/n constant).
Explanation:
Charles's law says that at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. This is because "temperature" means movement of the particles. So, the greater the movement of the particles (temperature), the greater the volume of the gas. Then, Charles's law indicates that the volume is directly proportional to the temperature of the gas.
So, Charles's law states that the volume of a gas is directly proportional to the temperature of the gas, while pressure and number Of moles are kept constant (V/T = constant). All temperatures must be in kelvins when used in gas law calculations.
As the volume increases, the gas particles (atoms or molecules) take longer to reach the walls of the container and therefore collide with them fewer times per unit of time. This means that the pressure will be lower because it represents the frequency of collisions of the gas against the walls. In this way pressure and volume are related, determining Boyle's law which says:
"The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure"
So, Boyle's law states that the volume of the gas varies inversely to the pressure on the gas, while temperature and number of moles are kept constant (PV = constant).
Avogadro's Law is a gas law that relates the volume and quantity of gas at constant pressure and temperatures. This law states that the volume of a gas held at constant temperature and pressure is directly proportional to the number of moles of the gas: if the amount of gas increases, the volume will increase, and if the amount of gas decreases, the volume decreases.
Then, Avogadro's law states that the volume of a gas is directly proportional to the number of moles of the gas, while pressure and temperature are kept constant (V/n constant).
Answer:
Boyle's Law: This gas relates pressure and volume at a fixed Temperature.
Charles' Law: This gas law relates the volume of a given mass and its temperature at a fixed pressure.
Avogadro's Law: This gas law relates the volume occupied by an ideal gas and the number of moles present at a fixed temperature and pressure.Avogadro's Law
Ideal Gas Law: This law states that the volume of any gas is directly proportional to the number of moles of the gas and the temperature of the gas and is inversely proportional to the pressure of the gas.

How many liters of hydrogen gas are required to react with 3.5" liters of oxygen gas in the following reaction? 2H2(g)+O2(g) -->2H2O(g)
Answers
Answer:
7 L of H₂.
Explanation:
The balanced equation for the reaction is given below:
2H₂ + O₂ —> 2H₂O
From the balanced equation above,
1 L of O₂ required 2 L of H₂.
Finally, we shall determine the volume of H₂ required to react with 3.5 L of O₂. This can be obtained as follow:
From the balanced equation above,
1 L of O₂ required 2 L of H₂.
Therefore, 3.5 L of O₂ will require
= 3.5 × 2 = 7 L of H₂.
Thus, 7 L of H₂ is required to for the reaction.

the temperature of water
the mass of salt

Answers
Answer:
the mass of salt
Explanation:
In an experiment, we have an independent variable and dependent variable. The independent variable is the variable that is manipulated to cause changes in other variable while the dependent variable is the variable that responds to the changes made to the independent variable and is measured.
In this case of experiment, the mass of the salt is the DEPENDENT VARIABLE while the different temperatures is the INDEPENDENT VARIABLE. In a graphical representation, the independent variable is always plotted on the x-axis or horizontal axis while the dependent variable is always plotted on the y-axis or vertical axis.
Since the dependent variable is the mass of the salt, it should be plotted on the y axis.

Endothermic or Exothermic -8735kJ x mols03/kJ x gSO3/
molSO3
Answers
Answer:
Exothermic
1771 g
Explanation:
Step 1: Write the balanced thermochemical equation
2 S(s) + 3 O₂(g) ⇒ 2 SO₃(g) ΔH° = -791.4 kJ
Since ΔH° < 0, the reaction is exothermic.
Step 2: Calculate the moles of SO₃ produced when 8753 kJ of energy are released
According to the thermochemical equation, -791.4 kJ are released every 2 moles of SO₃ that are formed.
-8753 kJ × 2 mol/(-791.4 kJ) = 22.12 mol
Step 3: Calculate the mass corresponding to 22.12 moles of SO₃
The molar mass of SO₃ is 80.06 g/mol.
22.12 mol × 80.06 g/mol = 1771 g

Answers
Answer:
C it requires a specific glycoprotein for its absorption.
Out of the following statements concerning vitamin B12 the only statement which is correct- it requires a specific glycoprotein for its absorption.
Let's study some facts about vitamin B12:
Vitamin B12 is an essential vitamin found in foods such as meat, fish, and dairy. It requires a specific glycoprotein for its absorption. The body absorbs vitamin B12 from food in a two-step process.⇒First, hydrochloric acid in the stomach separates vitamin B12 from the protein that it's attached to.
⇒Second, the freed vitamin B12 then combines with a protein made by the stomach, called intrinsic factor, and the body absorbs them together.
Deficiency of Vitamin B12 leads to weakness and fatigue.Transport of B12 in extracellular fluids is dependent on three homologous carrier proteins:⇒intrinsic factor, transcobalamin (also known as transcobalamin II), and haptocorrin (also known as the R-protein or transcobalamin I).

Unknown A melts at 113- 114oC. Known compounds 3-Nitroaniline and 4-Nitrophenol both melt at 112-114 oC. If A is mixed with 3-Nitroaniline and the melting point becomes broad and depressed, what must A be __________A) 3-Nitroaniline B) 4-Nitrophenol C) Both
Answers
Answer:
C) Both
Explanation:
Whenever we mix any pure form of a compound with some other form of a compound which is not in the other standard pure state, this results in the melting point of mixture to get dispersed and it becomes broad form.
Thus, when a known compound of 3-Nitroaniline mixes with both 3-Nitroaniline and 4-Nitrophenol, the melting point of the compound becomes depressed and board.
Thus the correct option is (C).

The Earth is a closed system, meaning that very little matter, including water, ever leaves or enters the atmosphere; the water that was here billions of years ago is still here now.

Explanation:
For the first question, we can see that the pressure is constant so we apply Charles law;
V1/T1 =V2/T2
V1T2 = V2T1
V1= 4.5 L
T1= 27 + 273 = 300 K
V2= ?
T2= 127 + 273 = 400 K
V2= V1T2/T1
V2= 4.5 × 400/300
V2= 6L
For question 2, Charles law is also used;
V1/T1 =V2/T2
V1T2 = V2T1
T1= 338 K
V1= 0.480 L
T2= ?
V2= 9.2 L
T2= V2T1/V1
T2= 9.2 × 338/0.480
T2= 6478.3 K

a. hydrogen sulfide ion
b. sulfuric acid
c. dihydrogen phosphate
d. water
e. carbonate ion
Answers
Hydrogen sulfide ions, dihydrogen phosphate, and water are amphoteric. Therefore, option (a), (c), and (d) are correct.
What is amphoteric?Amphoteric can be stated as any compound that can be mixed with other compounds both as a base and an acid. Water is amphoteric as it can be transformed into a compound that can be mixed as an alkali or an acid.
Amphoterism is explaining the reactivity of a compound that indicates alkaline nature when mixed with an acid and describes acidic characteristics in an alkaline environment.
When acid reacts with water, it forms H₃O⁺ ion adding an H⁺ ion from the acid. When water is combined with a base, it donates a hydrogen H⁺ ion to the base and releases a hydroxide ion.
Besides water, there are many oxides and hydroxides are utilized in amphoterism. The substances that have both characteristics acids are proton donors and bases are proton acceptors are identified as amphoteric substances.
Therefore, HS⁻, H₂O, and H₂PO₄⁻ are amphoteric in nature.

A mechanical wave is a wave which needs a material medium for its propagation. For example sound, water waves etc . The medium required by the wave can be a solid, liquid or a gas. Empty space doesn't have any medium, so a mechanical wave cannot travel through empty space.
