Answers
Answer:
C
Explanation:
Boyle's law states that "the volume of a given mass of gas is inversely proportional to its pressure at constant temperature."
Inverse proportionality means that as one quantity is increasing, the other quantity is decreasing and vice versa.
Hence, as the pressure was increased, the volume decreases accordingly in obedience to Boyle's law.
Answer:
What is TRUE about the missing volume is option C.
C. The volume will decrease due to inverse relationship of V & P
Explanation:
The given parameters of the gas are;
The initial pressure of the gas, P₁ = 2 atm
The initial volume of the gas, V₁ = 1.5 L
The final pressure of the gas, P₂ = 2 atm
Boyle's law states that, at constant temperature, the volume, 'V', of a given mass is inversely proportional to its pressure, 'P';
Mathematically, Boyle's law can be expressed as follows;
P ∝ 1/V
From which we have;
P·V = Constant
∴ P₁·V₁ = P₂·V₂
For the given gas, we get;
2 atm × 1.5 L = 6 atm × V₂
∴ V₂ = 2 atm × 1.5 L/(6 atm) = 0.5 L
Therefore, the volume decreases from 1.5 L to 0.5 L.

Define Neutralisation reaction along with examples.
Answers
Answer:
Please find the definition and example of neutralization reaction below
Explanation:
In chemistry, neutralization reaction is a type of reaction involving a base and an acid to form salt and water. In other words, when an acid and a base comes together chemically to form a salt and water, a neutralization reaction is said to occur.
For example; in a reaction between sodium hydroxide (NaOH) and hydrogen chloride (HCl) as follows:
HCl(aq) + NaOH(aq) → NaCl(s) + H2O(l)
In this neutralization reaction, the HCk is the acid while the NaOH is the base (reactants). For the products, the NaCl is the salt while H2O is water.

A 1.00 L volume of gas at 35.0 °C exerts a pressure of 85.5 kPa. What will the pressure
be at 127 °C? Assume constant volume.
Answers
Answer:
111.03kPa = P₂
Explanation:
Gay Lussac's Law states that the pressure of a gas is directly proportional to the absolute temperature when volume remains constant.
The equation is:
P₁T₂ = P₂T₁
Where P is pressure and T absolute temperature of 1, initial state and 2, final state of the gas.
P₁ = 85.5kPa
T₂ = 127°C + 273.15 = 400.15K
P₂ = ?
T₁ = 35°C + 273.15 = 308.15K
P₁T₂ = P₂T₁
85.5kPa*400.15K = P₂*308.15K
111.03kPa = P₂Write the formula for Zn+2 (SO4)-2

What is an ideal gas equation?The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
The ideal gas law fails at low temperature and high pressure because the volume occupied by the gas is quite small, so the inter-molecular distance between the molecules decreases.
Hence, the volume occupied by the molecules themselves is no longer negligible.

Answers

when population increases the amount of carbon dioxide also increases as population use oxygen and release carbon dioxide
Carbon dioxide is a major greenhouse gas. The increase in the population increases the carbon dioxide amount.
What is the relation between carbon and population?The main product released from the respiratory process of organisms, especially animals is carbon dioxide. The increase in their population will increase this product.
The increased population will increase the demand for the burning of fossil fuel, pollution, and respiration, and hence the product of these activities, carbon dioxide will increase in the atmosphere.
Therefore, the carbon dioxide will increase with an increase in the population.

How are organisms classified as Eukarya different from organisms classified as Archaea and Bacteria?
A)They are all multicellular.
B)They all produce their own food.
C) They all reproduce sexually.
D) They all have membrane-bound nuclei
Answers
Answer: D
Explanation: The Eukarya differ from the Archea and Bacteria in that their cells are eukaryotic, meaning they contain a membrane enclosed nucleus and other membrane enclosed organelles.
Eukarya is different from organisms classified as Archaea and Bacteria because Eukarya have membrane-bound nuclei. Therefore, option (D) is correct.
How does the classification of Eukarya differ from Archaea?The type of cell of the organism can be classified into three domains. First is the bacteria which have no nucleus present in cells. Then Archaea have no nucleus in the cells but they have a different cell wall than bacteria. Then Eukarya have a nucleus in them.
The domains of Archaea and Bacteria are both composed entirely of small, single-celled organisms but they also have differences. All are composed of prokaryotic cells, which are nucleus-less cells. T
All the cells in the Eukarya domain contain their genetic material or DNA within the nucleus. Four classes make up the Eukarya domain: Plantae, Fungi, Animalia, and Protista.
Therefore, the domain of the Eukarya is different from organisms classified as Archaea and Bacteria as Eukarya have membrane-bound nuclei.

describe the process to determine the limiting reactant in the example listed below:
Given 3.4 grams of x element with a molar mass of 24 g/mol and 4.2 grams of y element with a molar mass of 35 g/mol. How much of compound xy2 can be generated?
x + 2y -> xy2
Answers
The amount of the compound [tex]XY_2[/tex] that can be generated would be 11.28 grams
Stoichiometric calculationFrom the equation of the reaction, the mole ratio of X and Y is 1:1.
Mole of 3.5 grams of X = 3.4/24 = 0.1417 moles
Mole of 4.2 grams of Y = 4.2/35 = 0.12 moles
Thus, Y is the limiting reactant because it is present in a lower amount than needed.
Mole ratio of Y and [tex]XY_2[/tex] = 1:1
Equivalent mole of [tex]XY_2[/tex] = 0.12 moles
Molar mass of [tex]XY_2[/tex] = 24 + (35x2) = 94 g/mol
Mass of 0.12 moles of [tex]XY_2[/tex] = 0.12 x 94 = 11.28 grams
