The new volume will be 33.5 L.
Explanation:
The kinetic theory of gases indicates that the space occupied by gas molecules is directly proportional to their temperature while being inversely proportional to the pressure. Assuming the number of moles is n = 1, the equation for gases can be written as:
PV = nRT
In this equation, P stands for pressure, V represents volume, R is the gas constant, and T denotes temperature.
Given that P = 523 Torr, T = 7.50 °C = 7.50 + 273.15 = 280.65 K, and the gas constant R = 62.363 Torr L mol⁻¹K⁻¹.
Consequently, the new volume will be 33.5 L.
Answer:
Both CaCl2 and CaBr2 consist of elements (bromine and chlorine) from the same group (group 7).
Explanation:
In the periodic table, elements are arranged into groups based on their valence electron count in the outermost shell. Elements in the same group, which possess a similar number of valence electrons, typically exhibit similar chemical behaviors.
Chlorine and Bromine in CaCl2 and CaBr2 belong to group 7, known as HALOGENS, characterized by having 7 valence electrons in their outer shell.
The similarity in properties between CaCl2 and CaBr2 arises because both contain Chlorine and Bromine, leading to analogous reactions and behaviors when interacting with other compounds.
Answer:
The equation formulated by Michaelis-Menten is expressed as
v₀ = Kcat × [E₀] × [S] / (Km + [S])
in which,
Kcat denotes the experimental reaction rate constant; [S] signifies the concentration of the substrate, and
Km represents the Michaelis-Menten constant.
