The rms speed of a gas can be calculated using the following rule:
Vrms = sqrt ( 3RT / M) where:
R is the gas constant = 8.314
T is the temperature = 29 + 273 = 302 degrees kelvin
M is the molar mass of the gas (oxygen) = 2*16 = 32 grams = 0.032 kg
Substitute in the equation to get Vrms as follows:
Vrms = sqrt [(3*8.314*302) / (0.032)] = 485.05 meters/sec
The answer would be A be cause it is the most reasonable answer
The hydrogen bonds between molecules of hydrogen peroxide loosen as temperature rises toward the optimal point, facilitating catalase's reaction with the molecules. The enzyme denatures and its structure is affected if the temperature rises above the ideal level.
<h3>What is a catalase?</h3>
The catalase is an enzyme that is responsible for reducing hydrogen peroxide.
<h3>What does catalase do?</h3>
- This enzyme is in charge of neutralizing hydrogen peroxide through its breakdown
- It hence preserves an ideal level of the molecule in the cell that is also necessary for cellular signaling processes
<h3>Importance of catalase enzyme:</h3>
- Almost every organism that is exposed to oxygen contains the very common enzyme catalase.
- In order to prevent oxidative damage, which can happen when cells or other molecules in the body come into contact with oxidative chemicals, catalase serves as a protective barrier in live cells.

In Williamson ether synthesis, the reaction begins when the hydrogen from the alcohol's hydroxyl group contacts the halogen ion. Since the iodide ion is larger than the chloride ion, there is a larger chance of collision between it and the hydrogen atom, so butyl iodide is preferred over butyl chloride.
Also, Williamson synthesis is carried out at relatively high temperatures, around 50ºC-100º C. Ethyl iodide has a boiling point of 72.2ºC, so it will be in the liquid phase. Ethyl chloride has a boiling point of 12.3ºC so it will be in the gaseous phase, which is undesirable for this.
No, it won't. A substance will only precipitate if it is not soluble in an aqueous solution. If you look at the solubility rules, it indicates that all sulfates are soluble except for ions of Ba, Pb, Ca and Sr. Since Ag is not in the list, AgSO4 is soluble and will not precipitate.
