Which other element is most likely to be a nonreactive gas?
2 answers:
Answer:
Choice D. Among the choices, (krypton) is likely to be the most similar to neon and behave as a non-reactive gas.
Explanation:
Columns in the periodic table are called "groups." Elements in the same group (i.e., same column of the periodic table) tend to have similar chemical properties.
In this example, neon is in the same right-most column of the periodic table. Since neon is a non-reactive gas, it is reasonable to infer that other elements in the same column would behave similarly.
Among the choices, krypton () is the only element in the same column. Thus, krypton would be the most likely element to be a nonreactive gas.

Hello. You forgot to replace the map needed to answer that question. The map is attached below:
Answer:
B) west to east
Explanation:
The letter H on the map represents an area with high air pressure, while the letter L represents an area with low air pressure. As in the areas of lower temperature or colder the pressure is greater, the wind leaves these areas and goes towards those of higher temperature, which present less pressure. For this reason, we can say that the wind is moving from west to east.
The greater the pressure difference between the regions, the greater the wind speed, and in these situations, strong winds or winds can occur, which are given different names, depending on the location: hurricane (Caribbean), tornado (USA), typhoon (Asia).
Question: The question is incomplete. Below is the complete question and the answer;
While ethanol (CH3CH2OH is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene CH2CH2) with water vapor at elevated temperatures. A chemical engineer studying this reaction fills a 50.0 L tank at 22. °C with 24. mol of ethylene gas and 24. mol of water vapor. He then raises the temperature considerably, and when the mixture has come to equilibrium determines that it contains 15.4 mol of ethylene gas and 15.4 mol of water vapor The engineer then adds another 12. mol of water, and allows the mixture to come to equilibrium again. Calculate the moles of ethanol after equilibrium is reached the second time. Round your answer to 2 significant digits.
Answer:
Number of moles of ethanol = 11 mol
