Answer: 186.3 g of 
will be produced from 2.50 mol of K
Explanation:
The balanced chemical reaction is:
According to stoichiometry :
2 moles of K produce = 2 moles of
Thus 2.50 moles of 
will produce=
of
Mass of 
Thus 186.3 g of will be produced from 2.50 mol of K
Answer:
8.83 moles of Hydrogen
Explanation:
We are told that 1.92 moles of H2 occupies 22.2 L at a certain pressure and temperature, and we are asked to calculate the quantity of moles of H2 are necessary to fill a container of 102.1 L. So, if the pressure and temperature are constant, then the equality expressed before 1.92 H2 moles = 22.2 L maintains. Therefore, we can calculate what is being asked as follows:
22.2 L ----- 1.92 H2 moles
102.1 L ---- x = (102.1 L × 1.92 H2 moles)/22.2 L = 8.83 H2 moles
This means that 8.83 H2 moles are necessary to fill a 102.1 L container at a certain pressure and temperature.
Because of their atom's composition. some are naturally packed closer together and stronger and more durable, while others tend to be more loose and breakable and/or weaker/less durable. also with how their atoms are composed is how the atoms interact with each other/ how they share or give or take electrons.
Answer:
The two that are true are, "this represents a pure compound in two different states" and "it represents a mixture a solid and a gas".
Explanation:
This two are concluded only from the picture and the use of uniform colors throughout the picture (Showing the same element).
