Answer:
a mole of sodium atoms contains more atoms than a mole f potassium atoms
Explanation:
Answer: 27 grams of Be
Explanation: Berylium has a molar mass of 9.0 grams/mole
(9.0 grams/mole)*(3 moles Be) = 27 grams Be
The process or state of breaking or being broken into small or separate parts.
Answer: The equilibrium concentration of CO at 1000 K is 0.016 M , the equilibrium concentration of at 1000 K is= 0.033 M and the equilibrium concentration of at 1000 K is 0.139 M
Explanation:
Initial concentration of
Initial concentration of
The given balanced equilibrium reaction is,
Initial conc. 0.1550 M 0.172 M 0 M
At eqm. conc. (0.1550-x) M (0.172-x) M (x) M
The expression for equilibrium constant for this reaction will be,
we are given :
Now put all the given values in this expression, we get :
Thus the equilibrium concentration of CO at 1000 K is= (0.1550-x) M =(0.1550-0.139) M = 0.016 M
Thus the equilibrium concentration of at 1000 K is= (0.172-x) M =(0.172-0.139) M = 0.033 M
Thus the equilibrium concentration of at 1000 K is= x M = 0.139 M
Answer:
B. only one copy of the field in memory
Explanation:
A static method is sort of a description of a class but is not part of the objects that it generates. Crucial: A program may perform a static method without constructing an object first! All other functions (those not static) only occur when they're member of an object. Thus it is necessary to build an object before they could be executed.
Therefore, when an static field is declared static, there will be:
B. only one copy of the field in memory
