Answer: 1/2L
Explanation:
Volume and pressure are changed, so use Boyle's law.
P1V1=P2V2
Convert 303.9kpa to atm by mutiplying by (1/101.3)=3atm
Plug in:
1.5(1)=3(V2)
V2=1/2 L
This makes sense since volume and pressure are inversely proportional. The pressure is increased, so the volume must decrease.
Answer:
Oxygen is more electronegative.
Explanation:
Electronegativity:
Electronegativity of an atom is its tendency to attract the electron to wards it self.
Br = 2.98
O = 3.44
Oxygen is more electronegative than bromine thus it attract electron more strongly towards itself as compared to bromine.
when an more electronegative atom combine with less electroneagtive atom partial charges are created upon them. e.g
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
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
(of a reaction or process) accompanied by or requiring the absorption of heat.
Answer:
15
Explanation:
because since the outer shell has 5 electron then add 5 and 10 to get 15
