The most dense one out of all of the answers would be the glass marble with a higher density than that of the golf ball and the rubber ball
Use the ideal gas law:
PV = nRT
so, T = PV / nR
n=0.5
V= 120 dm^3 = 120 L (1 dm^3 = 1 L)
R = 1/12
P = 15,000 Pa = 0.147 atm (1 pa = 9.86 10^{-6} )
Put the values:
T = PV / nR
T = (0.147) (120) / (0.5) (1/12)
T= 426 K
The earths rotation if I’m not mistaken
Answer:
A
Explanation:
Coupled reactions are reactions in which endergonic reactions obtain the energy to go forward from exergonic reactions.
When benzene diazonium chloride interacts with phenol, the para position of the phenol molecules is associated with the diazonium salt, resulting in
p-hydroxyazobenzene. The coupling reaction is the name given to this process.
Answer:
and 
Explanation:
The equation for the reaction is AgNO3(aq) + KCl(aq) ==> AgCl(s) + KNO3(aq)
With all the ions, it is
(aq) + 
(aq) + (aq) + 
(aq) ==> AgCl(s) +
and do not change, so they are the spectator ions and are removed
The ionic equation is:
(aq) + (aq) ==> AgCl(s)
