Answer:
sodium has a lower electronegativity:)
Explanation:
Answer:
36 years
Explanation:
2 = 16 * (1/2)^n where n is the number of half lives
2/16 = (1/2)^n
1/8 = (1/2)^n
log (1/8) = log (1/2^n)
log(1/8) = n log (1/2)
log ( 1/8 ) / log(1/2) = n = 3 half lives
each half life is 12 years so 3 * 12 = 36 years
Surface runoff, its quite obvious in the picture
Answer:
ΔE = 150 J
Explanation:
From first law of thermodynamics, we know that;
ΔE = q + w
Where;
ΔE is change in internal energy
q is total amount of heat energy going in or coming out
w is total amount of work expended or received
From the question, the system receives 575 J of heat. Thus, q = +575 J
Also, we are told that the system delivered 425 J of work. Thus, w = -425 J since work was expended.
Thus;
ΔE = 575 + (-425)
ΔE = 575 - 425
ΔE = 150 J
Answer:
Hybridization: sp
Electron geometry: linear
Molecular geometry: linear
Explanation:
H₃CCCH can also be written as its Lewis structure which is shown in the figure attached. The figure shows that the central carbon atom makes a single bond with CH₃ and a triple bond with CH. This means that the hybridization of the carbon is sp and both the electron and molecular geometry are linear with an 180° bond angle.
