Answer: B. (A 25 kg ball)
Explanation:
Since , and velocity is the same for all four balls, the ball with the greatest mass will have the greatest kinetic energy (since mass and KE are directly related). Below shows these calculations:
A. m = 5
B. m = 25
C. m = 10
D. m = 1
Asthenosphere.
This layer is the only one of the choices located inside of the Earth and is around the lithosphere and the mesosphere.
Answer:
The coefficients are 2,1,1,1
Explanation:
2HCl + Mg —> MgCl2 + H2
Answer:
liquid's heat of vaporization = 38.4 kJ/mol
Explanation:
given data
vapor pressure P1 = 6.91 mmHg
at temperature = 0 °C = 273.15 K
boiling temperature = 105 °C
solution
for vapor pressure and temperature we get here
P2 = 760.0 mmHg
T2 = 68.73°C = 378.15 K
we use here the Clausius-Clapeyron Equation that is
ln = .................1
put here value
In
solve it we get
x = 38445 J/mol
liquid's heat of vaporization = 38.4 kJ/mol
The answer would be 5.5g because you have to subtract 8.2 minus 2.7 and you get 5.5g so basically the answer is C.
