Answer:
The work done on the system is 17.75_KJ
Explanation:
To solve this question we need to know the required equations from the given variables, thus
Initial volume = 85L
Final volume = 12L
External pressure = 2.4 atm.
work done = - PΔV
2.4×(85-12) = 175.2L×atm
Converting from L•atm to KJ is given by
1 L•atm = 0.1013 kJ
(175.2 L•atm) * (0.1013 kJ / 1 L•atm)
= 17.75 kJ
The work done on the system is 17.75_KJ
Answer:
The statement true is A. A and B are isotopes of the same element.
Explanation:
Isotopes correspond to atoms of the same element with different mass numbers (A), that is to say they differ in the amount of neutrons in the nucleus. In the case of compound A it has 10 neutrons, and B has 11.
The right answer is ( D ) Movement Of Tectonic Plates
Answer:
84.63924
Explanation:
one moles equals 40.30440
Tumor cells differ from normal cells in that A) Mitosis is not regulated in tumor cells.
This is seen when tumors grow to large amounts rather quickly. Mitosis is not regulated, and therefore the cells continue to multiply and that is when we are able to see and feel a palpable cancer mass - their growth is uncontrolled.
