Answer:
i answered the other one in few
Explanation:
They have seven electrons in their valence shell, so halogens are very reactive.
Hope this helps! :)
Answer:
5118.50 J
Explanation:
pΔv=nRΔT ;
therefore, ΔT=PV/nR
ΔT = (6.4×10^5)(3.2×10^(-3)/1×8.314
ΔT= 2.4633×10^2 = 246.33 K
specific heat at constant pressure is given as:
c_p = 3/2R
c_p = 12.5 J/mol K
Now, substitute in equation (1)
we know that
Q=ΔU+W ;
and
W=pΔV= 6.4×10^5×3.2×10^(-3) = 2048 J
now
ΔU=CvΔT = 12.465×246.33 =3070.50 J ;
therefore
Q=3070.50+2048= 5118.50 J
Answer:
D.
Explanation:
Genetic Engineering is a huge part in manipulating a foods property. Chemical engineering mostly the science with numbers in foods.
Biology is literally the life of the food.

1. joules
2. c
3. kinetic energy
4. mass
5. heat and light
6. conduction, convection, or radiation
7. the amount of energy in the universe is constant / energy can neither be created nor destroyed
8. Law of Conservation of Energy / Impossibility of Perpetual Motion
9. F
10. The earth's core.
11. Potential energy.
12. Nice to know.
a) Sir Seymour. The kinetic energy equation has velocity squared. Increasing velocity is much more destructive..
b) Jupiter. Weight is gravity acting on mass. Gravity increases with mass. So Jupiter.
13. True.
14. Second Law of Thermodynamics describes heat flow from hot to cold objects. So, for the refrigerator to work, it needs to steadily expell hot air or objects inside won't cool as they releases heat to the surrounding air inside the refrigerator.
