Answer:
0.2615 g
Explanation:
Given that mass of the body = 120 lb
The conversion of lb to g is shown below as:-
1 lb = 454 g
So, 120 lb = 120*454 g = 54480 g
The substance is 
of the human body
So, Mass of that substance in the body of mass 54480 g is:-
<u>0.2615 g of that substance would be found in the body of a person weighing 120 lb.</u>
Answer:
The new pressure is 1,65 atm
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T.
(P1xV1)/T1= (P2xV2)/T2
(1,23atmx 8,46L)/267 K = (P2 x 6,98L)/ 295K
0,039 atmx L/K = (P2 x 6,98L)/ 295K
P2=(0,039 atmx L/K)x 295K/6,98L =1,65 atm
Answer:
Space junk is travelling so fast that a collision with an astronaut or a spacecraft could be disastrous.
Explanation:
Space junk orbits the Earth at speeds of about 28 000 km/h.
That's so fast that even an orbiting fleck of paint has enough kinetic energy to cause impact craters on the surface of a spacecraft. They are even more dangerous to an astronaut on a space walk.
Much of the space debris is larger and more dangerous than a fleck of paint.
One rough estimate of the amount of space debris is
<em> </em><u>Size</u><em> </em> <u>Number of objects</u>
< 1 cm 200 000 000
1 cm to 10 cm 700 000
> 10 cm 30 000
Satellites, etc. 18 000
The chances of collision are small, but any collision can be disastrous.
I don't think that the whole question is posted here, but if you are looking for a way to balance this equation, I may have the answer. I believe the balanced equation is C5H8+9O2=4H2O+5CO2. If you need the reaction type, the answer is combustion. Hope this helps you.
Fluorine has the highest. Fluorine's electronegativity is 4.0
