Answer:
the first one is protons and electrons the second one is protons the third one is neutrons and the forth one is also neutron
Hey there!
Molarity = 4.8/850 x 1000 =5.647mol/lit or 5.65M
Hope this helps you dear :)
Have a good day :)
H2 <span>because the smaller the gas molecule, the faster the diffusion. (the lightest molecule will diffuse the quickest)</span>
True, because the substance basically reacts to the nervous system just like the anesthetic. Which can affect your decision making, and you might experience drowsiness, slow reaction time which is very risky for the driver and his/her surroundings.
Hope this helps :)
MThe heat energy required to raise the temperature of 0.36Kg of copper from 22 c to 60 c is calculate using the following formula
MC delta T
m(mass)= 0.360kg in grams = 0.360 x1000 = 360 g
c(specific heat energy) = 0.0920 cal/g.c
delta T = 60- 23 = 37 c
heat energy is therefore= 360g x0.0920 cal/g.c x 37 c= 1225.44 cal
