Answer:
Mass is the measurement of what amount of matter is contained in an object. Whereas
weight is the measurement the pull of gravity on an object.
Another way to differentiate both is Mass is measured on a balance comparing a known amount a matter of to an unknown amount of matter and weight is measured on a scale.
Conditioned stimulus is a previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response.
Answer:
carbon dioxide
methane
nitrous oxide
Explanation:
The major greenhouse gas is of course carbon dioxide (CO2) and nearly all CO2 comes from fossil fuels and land-use change. But methane (CH4) and nitrous oxide (N2O), which mostly come from agriculture and waste, are also significant GHGs and shouldn't be discounted. This diagram shows GHGs at the global level.
plz mark me as brainliest :)
answer is: O
o goes from 0 to -2, so it is the element that is reduced
hope this helps! ;)
You would use the ideal gas equation which is Pv=nRt (r=constant=8.314) and (n=moles) and once you’ve found the number of moles you’d do mass= moles* r
P=2 atmospheres (we need this in pascals)
So 2*101325= 202650pa
And we need temperature in kelvin
30+273=303c
Rearrange the ideal gas equation to find moles
n=Pv/nRt
n=202650*0.1/8.314*303
n = 8.044405595
Mass= 8.04*44(molar mass of CO2)
= 352g
If you’re American you would do this differently as I’m a 16 year old at college in the UK
You would keep the atmospheres at 2 but you would change the volume to litres =100L and you would use the atmospheres gas constant= 0.0821
n= 2*100/0.0821*303
n=8.039780836
Mass = 8.04*44
=354g
There is a slight variation in both but that is normal if you’re American use the 2nd answer
