Plants, animals and bacteria
The two things that characterize the practice of science are empirical evidence and <span>community consensus.
That is being able to get the evidence that proves a certain theory, hypothesis or assumption and being neutral in accepting or rejecting the evidence and the results. You should not be biased while drawing conclusions as if this happens, then these conclusions might not be exact or correct.</span>
I believe it’s 2 moles or iron
Answer:
46.004 g/mol
Explanation:
Scottish physicist Thomas Graham formulated a law known as Graham's law of effusion in 1848. He conducted an experiment and found the relationship between the rate of effusion of a gas and its molar mass as:
where,
r is the rate of effusion of a gas
M is the molar mass of the gas.
Also, r = v/t
And for two gases taking different t₁ and t₂ to effuse, the formula is:
So,
For Neon :
= 8.61 minutes
= 20.1797 g/mol
For unkown gas:
= 13.0 minutes
= ? g/mol
<u>Molar mass of unknown gas = 46.004 g/mol</u>
Answer:
h20+co2= hco3
Explanation:
so that is not a single bond so it in gread 11 so I don't study it
