Answer:
<h2>12 atm</h2>
Explanation:
To find the initial pressure we use the formula for Boyle's law which is
Since we are finding the initial pressure
From the question we have
We have the final answer as
<h3>12 atm</h3>
Hope this helps you
Answer:
c,e,f
Explanation:
Judging by what i tried to find out about this reaction, it seems that won't take place, though it could be wrong.
Explanation:
1
Number of nucleon =
Molarmassofnucleon
Massofatom
=
1.6726×10
−24
g/nucleon
3.32×10
−23
g
=19.8=20(approximately)
It is given that element comprises of 2 atoms
Hence,number of nucleon = 2×20=40

You have 4.70 mol H2O
There are two H atoms in 1 molecule H2O.
Therefore, there must be 2*4.70 = 9.40 mols H in 4.70 mols H2O.
How many mols O in 4.70 mols H2O? That's 4.70 mols, of course.
Said another way, you have 2 mols H for every 1 mol H2O and 1 mol O for every 1 mol H2O.
So for 50 mols H2O you have 100 mols H and 50 mol O.
