Answer:
0.675 atm
513 Torr
Explanation:
Given is that, the atmospheric pressure on the surface of Venus is
6.84 X 10⁴ Pa.
1 atm (atmospheric pressure) is equal to 101325 pascal (Pa).
To convert divide the pressure value by 101325.
Pressure in atm = 
= 0.675055 atm
Rounding it off to 3 significant digits: 0.675 atm
Now, one Torr is 133.322 Pa. For conversion, divide the pressure value by 133.322.
Pressure in Torr = 
=513.04219 Torr
Rounding it off to 3 significant digits: 513 Torr
It would probably stop moving. Earth has motion and we do do. without the world moving, there would be No wind at all.
Explanation:
solid: table, biscuit
liquid: water, urine
gas: oxygen, carbon dioxide
2H2+O2→2H2O
We have to be aware that the number of atoms are the same on both reactant side and product side.
