It would be “To obey the law of conservation of mass”
dalvyx [7]3 years ago

Option D, to obey the conservation of mass.

The conservation of mass essentially states that all the atoms in a chemical reaction will still be there once the chemical reaction is complete.
Because of this, you have to balance chemical equations in order to ensure that there isn't a surplus or deficit of atoms on either side.

O.25 moles of SO₂ will contain
ad-work [718]

Explanation:

number of mole s of H

2

= 0.25 moles

number of molecules = moles * Avogadro’s Number

number of molecules = 0.25×(6.022×10

23

)

number of molecules = 1.505×10

23

single molecule of hydrogen contains two H-atoms. So,

number of atoms = 2×(1.505×10

23

) = 3.01×10

Is the state of the air in an isolated room completely specified by the temperature and the pressure? Explain.
pashok25 [27]
I think the the state <span>of the air in an isolated room is completely specified by the temperature and the pressure. Since it is isolated, the volume would be the same as the room. Gas is specified by temperature, pressure and volume. Having the values for pressure and temperature then the gas is completely specified. Hope this answers the question.</span>
