using PV=mRT/Mr
V=(4.9×8.31×(273+20))/(24.3×101.5×10^3)
=4.84×10^-3 m^3
=4.84×10^6 mm^3
Answer:
Explorations include static electricity, magnets, electromagnets and permanent magnets. Examples of cause and effect relationships could include how the distance between objects affects strength of the force and how the orientation of magnets affects the direction of the magnetic force.
Explanation:
<span>The law of conservation of mass states that, "Mass can neither be created nor destroyed, only its form changes with respect to different forms of energy."
In any reaction, say 10 gms of water is decomposed into its constituents Hydrogen and Oxygen. But the mass remains conserved for the reaction. Although mass and energy are inter-convertible. But,the net mass/energy remains conserved i.e. the mass of products will be equal to the mass of reactants. </span>
Answer:
The reaction occurs and all H2 and O2 unite to form H20
Answer:
Explanation:
Hello!
In this case, since the Gibbs free energy of any process is related with the enthalpy change, temperature and entropy change as shown below:
For a chemical reaction it is simply modified to:
Thus, since the enthalpy of reaction is given as -304.2 kJ and the entropy as -414.2 J/K (-0.4142 kJ/K), at 775 K the Gibbs free energy of reaction turns out:
Whose result means this is a nonspontaneous reaction.
Best regards!
