Answer:
water occupies a large volume than lead. (Ans)
Explanation:Density= Mass/Volume
Volume=Mass/Density
For water, mass=600 gm and density=0.995 gm/cm3
so, VOLUME= (600/0.995) cm3 = 603.015 cm3 =603.015 ml
For lead, mass=600 gm and density=11.35 gm/cm3
so, VOLUME= (600/11.35) cm3 = 52.863 cm3 =52.863 ml
<span>2HCl -----> H2 + Cl2 dH = +184.6kJ/mol (equation 1 reversed)
2NH3 ------> 3H2 + N2 dH = +92.20kJ/mol ( equation 2 unchanged)
N2 + 4H2 + Cl2 ------> 2NH4Cl dH = - 628.8kJ/mol (equation 3 doubled)
--------------------------------------...
Adding up: 2HCl + 2NH3 -----> 2NHCl4 dH = -352kJ/mol
Hence HCl + NH3 --------> NH4Cl dH = -352/2 = - 176kJ/mol.</span>
Yes. arthropod are animals such as insects, crabs, lobsters etc
