According to the following reaction, how much energy is released during the reaction of excess B2Hy and 18. 12 L Cl2 (Both gases are initially at SP)? The molar mass of B2H6 is 27. 67 g/mol. B2H6(8) 6 Cl2(8) › 2 BC| (g) 6 HCI(g).

56 moles of   lieter in chemistry

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
