The dirigible Hindenburg had 3.7E6 m3 of hydrogen in its gas bags at 1.1 atm and 7°C. What was the weight of the hydrogen in pou
zepelin [54]
Assuming that the gas is ideal, we can use the ideal gas equation PV=nRT to calculate for the number of moles. Then, multiply the molar mass of the gas to obtain the mass. We do as follows:

PV = nRT
n = PV / RT
n = 1.1 atm (3.7x10^9 L) / 0.08205 L-atm/mol-K (280.15) = 177061931.3 mol H2

Mass = (177061931.3 mol H2) 18.02 g/mol ( 1 kg / 1000g) ( 2.2 lb / 1 kg ) = 7019443.21 lb H2

Diatomic hydrogen gas and diatomic nitrogen gas react spontaneously to form a gaseous product. Give the balanced chemical equati
alex41 [277]

Answer : NH_{3}

Explanation : When diatomic hydrogen gas and diatomic nitrogen gas reacts spontaneously it forms ammonia gas as the product.

we will have the following reactions; As all the reactants and products are in the gaseous state the subscript (g) is given to the molecules.

H_{2}_{(g)} + N_{2}_{(g)} ----> NH_{3}_{(g)}

But this is not a balanced equation, as on the right side of reactants we have 2 hydrogen atoms and 2 nitrogen atoms which gives the product which has one nitrogen and three hydrogen in the compound state.

So, balancing the equation, we get,

3H_{2}_{(g)} + N_{2}_{(g)} ----> 2NH_{3}_{(g)}

We multiplied 2 with the diatomic hydrogen molecule which resulted in production of 2 moles of ammonia as the product.

So, the complete balanced equation is;

3H_{2}_{(g)} + N_{2}_{(g)} ----> 2NH_{3}_{(g)}

Lady bird [3.3K]

Answer: noble gases are in reactive.

Explanation: noble gases are present in the right most corner of the periodic table in the 8th group. So their outermost shells are complete. Their boiling point, mass increases down the group. the have strong forces of interaction. their ionization energy decreases down the group
