Ok so N2+O2=2NO and my delta h is 180.5 kJ I need to know. If I react 10 g of nitrous gas with excess oxygen how many grams of N
Westkost [7]

Answer:

21.6 grams

Explanation:

  • N₂ + O₂ → 2NO

First we <u>convert 10 g of N₂ into moles</u>, using its <em>molar mass</em>:

  • 10 g ÷ 28 g/mol = 0.36 mol N₂

Then we <u>convert 0.36 moles of N₂ into moles of NO</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:

  • 0.36 mol N₂ * \frac{2molNO}{1molN_2} = 0.72 mol NO

Finally we <u>convert 0.72 NO moles into grams</u>, using its <em>molar mass</em>:

  • 0.72 mol NO * 30 g/mol = 21.6 g

Imagine an alternate universe where the value of the Planck constant is 6.6207 x 10^-36 J*s.
Salsk061 [2.6K]

Answer:

See explanation

Explanation:

According to Louis de Broglie, matter has an associated wavelength. He was the first scientist to establish the idea of wave-particle duality or wave- particle paradox.

The display of wavelike properties by objects in the universe is dependent on the magnitude of the of the mass of the body. Small objects have a large associated wavelength and can be described completely by quantum mechanics.

A buckyball with a mass of 1.2 x 10-21 g, 0.7 nm wide, moving at 38. m/s has a very small mass and significant associated wavelength hence the system can be completely described by quantum mechanics.

Suggest two observations that would be made when rubidium is added to cold water.
tino4ka555 [31]

Answer:

1. Rubidium metal reacts very rapidly with water to form a colorless basic solution of rubidium hydroxide (RbOH) and hydrogen gas (H2).

2. Rubidium sinks because it is less dense than water. It reacts violently and immediately, with everything leaving the container. Rubidium hydroxide solution and hydrogen are formed.
