Answer:
The Bohr model and all of its successors describe the properties of atomic electrons in terms of a set of allowed (possible) values. Atoms absorb or emit radiation only when the electrons abruptly jump between allowed, or stationary, states. Direct experimental evidence for the existence of such discrete states was obtained (1914) by the German-born physicists James Franck and Gustav Hertz.
Explanation:
Because its like a city when the night come the temperature drops due to lack of humidity during the day its hot and humid during the night its cold and not humid
Answer:
Super-heavy elements like 114 usually only exist for fractions of a second. ... The physicists called these magic numbers the “island of stability”, because the elements with the numbers cluster together on the periodic table, flanked on all sides by ephemeral elements that dissipate in nanoseconds.
Answer:
Dependent variable are those variables that changes with the change in variables that affects it. (IG - leo_muan)
Explanation:
Dependent variable responds or gets affected to change. They are not constant. It can be possible that dependent variable is relying on independent variable as independent variable does not change with change of any of the factor in an experiment.
Sometimes, mentioning not the units leads to insufficient data of the variables. A constant is something whose value cannot be changed and is used for comparison purpose. According to the question, Rose is constant, height is dependent variable , different types of soil are independent variable.
Answer:
34 g of NH₃ were produced in the reaction
Explanation:
N₂ (g) + 3H₂ (g) → 2NH₃ (g)
Moles of N₂ → 28 g / 28 g/m = 1 mol
Moles of H₂ → 25g / 2 g/m = 12.5 moles
Clearly, the limiting is the nitrogen.
1 mol of N₂ produced 2 moles of ammonia
So, If I have 1 mol, I'll produce the same amount
2 moles of NH₃ = Mol . Molar mass
2 m . 17 g/m = 34 g
