Uranium, most uranium does derive from a star. However, not from our sun.
Answer:
As you go down a group on the periodic table, you get more electron shells and therefore a larger atomic radius.
Answer:
156 g
Explanation:
Let's consider the following reaction.
2 NaN₃(s) → 2 Na(s) + 3 N₂
(g)
We can find the moles of N₂ using the ideal gas equation.
P × V = n × R × T
1.50 atm × 60.0 L = n × (0.08206 atm.L/mol.K) × 305 K
n = 3.60 mol
The molar ratio of N₂ to NaN₃ is 3:2. The moles of NaN₃ are:
3.60 mol N₂ × (2 mol NaN₃ / 3 mol N₂) = 2.40 mol NaN₃
The molar mass of NaN₃ is 65.01 g/mol. The mass of NaN₃ is:
2.40 mol × 65.01 g/mol = 156 g
I would say that the reign of terror was justified because they had to strike fear in people in order to get control and they did that by executing people via guillotine
Another reason i would say that it is justified is that they had to stop the people that where supporting the revolution or the revolution would not be successful
The last reason I would say its justified is that they had to fight to get there rights and they had to fight to get they changes they needed<span />
