Answer:
12.5 g of Li are needed in order toproduce 0.60 moles of Li₃N
Explanation:
The reaction is:
6Li(s) + N₂(g) → 2Li₃N(s)
If nitrogen is in excess, the lithium is the limiting reactant.
Ratio is 2:6
2 moles of nitride were produced by 6 moles of Li
Then, 0.6 moles of nitride were produced by (0.6 .6)/ 2 = 1.8 moles of Li
Let's convert the moles to mass → 1.8 mol . 6.94 g/ 1mol = 12.5 g of Li
The correct number of significant figures and digits is 3
The number of electrons that can be held in the second orbit are 8
Answer:
The criteria listed in order of importance are;
1) To be inflated in the event of a collision in order to protect the occupants of the front of the vehicle
2) To be able to withstand the load of the breaking force of the occupants in the front seat of the vehicle during a collision
3) To be relatively tough so as to resist being torn on impact with a sharp object
The constraints listed in order of importance are;
1) How is the model design able to sense a collision that requires the airbag to be inflated
2) The uncertainty of the load the airbag will withstand upon collision
3) The possible hazard that could be caused by the gas used to inflate the airbag
4) The usage/interaction tendency between the vehicle occupant and the airbag system
Explanation:
In order to produce an effective design, it is important to be able to foresee the possible deficiencies of an idea so as to be able to mitigate the problems before an actual incident happens.
