Sea turtles they leave them on the beach
Answer:there butt and other stuff you know what I am saying
Explanation:
In the simple cubic
unit cell, the centers of <span>eight identical particles identical particles define the corners of a cube. T</span><span>he particles do touch along the cube's edges, but do not touch along the cube's </span>diagonally or through the center. There is/are eight particle (one atom) per unit cell and the coordination number is six.
There is three types
of cubic cell:<span>
1) simple cubic unit cell.
2) body-centered cubic unit cell.
3) face-centered cubic-unit cell.
The simple cubic unit cell is the
simplest repeating unit in a simple cubic structure, the edge of a
unit cell always connects equivalent points</span> <span>

Answer:
The correct answer is A
We'll have 2.0 moles of magnesium nitride produced and and excess of 2.0 moles nitrogen gas
Explanation:
Step 1: Data given
Number of moles nitrogen gas (N2) = 4.0 moles
Number of moles magnesium = 6.0 moles
Step 2: The balanced equation
3Mg + N2 → Mg3N2
Step 3: Calculate the limiting reactant
For 3 molesmagnesium (Mg) we need 1 mol nitrogen gas (N2) to react, to produce 1 mol magnesium nitride (Mg3N2)
Magnesium is the limiting reactant. It will completely be consumed 6.0 moles. Nitrogen is in excess. There will react 6.0 / 3 = 2.0 moles
There will remain 4.0 - 2.0 = 2.0 moles N2
Step4: Calculate moles Mg3N2
For 3 molesmagnesium (Mg) we need 1 mol nitrogen gas (N2) to react, to produce 1 mol magnesium nitride (Mg3N2)
For 6.0 moles Mg we'll have 6.0 / 3 = 2.0 moles Mg3N2
The correct answer is A
We'll have 2.0 moles of magnesium nitride produced and and excess of 2.0 moles nitrogen gas
Answer:
The Earth's atmosphere is made up of approximately 78% nitrogen
