Answer:
OB
Explanation:
it protects civil rights and liberties by striking down laws that violate the Constitution.
Answer: a: reactants Na-2 Cl-2
Products: Na-2 Cl-2;
b: reactants P-1 Cl-13 H-6 Products P-1 H-6 Cl-13
c: reactants P-4 H-12 O-16
Products H-12 P-4 O-16
Explanation: since these equations are balanced the atoms on of element on the reactants side will be same as the atoms of the same element of the product side
<span>Propane is C3H8
The balanced equation is:
C3H8 + 5 O2 --> 3 CO2 + 4 H2O
From the balanced equation you can see that for each mole of C3H8 you obtain 4 moles of H2O.
moles H2O = 5.0 moles C3H8(4 moles H2O/1 mole C3H8) = 20 moles H2O formed
Use Avogadro's number to find the number of molecules.
molecules H2O = 20 moles H2O(6.02 x 10^23 molecules/1 mole) = 1.20 x 10^25 H2O molecules</span><span>

Answer is: an atom in a pure metal that's face-centered cubic has 12 neighbor atoms.
Fce-centered cubic has eight atoms at each corner of the cube and six atoms at each face of the cube.
Metals that possess face-centered cubic structure are copper (Cu), aluminum (Al), silver (Ag) and gold (Au).
There is three types of cubic cell:
1) simple cubic unit cell.
2) body-centered cubic unit cell.
3) face-centered cubic-unit cell.
