Answer is: 51.047 grams <span>of sodium azide are required.

Balanced chemical reaction: 2NaN₃(s) → 2Na(s) + 3N₂<span>(g).
m(</span>N₂) = 33.0 g; mass of nitrogen,
M(N₂) = 28 g/mol; molar mass of nitrogen.
n(N₂) = 33 g ÷ 28 g/mol.
n(N₂) = 1.178 mol; amount of substance.
From chemical reaction: n(N₂) : n(NaN₃) = 3 : 2.
n(NaN₃) = 2 · 1.178 mol ÷ 3.
n(NaN₃) = 0.785 mol.
M(NaN₃) = 65 g/mol.
m(NaN₃) = n(NaN₃) · M(NaN₃).
m(NaN₃) = 0.785 mol · 65 g/mol.
m(NaN₃) = 51.047 g.
Hydrochloric acid ionisation is as follows;
HCl ---> H⁺ + Cl⁻
HCl is a strong base so there's complete dissociation of acid to H⁺ ions
The number of HCl moles is equivalent to number of H⁺ ions present
1 L of solution contains - 11.6 moles of H⁺ ions
In 35 ml number of moles - 11.6 mol/L / 1000 ml x 35 ml = 0.406 mol
This number of moles are dissolved in 500 ml
therefore molarity = 0.406 mol /500 ml x 1000 ml = 0.812 M
Yes <span>Lithium sulfide (Li2S) would have 2 lithium atoms for every sulfur atom and would form an ionic bond. Sodium oxide (Na2O) has 2 sodium atoms for every oxygen atom (same ratio) and forms an <span>ionic bond</span></span>
There is no effect on the equilibrium when sodium formate is added to a solution of formic acid for hcooh( aq) + h ( aq) right arrow choo –( aq).
Equilibrium is characterized as a state of equilibrium or a stable situation in which conflicting forces balance one another out and no changes are taking place. In terms of economics, equilibrium occurs when supply and demand are equal. When you are composed and steady, you are in an equilibrium state.
An object is considered to be in an equilibrium condition when all of the forces acting on it are in balance. If the upward forces are equal to the descending forces and the rightward forces are equal to the leftward forces, then the forces are said to be balanced. Several instances of equilibrium include a book that is open and at rest. a vehicle that is going steadily.

Explanation:
Deforestations impact on the hydrosphere would "depend on the water forms" around like following:if deformation occurs near rivers or flowing streams of water,it often introduced silt to the water which may muddy the water and settle at the bottom to raise the water level.
Hope this helped!
