Conservation of mass is the underlying principle of balancing equation. When we balance equation, this means that we acknowledge that before and after the chemical reaction, the elements are conserved. To balance the chemical equation, we add coefficients before each reactant and product. Here are the following answers:
Reaction 1:
<span>2Al
3ZnCl2
3Zn
2AlCl3
Reaction 2:
</span><span>4NH3
3O2
2N2
6H2O</span>
Energy = Planck's constant * Frequency
E = (6.62607004 × 10⁻³⁴<span>) * 7 * 10</span>¹⁴
E = 46.38 * 10⁻²⁰
E = 4.638 * 10⁻¹⁹ J

Mass of the bullet (m) = 8.13 g = 0.00813 kg
velocity of the bullet (v) = 1337 miles/hr
The de Broglie wavelength (∧) of an object of mass (m) travelling at a velocity (v) is given as:
∧ = h/m*v
where h = Planck's constant = 6.626 *10^-34 kgm2/s
Convert velocity from miles/hr to m/s
1 mile/hr = 0.447 m/s
1337 miles/hr = 0.447*1337 = 597.64 m/s
∧ = 6.626*10^-34 m2.Kg.s-1/0.00813 kg * 597.64 ms-1
∧ = 1.363*10^-34 m
Answer:
Filtration (The process of separating liquids and solids)
Explanation:
Filtration works best when the solute isn't dissolved in the solvent. Basically like how you can filter dirt or sand from water. The opposite of this would be if water and sugar where mixed together you cannot unmix this duo with filtration but with the example given you can use the process of filtration to rid the gasoline of sand.
