2H₂ + O₂ → 2H₂O
mole ratio of O₂ : H₂O is 1 : 2
∴ if moles of O₂ = 16 mol
then moles of H₂O = (16 mol × 2)
= 32 mol
I think yes because the heat from the fire will transferred to the cannon ball and it will cause something with its energy to change effect.
Answer:
Bismuth
Explanation:
In 1869 Mendeleev published his first Periodic System ending with Bismuth.
In 1871 he updated his system to end with Uranium.
<span>First divide the ionization energy by Avogadro's number to get the energy per atom of potassium;
</span>419 kj/mol / 6.023 x 10²³
= 4.19 x 10⁵ / 6.023 x 10²³ = 6.96 x 10⁻¹⁹
E = hc/λ
where lambda (λ<span>) is the wavelength, h is Planck's constant, c is the speed of light
</span>E = 6.96 x 10⁻¹⁹ j/atom<span>
h =</span>6.63x10⁻³⁴<span> Js
c = 3 x 10</span>⁸ m/s
λ = ?
λ = hc/E = (6.63x10⁻³⁴ x 3 x 10⁸ ) / 6.96 x 10⁻¹⁹ = 285.8nm = 286nm
<span>The longest wavelength of light capable of this ionization is 286nm.</span>
Heterogeneous mixtures are made of different substances that remain physically seperate. An example would be mixing sand and sugar together.
the answer would be soil
The answer is B soil
