Answer:
atomic mass of sulfur is 32.06 g/mol
Explanation:
Answer:
So if we need to react with 88 gm. of copper 2 then at least 3-4 liters.
Explanation:
Answer is: <span>1.0×10</span>¹⁶.<span>
</span>P (power of laser) = 3,2 mW = 0,0032 W.
λ (wavelength) = 633 nm = 633 · 10⁻⁹m = 6,33·10⁻⁷m.
P = n·h·c÷λ ⇒ n = n=P·<span>λ/h</span>·<span>c.
</span>c -<span> speed of light </span><span>3⋅10</span>⁸ <span>m/s.
h - </span><span>Planck's constant - </span><span>6.63⋅10</span>⁻³⁴J·<span>s.
n - number of photons emited.
n = 0,0032W </span>· 6,33·10⁻⁷m / 6.63⋅10⁻³⁴J·s · 3⋅10⁸ m/s
n = 1·10¹⁶ 1/s.<span>

The atomic number displayed on the periodic table gives the proton number.
For example, neon is the 10th element, with 10 protons.
