<span>The mass number of an ion is calculated by adding the neutrons and electrons together. In this case 159+107=266. However, since this ion has a +1 charge, you must add 1 to the electrons. This would give a total mass of 267.</span>
<span>I am sure these answers are correct cause I've checked all of them. Here they are :
1) The thing which might h</span>appen to the rest of the water is that 61% of that water leaves the ground through evapotranspiration and <span>38% will flow into the Atlantic Ocean.
</span>
2) The four states which receive drinking water from Florida are : <span> South Carolina, Georgia, Alabama, Mississippi
3) The</span> reason why people in Florida wanted to get rid of the water in certain areas is abundance of wetlands. I think there is one more, if it is acceptable I suggest you using this - frequent flooding.<span>
4) </span><span> The negative result of the changes which people made to get rid of the water is the first sign of </span>drought.
5) The thing that has been done to try and improve those mistakes was creating a tool which looked like a dam to prevent dfficulties with <span>navigating the state.
Hope that helps.</span>
Answer is: <span>de Broglie wavelength of a proton is </span>3,4·10⁻⁵ nm.
v(proton) = 0,038 · 3·10⁸ m/s.
v(proton) = 1,14·10⁷ m/s; speed of proton.
m(proton) = 1,67·10⁻²⁷ kg.
h = 6,62607004·10⁻³⁴ m²·kg/s; Planck constant.
λ(proton) = h / m(proton) · v(proton).
λ(proton) = 6,62607004·10⁻³⁴ m²·kg/s ÷ (1,67·10⁻²⁷ kg · 1,14·10⁷ m/s).
λ(proton) = 3,48·10⁻¹⁴ m · 10⁹ nm/m = 3,4·10⁻⁵ nm.
