The formula for the wavelength of a massive particle is
λ = h/p
where
λ = wavelength
h = Plank constant (6.626070040Ă—10^â’34 J*s)
p = momentum (mass times velocity)
So let's solve for momentum and from there get the mass
λ = h/p
λp = h
p = h/λ
Substitute known values and solve
p = 6.626070040Ă—10^â’34 J*s/3.45Ă—10^-34 m
p = 1.92 J*s/m
Since momentum is the product of mass and velocity, we have
p = M * V
p/V = M
So substitute again, and solve.
p/V = M
1.92 J*s/m / 6.55 m/s = M
1.92 kg*m/s / 6.55 m/s = M
1.92 kg*m/s / 6.55 m/s = M
0.293 kg = M
So the mass is 293 grams</span>
Gasoline is a mixture of compounds called hydrocarbons (compounds of hydrogen and carbon). It is obtained by purifying crude oil by fractional distillation. Gasoline is most commonly referred to as a mixture of compounds, therefore it is a mixture. Gasoline is composed of hydrocarbons combined with different concentrations of ethanol. <span>Pure substances can be either elements or compounds. </span>Mixtures<span> can be either</span>homogeneous or heterogeneous<span>. Another term for a </span>homogeneous mixture<span> is a solution. ... </span>Gasoline<span> is thus a blend of different compounds, so it is a </span>mixture<span>.</span>
Answer:
Magnetic Quantum Number (ml): ml = -l, ..., 0, ..., +l. Specifies the orientation in space of an orbital of a given energy (n) and shape (l). This number divides the subshell into individual orbitals which hold the electrons; there are 2l+1 orbitals in each subshell.
Answer:
0
Explanation:
pure elements will always possess an oxidation number of 0, regardless of their charge.
