Answer:
cytoplasm is A, Dna is C, and nucleas is B
Explanation:
De Broglie's equation is used to show that photons have both particle and wave nature. photons are quantized packets of energy. the wave nature of photons can be proven as they have a wavelength. the particle nature is given by them having both velocity and mass.
de Broglies equation is;
λ = h / p
where λ - wavelength
h - Planck's constant
p - momentum
substituting the values in the equation
p = h/λ
p = 2.20 x 10⁻²⁷ kgm/s
momentum of photon is 2.20 x 10⁻²⁷ kgm/s
If one wants to make a molar quantity of aluminum oxide from aluminum in the laboratory, the amount of aluminum needed would be 53.96 grams.
<h3>Stoichiometric problem</h3>
Aluminum and oxygen react to form aluminum oxide according to the following equation:
From the balanced equation, the mole ratio of aluminum that reacts to the aluminum oxide that is produced is 2:1.
Now, we want to produce just a molar of aluminum oxide, this means 2 moles of aluminum will be required.
Recall that: mass = mole x molar mass
The molar mass of aluminum is 26.98 g/mol.
Mass of 2 moles aluminum = 2 x 26.98
= 53.96 grams
Thus, the amount of aluminum that one would need to produce a molar aluminum oxide in the laboratory is 53.96 grams.

Answer:
An -ite or -ate ending means a polyatomic ion that includes oxygen is in the formula.
ate = one more O than -ite
Explanation:
Example:
NO2 is nitrite
NO3 is nitrate
You can see that the molecules are made of the same elements, however they have more or less of one of the elements (i.e. oxygen).
