Food labels can tell someone how nutrient-dense a food is. It can show calories, fat, and others. Hope that helps.
C is the correct answer.a buffer reacts with the added acid or base which can produce H+ or hydroxide ion,or a kind of removing H+ or hydroxide added to solution.remember that buffers don't prevent additional acid or base from reacting,they react with the additional themselves.the A and D are completely wrong.
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
A) <span>Particles need to collide in order to react</span>
