(A) is the correct choice
As we increase the surface area of the reactants, we increase the rate of reaction.
Increasing the surface area of a solid reactant exposes more of its particles to attack. This results in an increased chance of collisions between reactant particles, so there are more collisions in any given time and the rate of reaction increases.
Are there any choices? Because from what the question is it seems like we need choices to help
Answer:
The speed of light, c, equals the wavelength, λ (pronounced lambda), times the frequency, ν, (pronounced noo).
c=λν
c is a constant. It is usually given as 3.00×108 m/s or 3.00×1010 cm/s rounded to three significant figures.❤
The mass number is equal to the number of protons plus the number of neutrons. From the periodic table, we can see that chromium has an atomic number of 24, which means its nucleus contains 24 protons. ... Therefore, the chromium-52 isotope contains 28 neutrons in its nucleus.
Oh man. Silver coating to dampen radiating heat is great but that, of course does not tell you the temperature of the fluid inside; I would definitely add a small thermostat somewhere around the exterior. that's the only improvement I would suggest, as a standard for all.
