Answer:
The correct answer is option a.
Explanation:
Diffusion flux is defined as movement of mas of atoms diffusing through the unit area in per unit time.It measured in (
).
J = diffusion flux
A = Unit area A through which atoms moves.
M = mass of atoms passes in t interval of time.
Well, if you are moving forward in a direction, then your velocity is your speed with the direction you are moving in. To calculate velocity, you divide your distance traveled by the time it took to travel that distance and you add your direction to it.
So to conclude, 300/100= 3 m/s South
To find the mass in grams of Selenium, you use the moles you have and multiply it by the molar mass.
5489 Moles Se * (79g Se / 1mole Se) =433631g of Se
Answer:
a is write
Explanation:
Why are all ionic compounds crystalline in structure?
Ionic compounds are generally hard, but brittle. ... The repulsive forces between like-charged ions cause the crystal to shatter. When an ionic crystal breaks, it tends to do so along smooth planes because of the regular arrangement of the ions.
