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.
Answer:
the mineral formed when a hot water solution cooled
Answer:
element
Explanation:
we know that helium is a pure substance although helium atoms are sometimes mixed with their isotopes it is still the same element. since there is no other element combined with helium this makes it an element.
<h2>Answer:</h2>
Given data:
Volume of solution: 500 ml
Mass of 10 ml solution: 10.7 g
Density of whole solution: ?
<h3>Solution:</h3>
Mass of 500 ml solution : 10.7/10 * 500 = 535 g
Density = Mass/ volume
<u>Putting values in formula :</u>
D = 535/500 = 1.07 g/ml
Hence Density = 1.07 g/ml
8.4 grams. I think but I’m not 100% sure
