They didn’t give you a word bank? It’s fine if they didn’t ill answer it either ways I’m just asking first
The term simple diffusion<span> refers to a process whereby a substance passes through a membrane without the aid of an intermediary such as a integral membrane protein. The force that drives the substance from </span>one<span> side of the membrane to the other is a concentration gradient. Hope this helps.</span>
Thank you for posting your question here at brainly. Below is the solution for the above problem. I hope it helps.
period of orbit at 26000 AU
<span>P = a^(3/2) </span>
<span>= (26000)^(3/2) = 4,192,374 years (Earth)</span>
The correct answer is d. 8p+; 9n; 10e−
Oxygen exists in three isotopes ¹⁶O, ¹⁷O and ¹⁸O. The atomic number of oxygen is 8. It means its nuclei has 8 protons. The given is oxide⁻² anion. This means it has gained 2 electrons. Thus, oxide anion have 8 protons and 10 (8+2) electrons. The number of neutrons depends on the isotope, in this question mass number is given¹⁷O. The mass number is the sum of the protons and neutrons in the nucleus. Hence, number of neutrons oxide anion will be 17-8 = 9 neutrons.
