Answer:
The correct answer is B. Dull appearance
Explanation:
Your answer is B and the element is Carbon
So what your looking for is matching isotopes. Isotopes are elements that are the same in amount of protons but different in mass meaning different number in neutrons. Because when you add the total protons and neutrons together you get your atomic mass. So this can be written as X=said element, top number above=different atomic mass, bottom number below=atomic number. Hope this help!!
Be careful because answer A has same masses but different atomic numbers so different atoms(elements)!!!
MITOCHONDRIA.
The powerhouse of a cell is Mitochondria, don’t you even forget this.
Well the molar mass of CO2 would be that 1 mol of CO2 would have the mass of 44.0 grams. So 11 mol of CO2 would have 11 • 44 or 484 grams.
The answer would be C. hope this helped.
