Answer:
"...for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny."
(A)
<span>You
are right in that bananas contain potassium and K-40 is a naturally
occurring potassium isotope AND the K-40 in an average banana does decay
at a rate of about 31 ATOMS per second (half-life is > 1 billion
years). This is an extremely low level of radiation and nothing to worry
about. Bananas will definitely NOT cause a "nuclear winter."</span>
Answer:
Both
Explanation:
Baking soda is the common name of sodium bicarbonate or sodium hydrogen carbonate. Both the empirical and molecular formula of sodium bicaronate is NaHCO3 .
Baking soda is soluble in water and has a molar mass of almost Molar mass: 84.007 g/mol.
If we look at molecular formula of NaHCO3, it has molar ratio of 1:1:1:3 and we can say that every thing in this molar ratio make whole mass as : 23g +1 g +12 g+48 g= 84 grams.
Since we know that empirical formula demonstrates the simplest ratio of elements present in a compound and molecular formula demonstrates the total molar ratio of each element in a compound, hence we see that its empirical and molecular formulas both are already simple because they have simplest ratio which cannot be simplified further.
Hope it help!
