Answer:
2.954 g
Explanation:
One banana contains 422 mg
One banana weighs 118 g
To make our calculations easier, we will convert both unit to the same power, that is both of them will be in g.
422 mg = 422/1000 = 0.422 g
If one banana contains 0.422 g of potassium, then 7 bananas(since he eats 1 per day) will weigh
0.422 * 7 = 2.954 g
Thus, after a week, he would have ingested at least 2.954 g of potassium.
I hope you understand the explanations. Thanks
Answer:
electrons can bond atoms together
Explanation:
when two atoms share electrons,they are locked together by that sharing.These are called covalent bonds...but when an atom gives one of its electrons to another atom ,they are held together by electric forces.HOPE THAT HELPED☺
In a) the final equation is AgNO3 + KCl = AgCl + KNO3, b) Ni(NO3)2 + Na2S = 2NaNO3 + NiS; c) CaCl2 + Na2CO3 = 2 NaCl + CaCO3. In 2) The total net equation is Ca 2+ + CO32- = CaCO3 (s).
They're based on the results of your testing.
An atom is the smallest unit of matter that has the properties of an element. It is composed of a dense core called the nucleus and a series of outer shells occupied by orbiting electrons. The nucleus, composed of protons and neutrons, is at the center of an atom.
