Answer:
The correct answer is - both act only between non-atomic particles.
Explanation:
The decreasing order of their relative strength is - the strong force, electromagnetism, weak force, gravity.
so, A would be here = gravity
B would be = weak force
C would be = strong force
The weak and strong forces both are fundamental forces that act on sub-atomic particles only such as quarks.
The balanced equation is
2Al + 2KOH + 6H2O -----> 2K[Al(OH)4 + 3H2.
From the above we see that 2 moles of K react with 2 moles of Al.
So 2 .94 moles of aluminium will react with 2.94 moles of potassium (answer)
4.8 g/cm3 with sig figs since it's mass/volume you divide 76 grams by 16 cm3
D.) the original components retain their individual properties
