Answer:
0.004522 moles of hydrogen peroxide molecules are present.
Explanation:
Mass by mass percentage of hydrogen peroxide solution = w/w% = 3%
Mass of the solution , m= 5.125 g
Mass of the hydrogen peroxide = x
Mass of hydregn pervade in the solution = 0.15375 g
Moles of hydregn pervade in the solution :
0.004522 moles of hydrogen peroxide molecules are present.
A or C are the best options
7 count the dots in the middle for you answer and if not it’s 3
Answer: Igneous rocks may be simply classified according to their chemical/mineral composition as felsic, intermediate, mafic, and ultramafic, and by texture or grain size: intrusive rocks are course grained (all crystals are visible to the naked eye) while extrusive rocks may be fine-grained (microscopic crystals) or glass.
