Call what you have to find is x
nHCl/V=12M
nHCl=2.0,25=0,5
->x=0,5.12=6 (600 ml)
Answer:
11.4 moles
Explanation:
Your chemical equation for the reaction of zinc and nitric acid will be
Zn + 4 HNO₃ --> Zn(NO₃)₂ + 2 NO₂ + 2 H₂O
To solve the problem, you need to use stoichiometry. For every 1 mole of zinc, you will need 4 moles of nitric acid. Divide 45.60 by 4. Your answer should be 11.4 moles.
D) Silicon is an example of a metalloid.
It has some of the properties of metals and some of the properties of nonmetals.
In the Periodic Table, metalloids sit on either side of a zig-zag line separating metals from nonmetals.
In the diagram below, Fe and Au are metals, while He is a nonmetal.
Answer:
The correct answer is option (1).
Explanation:
Mass of the sample = 5.5 g
Percentage of carbon in sample = 35 %
Percentage of oxygen in sample = 100% - 35%

Mass of carbon in a sample: (35%) of 5.5 g

Mass of oxygen in a sample: (100%-35%) of 5.5 g
