Halogens I believe because it included fluorine which is the most reactive nonmetal
Answer:
a) 6.02 × 10^23
b)6.02×10^23
c)3.01×10^24
d) 3.612×10^24
In every mole of a substance there are 6.02×10^23 entities.
in ( c) there are 5 carbon atoms . 5 is multiplied by the number of moles of the molecule and then multiplied by 6.02×10^23. ( using the formula N=nL )
Answer:
M₂ = 0.23 M
Explanation:
Given data:
Volume of HNO₃ = 22.5 mL
Volume of NaOH = 31.27 mL
Molarity of NaOH = 0.167 M
Molarity of HNO₃ = ?
Solution:
M₁ = Molarity of NaOH
V₁ = Volume of NaOH
M₂ = Molarity of HNO₃
V₂ = Volume of HNO₃
M₁V₁ = M₂V₂
0.167 M × 31.27 mL = M₂ × 22.5 mL
5.2 M. mL = M₂ × 22.5 mL
M₂ = 5.2 M. mL /22.5 mL
M₂ = 0.23 M
The six metalloids are boron, silicon, germanium, arsenic, antimony, and tellerium.
