These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
Answer:
The light goes through
Explanation:
The light goes through the transparent glass without being reflected or absorbed, for example, a window is a transparent glass, you never see light being reflected off of a window

The Correct option is E. Chemical energy to Mechanical energy.
Answer:
Volume of HBr = V₂ = 7.5 mL
Explanation:
Given data:
Volume of NaOH =V₁= 25.0 mL
Molarity of NaOH =M₁= 0.150 M
Molarity of HBr =M₂= 0.5 M
Volume of HBr =V₂= ?
Solution:
M₁V₁ = M₂V₂
0.150 M ×25.0 mL = 0.5 M×V₂
V₂ = 0.150 M ×25.0 mL / 0.5 M
V₂ = 3.75 M.mL /0.5 M
V₂ = 7.5 mL
