Water dude lol H²0 (dont you know?) #rhymes
H²o → Hydrogen [The 2 means there are two hydrogen atoms], Oxygen = H²O
Angle of Solar Radiation and Temperature
I’m not 100% sure, but I think hydrogen gas is also produced :)
A. Phase changing. When phase changes nothing chemically changes about the substance, its still the same thing.
Using the law of dilution :
Mi x Vi = Mf x Vf
2.00 x Vi = 0.15 x 100.0
2.00 x Vi = 15
Vi = 15 / 2.00
Vi = 7.5 mL
hope this helps!
