Answer:
Q = 1.68 Kcal
Explanation:
∴ m H2O = 12.0 g
∴ T1 = 35°C ≅ 308 K
∴ T2 = 175°C ≅ 448 K
∴ ΔT = T2 - T1 = 175 - 35 = 140 °C
∴ Cp H2O = 1 cal /g.°C
⇒ Q = (12.0 g)(1 cal/g°C)(140 °C)
⇒ Q = (1680 cal)*(Kcal/1000 cal)
⇒ Q = 1.68 Kcal
Answer:
1.Gamma Rays
2. Infrared
3. Radio Waves
Explanation:
Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Materials: laser pointer/ flashlight with a paper with a small slit, glass prism
step 1.) turn on the laser pointer point it up to the ceiling.
step 2.) point to prism, explain how the light refracts in the prism. and how it changes.

Answer:
2 x 12.0g/mol + 1 x6 + 16.0 g/mol
Explanation:
molecular formula = C₂H₆O ( carbon= 12g/mol H= 1g O=16)
= 2 x 12 + 6 x 1 + 16
= 46 g Molecular mass
