Here the given statement 'A chemist mixes sodium with water and witnesses a violent reaction between the metal and water,' can be classified as an observation as it explains what the chemists observes as a result of his chemical experiment or test..
Increase in temperature makes the atoms speed up, and decrease in temperature makes the atoms move slower.
Answer:
ΔE = 5.02 x 10⁻¹⁹ j
Explanation:
ΔE (photon) = h·f = (6.63 x 10⁻³⁴ j·s)(7.57 x 10¹⁴ s⁻¹) = 5.02 x 10⁻¹⁹ j
h = Planck's Constant = 6.63 x 10⁻³⁴ j·s
f = frequency (given) = 7.57 x 10¹⁴ s⁻¹
I think the correct answer from the choices listed above is option C. Cooking oil is not an example of a heterogeneous mixture. This type of mixture is a system where the properties are not uniform all through out the system and examples are <span>trail mix, oil and vinegar dressing and chocolate chip cookies.</span>
