Explanation:
Answer:Water contains almost one thousand times more matter than the same volume of air would, therefore it is denser. ... If 500 mL of a liquid has a density of 1.11 g/mL, what is its mass? ... Density is the mass per unit of volume of a substance. ... A block of platinum with a mass of 4,290 kilograms has a volume of .2 cubic meters.
Explanation:
<span>ANSWER:
Organic reactions proceed at a very SLOWER rate.
Reasoning:
</span><span>Organic reactions are chemical reactions involving organic compounds. They are less soluble</span> in water than inorganic compounds. Therefore, organic compounds react at a slower rate and produce a much more complex set of products than inorganic compounds.
Given:
E = 7.3 × 10–17 Hz
h= 6.63 × 10–34 J•s
Now <em>E = hf</em>
where E is the energy of the photon
h is the Planck's constant
f is the frequency of the photon
Substituting the values in the equation we get
E= 7.3 × 10^-17 × 6.63 × 10^-34
<u>E= 4.8399 × 10^-50 J. </u>
