Answer:Sunlight

Explanation:

Sunlight is a physical factor that really determine the amount of plant life available in an ecosystem. Plants depend on sunlight to produce their own food via photosynthesis. Hence in the absence of sunlight, the amount of plant life will drastically reduce in a given ecosystem. Sunlight is indispensable for plant growth.

Answer:

3.59x10^21 molecules

Explanation:

1mole of a substance contains 6.02x10^23 molecules.

Therefore, 1mole of C8H18 will also contain 6.02x10^23 molecules

1mole of C8H18 = (12x8) +(18x1) = 96 + 18 = 114g.

1mole (i.e 114g) oh C8H18 contains 6.02x10^23 molecules.

Therefore, 0.68g of C8H18 will contain = (0.68 x 6.02x10^23)/114 = 3.59x10^21 molecules

Why is it important to collect all data during experiments, rather than make inferences of what will happen?
Paraphin [41]

Answer:

It is important to collect all data first, or else your guesses could purely be the opposite of the right answer. If you make inferences of what might happen, your guesses may be purely fictional, and totally off-topic. During experiments, this step is important.

Calculate the energy of one photon of yellow light that has a wavelength of 5.89x10^-7m.​
Viktor [21]

Answer:

E = energy = ? ,

λ = Wavelength = 5.89 × 10^-7 m —> = 589 ×10 ^-9 m ,

h =Planck constant = 6.63 × 10^-34 J.s ,

f = frequency of photo/ electromagnetic radiation = c/λ ,

c = Speed of light in a vacuum = 3 × 10^8 m/s

___o___o____

E = hf \\  \\ E = h \frac{c}{λ}  \\  \\  E = 6.63 \times  {10}^{ - 34}  \frac{3 \times  {10}^{8} }{5.89 \times  {10}^{ - 7} }  \\  \\E =  \frac{6.63 \times  {10}^{ - 34} \times 3 \times  {10}^{8}  }{5.89 \times  {10}^{ - 7} }   \\  \\ E =  \frac{663 \times  {10}^{ - 36} \times 3 \times  {10}^{8}  }{589 \times  {10}^{ - 9} }  \\  \\ E =  \frac{1989 \times  {10}^{ - 28} }{589 \times  {10}^{ - 9} }  \\  \\ E = 3.37691 \times  {10}^{ - 19} J
