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.
Oil molecules like to stick to other oil molecules more than they like to stick to water molecules. This is because mineral oil has nonpolar molecules and water has polar ones.
<h2>Answer:</h2>
<u>Yes the statement is</u><u> True</u>
<h2>Explanation:</h2>
THC is a chemical which stands for delta-9-tetrahydrocannibinol or Δ-9-tetrahydrocannabinol (Δ-9-THC). This chemical is a cannabinoid molecule in marijuana or cannabis that has long been known as the main psychoactive ingredient in marijuana which means that it is the substance that causes users to experience the marijuana high. It can be detected in the blood up to 20 hours after ingestion, and it's stored in the body fat and organs for three to four weeks after ingestion.
Answer: 2.48×10^-17 J
Explanation:
Given the following :
Wavelength = 8nm (8 x 10^-9 m)
Energy(e) of X-ray =?
Energy=[speed of light(c) × planck's constant (h)] ÷ wavelength
Speed of light = 3×10^8m/s
Planck's constant = 6.626×10^-34 Js
Wavelength = 8 x 10^-9 m
Energy = [(3×10^8) * (6.626×10^-34)] / 8 x 10^-9
Energy = [19.878×10^(8-34)] / 8 x 10^-9
Energy = 2.48475 × 10^(-26+9)
Energy = 2.48×10^-17 J
The reaction is an unbalanced redox reaction hence, the reaction can be balanced by using the half-reaction method.
<h3>What is a redox reaction?</h3>
The term redox reaction refers to the reactionnin which electrons are transferred hence one specie is oxidized while the other specie is reduced.
Looking at the reation as shown, we can see that the reaction is an unbalanced redox reaction hence, the reaction can be balanced by using the half-reaction method.
