Photosynthesis
Explanation:
Plants use the energy they get from the sun, take in water from the roots, and take in carbon dioxide from the air to make glucose. AKA their food.
Answer:
672.6 grams
Explanation:
molar mass of 1 mol of C₈H₁₈ = 114 grams
so mass of 5.9mol of C₈H₁₈ = 114* 5.9= 672.6 grams
Answer:
The correct option is: C. tetrahedral, polar
Explanation:
Trifluoromethane, also known as Fluoroform, is a chemical compound with the molecular formula CHF₃.
Since three fluorine atoms and one hydrogen atom is bonded to the central carbon atom and there are zero lone pairs on the carbon atom. Therefore, the<em> molecular geometry and shape of CHF₃ is tetrahedral</em>.
As there are three carbon-fluorine polar bonds in CHF₃ molecule, thus there is a net dipole moment. <em>Therefore, CHF₃ is a polar molecule.</em>
