Answer:

See below.

Explanation:

The period is not the same regardless of the string length.

The longer the length the  greater is the period (  the period varies directly with the square root of the length).

The equation of the relationship  is  T = 2π√(l/g)  where l = the length of the string and g is the acceleration due to gravity.

According to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in which order?
saveliy_v [14]

According to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in alphabetical without taking prefixes into name.

A hydrocarbon would be an organic molecule in organic chemistry that is made completely of hydrogen as well as carbon. A good example of group 14 hydrides includes hydrocarbons. In general, hydrocarbons lack color and are hydrophobic. Typically, their faint smells are compared to that of gasoline and lighter fluid.

  • The longest unbroken carbon chain should be found and named.
  • Name the groups that make up this chain but instead identify them.
  • Beginning at the end of the chain closest to a substituent group, fraction the chain sequentially.
  • Give each substituent group a corresponding number but also name to indicate its placement.

Therefore, according to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in alphabetical without taking prefixes into name.

If a plant produces 9.31 mol of C6H12O6, how many moles of H2O are needed?
Mashutka [201]

The complete balanced chemical equation for photosynthesis in plants is:

6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂

Based on the balanced equation the molar ratio between H₂O and C₆H₁₂O₆ is 6:1

This means that 6 moles of H₂O is need for every 1 mole of C₆H₁₂O₆

9.31 mol of C₆H₁₂O₆ x (6 moles of H₂O / 1 mole of C₆H₁₂O₆) = 55.86 moles of H₂O

Thus the moles of H₂O need is 55.86 .
