Answer:
convection could be a pot on a stove, radiation could be the sun and heat waves, and conduction could be a cup with coffee.
Explanation:
Conduction occurs when two objects are in direct contact with each other.
Convection is the transfer of heat through liquids and gases. Convection occurs above a hot surface because hot air expands and rises and is replaced by cooler, denser air.
Radiate energy is given off by a hot object and directly absorbed by another cooler object. This cause the cooler object to get warmer. Radiation can occur even if no air is present.
Bromine is in gaseous state
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

Answer:
The bones of the skull and spinal column
Explanation:
The central nervous system is better protected than any other system or organ in the body. Its main line of defense is the bones of the skull and spinal column, which create a hard physical barrier to injury.
