Challenge: A chemical equation is balanced when each side of the equation includes the same number of each type of atom.
nirvana33 [79]
If the reactants are the same the equations are balance but if the reactants are not the same you have to make them balance, however if the reactants are not balance  in order to balance the equation you need to use coefficient to balance the reactants and products of particular chemical reaction.
yet for Photosynthesis the equation 
CO_2 + H_2O => C_6H_12O_6 + H_2O + O_2
Find the ugliest Compound in equation and do not balance first the repetitive Element.
A)So the ugliest one is C_6H_12O_6 and the C is not repetitive and have six atoms so there fore we multiply 6 as coefficient with carbon dioxide.
6CO₂+ H₂O → C₆H₁₂O₆+H₂O+O₂ but oxygen will get 12 atoms because is to all Carbon dioxide.
B) Then we have carbon balanced then we are going to balance Hydrogen, yet on product side it have 14 but on the reactant side it have 2 but Oxygen on product side is 9 there but on reactant side we have 1 so there fore we have to multiply water on reactant side by 12 and on product side multiply water with six and in addition multiply oxygen with 6 which land you at:
6CO₂+ 12H₂O → C₆H₁₂O₆+6H₂O+6O₂.
so we will have 24 hydrogen and 24 oxygen on both sides. 
Hope that helps you.

satela [25.4K]
The nurse must assess the patient's pain intensity before and after administering an opioid analgesic. The respiratory rate and level of consciousness need to be assessed because respiratory depression and sedation are two adverse effects of opioid analgesics. Seizure activity, electrolytes, liver function, blood glucose level, and mental status may need to be assessed during opioid analgesic therapy <span>related to adverse effects.

<h2>Carrot in 0.2M salt solution</h2>

Explanation:

  • Carrot cuts put in 0.2M salt answer for a few hours gets flabby (limp).
  • Carrot cuts set in freshwater for a few hours gets <em>turgid  (firm).</em> From this, we can conclude that such as.  
  1. Freshwater is hypertonic and the salt arrangement is hypotonic to the cells of the carrot cuts.
  2. <em>Freshwater and salt arrangement are both hypotonic</em> to the cells of the carrot cuts.  
  3. Freshwater is isotonic and the salt arrangement is hypertonic to the cells of the carrot cuts.  
  4. <em>Freshwater is hypotonic</em> and the salt arrangement is hypertonic to the cells of the carrot cuts.  
  5. Freshwater and the salt arrangement are <em>both hypertonic to the cells of the carrot cuts.</em>

Descirbe the structure of bone
vodomira [7]
The basic structure of bones is bone matrix, which makes up the underlying rigid framework of bones, composed of both compact bone and spongy bone. The bone matrix consists of tough protein fibers, mainly collagen, that become hard and rigid due to mineralization with calcium crystals.

Shalnov [3]

Answer:

True

Explanation:

Spinal nerve divides into several branches after passing through its intervertebral foramen. These branches are called rami. A spinal nerve gives off several branches such as anterior ramus, posterior ramus, rami communicantes, and a meningeal branch. The meningeal branch reenters the vertebral cavity through the intervertebral foramen. It serves to supply the vertebrae, vertebral ligaments as well as the blood vessels of the spinal cord, and meninges.
