Answer:
Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water. ... For example, both processes synthesize and use ATP, the energy currency.
Answer:
The correct answer is A. An ionic compound
Explanation:
Sodium (metal) and chlorine (nonmetal) form an ionic bond to each other, forming the NaCl (sodium chloride) molecule. Sodium transfers an electron to chlorine, which is missing an electron to complete the octet rule.
(c)Low Temperature of the Reactants can decrease the rate of a chemical reaction.
How temperature effects the rate of a chemical reaction
Chemical reactions typically occur faster at higher temperatures. Food can spoil quickly when left on the kitchen counter. However, the lower temperature inside of a refrigerator slows that process so that the same food remains fresh for days. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.Thus decrease in the temperature of a reaction can help in decreasing the rate of a chemical reaction.Lower the temperature lower the chemical reaction rate.
