in reaction a, each sodium atom gives one electron to a chlorine atom. in reaction b, an isotope of oxygen decays to form an iso
tope of nitrogen. which statement best describes the energy that is released per gram by these reactions? a.reaction a releases more energy than reaction b releases. b.reaction b releases more energy than reaction a releases. c.reaction a and reaction b release equal amounts of energy. d.neither reaction a nor reaction b releases energy.
The answer is <span>b.reaction b releases more energy than reaction a releases.
The reaction a is an example of a chemical reaction while the reaction b is an example of a nuclear reaction. </span><span>Some main differences between the chemical and nuclear reactions are: - The nuclear reaction releases more energy per gram. - The nuclear reaction takes place in the nucleus of the atom, while in chemical reactions include electrons. - In the nuclear reaction, part of the mass is converted into energy, which </span><span>violates the law of conservation of mass. </span> Therefore, the nuclear reaction (reaction b) will release more energy than the chemical reaction (reaction a).
Do you think there is a quantitative relationship between transpiration rate and number or size of leaves on the stem? Explain your answer. Yes, the more leaves a plant has, means more stomata will be available for transpiration. ... Without light to facilitate photosynthesis, most plants close their stomata at night.
Plants make up most of our oxygen here on earth, because of the carbon cycle and photosynthesis. They take carbon dioxide, and turn it into oxygen. And not only that, but some animals live in trees to protect themselves from birds and other animals.
