Answer:
The molecules in a gas have more freedom of movement than molecules in a liquid. Molecules in gas are free to move away from each other, so gas can expand to fill its container.
Explanation:
Answer:
- Third choice:<em> energy present in the glucose and oxygen that is not needed for the formation of carbon dioxide and water is released to form energy/ATP.</em>
Explanation:
<u>1) Chemical equation (given):</u>
- C₆H₁₂O₆ + 6 O₂ --> 6 CO₂ + 6 H₂O + energy
<u>2) Chemical potential energy:</u>
Each compound stores chemical potential energy. This energy is stored in the chemical bonds.
Due to every substance has its own unique chemical potential energy, when a chemical reaction takes plase, yielding to the change of some substances, some energy is absorbed (when bonds are formed) and some energy is released (when bonds are broken).
<u>3) Conservation of energy:</u>
Then, if the sum of the bond energies of the final products is less than the sum of the bond energies of the reactants, the<em> law of conservation of energy</em> rules that the difference between the total energies of the products and reactants must be released to the surroundings.
That is what is happening in the given reaction:
- C₆H₁₂O₆ + 6 O₂ --> 6 CO₂ + 6 H₂O + energy
The term energy in the product side means that energy is conserved because it is being released due to the the glucose and oxygen (reactant side) have more energy stored in their bonds than the energy needed for the formation of carbon dioxide and water, so that excess of energy is released to form energy/ATP.
<u>Summarizing:</u>
- The energy on the product side added to the energy of carbon dioxide and water equals the energy of the glucose and oxygen and the final balance is:
- ∑ Energy of the reactants = ∑energy of the products + released energy, supporting the law of conservation of energy.
The correct answer is - D. Savannah is more humid and has higher precipitation than San Diego.
Despite both Savannah and San Diego being on the coast of an ocean, they do have differences in the climate. Savannah comes out on the Atlantic coast, while San Diego comes out on the Pacific Coast. Savannah is influenced by warm and wet air masses all year round, while San Diego is predominantly influenced by dry air masses because of the colder ocean currents. Savannah has a relatively stable temperature throughout the year, and it also has solid amount of precipitation, with the humidity in the air being always high. San Diego, on the other side, is hot for most of the year during the days, but the nights are relatively cool. There's very little precipitation, and the humidity in the air is not as high as in Savannah.
Answer:
So oxidation reactions need not involve oxygen. This redox reaction is actually the sum of two separate half-reactions (a reduction half-reaction and an oxidation half-reaction).
The answer is B, because the zinc is dissolved in the copper. The solute is always dissolved in the solvent.
