Ans 1. Both

Ans 2. Once inside plants, carbon moves through food chains, where organisms become nutrients including herbivores, carnivores and ultimately, decomposers. Once buried in the soil, carbon can be converted into fossil fuels over long periods of time and then also reenter the atmosphere by combustion. The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law

Ans 3. Most of the chemical energy needed for life is stored in organic compounds as bonds between carbon atoms and other atoms. The law of conservation of energy states that energy can not be created or destroyed. Thus, just like matter energy is also conserved in the process.

Hope it helps

Predict the energy trend as a substance changes from a solid to liquid to gas on this graph.

Vladimir [108]

Answer:
Option-A (<span> It would increase from bottom left to top right) is the correct answer.

Explanation:
As we know converting solids into liquids and converting liquids into gases require energy. This energy provided increases the energy of the state and its particles start moving with higher velocities. Therefore, the energy of solids will be lower than liquids and gases respectively. While, liquids have greater energy than solids but less energy than gases. And, gases are the most energetic than solids and liquids.</span>

How is the information about cats found in myths and fairy tales and legends different from information gathered through science

forsale [732]

Scirnce uses a method of testing to declare rules or facts. myth and fairy tales have no way of being tested. cats are a physical creature we can see, test, and observe. a mythical idea canny be tested. for example: mermaids cannot be tested as we have none to observe.

Match the correct definition with the correct term from questions 10-13: A. Internal energy B. Latent heat C. Chemical (bond) en

Marizza181 [45]

Answer: A. Internal energy : May be viewed as the sum of the kinetic and potential energies of the molecules

B. Latent heat: The internal energy associated with the phase of a system.

C. Chemical (bond) energy : The internal energy associated with the atomic bonds in a molecule

D. Nuclear energy : The internal energy associated with the bonds within the nucleus of the atom itself

Explanation:

Internal energy is defined as the total energy of a closed system. Internal energy is the sum of potential energy of the system and the kinetic energy of the system. It is represented by symbol U.

Latent heat is the thermal energy released or absorbed by a thermodynamic system when the temperature of the system does not change. It is thus also called as hidden heat.

Chemical energy is the energy stored in the bonds of molecules.

Nuclear energy is the energy which is stored in the nucleus of an atom called as binding energy within protons and neutrons.

) In another experiment, the student titrated 50.0mL of 0.100MHC2H3O2 with 0.100MNaOH(aq) . Calculate the pH of the solution at

andrew11 [14]

Answer:

Explanation:

moles of acetic acid = 500 x 10⁻³ x .1 M

= 5 X 10⁻³ M

.005 M

Moles of NaOH = .1 M

Moles of sodium acetate formed = .005 M

Moles of NaOH left = .095 M

pOH = 4.8 + log .005 / .095

= 4.8 -1.27875

= 3.52125

pH = 14 - 3.52125

= 10.48
