La presa de las Tres Gargantas en China produce 20 000 MW. Teniendo en cuenta que la potencia media contratada por familia es de 5 kW¿Cuántos 2 podrán ser abastecidos con energía?

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1

When using the scientist method, which step comes last?
