all charged objects create an electric field around them. what two factors determine the strength of two electric fields upon the charged objects creating them?
1) how charged the object creating the field is and the density of the charged objects
2) how charged the object creating the field is and weather the objects are positively or negatively charged
3) how charged the object creating the field is and the mass of the two charged objects
4) how charged the object creating the field is and the distance between the two charged objects

You exhale co2 which is produced during cellular respiration. co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid. the more physical activity you engage in, the more co2 your body is producing. you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw. can you see a change in the color of the indicator?

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
