What is the pH of a solution prepared by dissolving 4.09 g of KOH in water to make 706 mL of solution? Round your answer to three decimal places.

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)

Predict the products butane (c4h10) + oxygen —>
