the pH of soil X is 7.5 while that of soils Y is 4.5 which of the two coils should be treated with powered talked to adjust its PH

Design techniques and materials that reduce the negative environmental impact of a structure are referred to as

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]

What is the value of the standard enthalpy of formation of an element in its most stable form?
