What is the mole fraction of CoHo for a solution of 75.6 g CoHo in 480.6 g CCl4?
Round your answer to 3 decimal spaces, even if sig figs are not
conserved.

beta decay is the answer

b. examine and describe cells

elements make up everything, and they combine to make compounds.

the answer is c

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
