Consider this combination reaction:
2mg(s)+o2(g)→2mgo(s) δh=−1204 kj
what is the enthalpy for the decomposition of 1 mole of mgo(s) into mg(s) and o2(g)?

Which element would mostly likely have an electron affinity measuring closest to zero

Precision can be defined as the o exact center of a data set. o reproducibility of a measured value. o correlation between two variables that are measured in a data set agreement between a measured value and an accepted value.

Which of these features are formed when hot groundwater is forced out through cracks in the earth's surface?
