Will get 1. balance the equation for the reaction between zinc and hydrochloric acid. zn + hcl zncl2 + h2 2. balance the equation for the reaction between iron (steel wool) and oxygen (water). fe + o2 fe2o3

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.

Many ionic compounds and a few highly polar covalent compounds are because they completely ionize in water to create a solution filled with charged ions that can conduct an electric current.
