Kendra conducts an experiment. she mixes two chemicals, resulting in a chemical reaction. based on kendra’s experiment, what can be concluded about the original matter before mixing? it did not change in identity but did change properties. it changed in identity but not properties. it changed in identity and properties. it did not change in identity nor properties.

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.

Melting increases as mass increases. since alkanes are not branched molecular structures, the one with the heavier mass will have higher melting point.  octane's mp > butane's mp

The lewis structure for co2 has a total of  16  valence electrons.  hoped i can i get brainliest
