Unit' is the word used to describe how something is measured. When researching a question in science, we collect data, interpret it, and share the results with other scientists. A common measurement system allows us to make direct comparisons instead of having to know things like how much a certain animal weighs.
<span>choices are:
Zirconium metal plus hydrogen chloride yields zirconium chloride solution and hydrogen gas
Xenon solid plus hydrochloric acid yields xenon chloride and hydrogen gas
Zinc metal plus hydrogen chloride yields zinc dichloride plus hydrogen gas
Zinc metal plus an aqueous solution of hydrochloric acid yields an aqueous solution of zinc chloride plus hydrogen gas
right ans is:

A) Exosphere
This is the outermost layer of the atmosphere
PH and pOH are opposites, so pH can be determined by subtracting pOH from 14
pH = 14 - 7.9 = 6.1
