Answer:

pOH = 9.

Explanation:

The inverse relationship between the pH and pOH of any given solution can be written as:

pH = 14 - pOH

Or conversely:

pOH = 14 - pH

With the above information in mind we can <u>use the given pH to calculate the pOH</u>:

pOH = 14 - pH

pOH = 14 - 5

pOH = 9

Thus, black coffee has a pOH of 9.

What is the molecular formula of compound x?
givi [52]
Since there is one carbon with 4 Fluorines attached to it, and both compounds are no metals, we use the covalent method for naming,

Here we ignore the prefix for the first element if it is 1. Mono. Then pay attention to the second one, it would be tetra, because tetra means 4. Here there are 4 fluorines.

Drop ine and place ide

CF4 = carbon tetrafluoride.

Given the reaction: cu(s) + 4hno3(aq) → cu(no3)2(aq) + 2no3(g) + 2h2o(l )as the reaction occurs, what happens to copper?
katrin [286]
From the reaction between Cu and HNO₃, the formed gas is NO₂ instead of NO₃. Hence the correct balanced equation would be,
Cu(s) + 4HNO₃(aq) → Cu(NO₃)₂(aq) + 2NO₂(g) + 2H₂O<span>(l)

Here, Cu goes to </span>Cu(NO₃)₂ by changing its oxidation number from 0 to +2 while NO₃⁻ goes to NO₂ by reducing its oxidation state from +5 to +4 . Hence Cu is oxidized by HNO₃ in the reaction.
