Answer:
–0.13 Pa.m²
Explanation:
From the question given above, the following data were obtained:
Measurement (Pa.mm²) = –1.3×10⁵ Pa.mm²
Measurement (Pa.m²) =?
We can convert from Pa.mm² to Pa.m² by doing the following:
1 Pa.mm² = 1×10¯⁶ Pa.m²
Therefore,
–1.3×10⁵ Pa.mm² = –1.3×10⁵ Pa.mm² × 1×10¯⁶ Pa.m² / 1 Pa.mm²
–1.3×10⁵ Pa.mm² = –0.13 Pa.m²
Thus, –1.3×10⁵ Pa.mm² is equivalent to –0.13 Pa.m².
To find the number of atoms in the sample of copper, we need its atomic mass and the use of the Avogadro's number to find the equivalent units in terms of atoms.
68.7 g Cu ( 1 mol / 63.55 g ) ( 6.022 x 10^23 atoms / 1 mol ) = 6.51 x 10^23 atoms Cu
Answer:
Nitrification is a biological process by which ammonia is oxidized to nitrites (
) and then to nitrates (
) by action of specialized bacteria in nature (such as <em>nitrosomonas</em> and <em>nitrobacter</em>).
Explanation:
This two-step process utilizes molecular atmospheric oxygen and ammonia and ammonium components of soil and nature.
<em>(a.) Ammonia and ammonium compounds to nitrite</em>
→ 
→ 
<em>(b.) Nitrite to nitrate</em>
→ 
<em>(c.) The reverse process involves reduction of nitrates to molecular nitrogen, called denitrification (with succinic acid in the equation below).</em>
→
(
and
is an intermediate product in this process.)
