Well...........thanks for posting anyway.
Answer:
Three pairs of walking legs, wings, body divided into three segments, pair of sensory antennae.
Explanation:
Answer:
(a). Biological fixation
(b). Fixation by lightning
Explanation:
Gaseous nitrogen in the atmosphere has to be converted or "fixed" into a suitable form before it can be utilised by living organisms.
There two main ways of nitrogen fixation are
(a). Biological fixation: Majority (approximately 90%) of nitrogen fixation is carried out by bacteria. Bacterias such as Cyanobacteria transforms nitrogen into ammonium and ammonia : N2 + 3 H2 → 2 NH3. The produced ammonia can then be taken in directly by plants and /or the conversion products of ammonium and ammonia may further react in the process of nitrification.
(b). Fixation by lightning: Lightning energy causes the combination nitrogen (N2) and water (H2O) forming nitrates (NO3) and ammonia (NH3) . Rain water dissolves the formed nitrates and ammonia and the solution is drained into the ground, where they can be reached by plants plant roots for consumption.
The total pressure is given by
A system a STP will have a total pressure of 101.325KPa, and so we make P_C the subject of the formula and solve
No It is not correct.
Correct oxidation number of hydrogen in NaH,H2 and H2S are:
- Let x be the Oxidation state of ’H’ by oxidation state rule.
x+1 =0 (Sodium has +1 Oxidation state )
x=−1
Therefore, -1 is oxidation number of Hydrogen in NaH.
- The oxidation number of an element's atom in its standard state is zero. As a result, the oxidation number for H2 is zero.
- The hydrogen oxidation number in H2 is +1. As a result, that hydrogen atom can be reduced to lower oxidation states of hydrogen, such as 0 and -1. However, because +1 is the highest oxidation state of hydrogen, the hydrogen atom cannot be reduced any further.
<h3>What is oxidation number?</h3>
In simple terms, the oxidation number is the number assigned to elements in a chemical combination. The oxidation number is the number of electrons that atoms in a molecule can share, lose, or gain when forming chemical bonds with atoms of a different element.
