The answer is Hydrogen
This is what happens when acids react with metals
Answer:
The number of pioneer species get less as the area has more soil to support complex plants and the competition decreases the role of pioneer species.
Explanation:
Pioneer species like Lichens and Mosses inhabit an area after a major disturbance, such as a volcanic eruption. However, with time the number of pioneer species decreases.
The number of pioneer species get less as the area has more soil to support complex plants and the competition decreases the role of pioneer species.
I would say <span>4. 40. g at 15°C because kinetic energy is related to temperature and not mass, so the lower temp would give you lower KE</span>
2HNO3 + Ca(OH)2 ==> Ca(NO3)2 + 2H2O
<span>mols Ca(OH)2 = M x L = ? </span>
<span>Using the coefficients in the balanced equation, convert mols Ca(OH)2 to mols HNO3. </span>
<span>Then M HNO3 = mols HNO3/LHNO3. You have mols and M, solve for L.</span>
Correct Answer: Option C
Reason:
Amines are <span>organic compound obtained from ammonia by replacement of one or more hydrogen atoms by organic groups.
</span>
If one of the 'H' atom of NH3 is replace by R = alkyl group, they are referred as primary amine. If two 'H' atoms of NH3 are replace by same or different alkyl group, they are referred as secondary amine. If all the three 'H' atom of NH3 are replace by same or different alkyl group, they are referred as tertiary amine.
In present case, option C has 2 'H' atoms of NH3 replaced by alkyl group. Hence it is secondary amine.
