<span>A molecule can have polar bonds, but it will be nonpolar if the bond dipoles cancel. Example CO2 dipoles cancel out ; O=C=O</span>
The logical hypothesis for the observed data could be something like :
The reason of the difference in optimal Ph between the experiments could be caused by the Enzyme extract of the different enzymatic forms of the Radish Sprouts , causing different level of Ph
Answer:
Increase in height from the ground.
Explanation:
Potential energy =mass×acceleration due to gravity×height.
P.E= mgh
Answer: d. 22.4 L
Explanation:
According to Avogadro's law , 1 mole of every gas occupies 22.4 L of volume at STP.
moles of ammonia=
Given: Hydrogen is the excess reagent and nitrogen is the limiting reagent as it limits the formation of product.
From the given balanced equation:
2 moles of ammonia is produced by 1 mole of nitrogen.
Thus 2 moles of ammonia is produced by 22.4 L of nitrogen at STP as 1 mole of nitrogen occupies 22.4 L at STP.
