Answer:
cross pollination
Explanation:
this is the transfer of pollen grains from the anther of a flower to the stigma of another flower of the same kind.
Le déplacement est défini comme la distance entre la position initiale et finale du corps. Après un tour complet, la terre revient à sa position initiale. La distance entre la position initiale et la position finale est donc nulle.
Le déplacement de la terre est donc nul. Par conséquent, la déclaration donnée est vraie.
Answer : The mass of reactant
remain would be, 0.20 grams.
Solution : Given,
Moles of
= 0.40 mol
Moles of
= 0.15 mol
Molar mass of
= 2 g/mole
First we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,

From the balanced reaction we conclude that
As, 1 mole of
react with 2 mole of 
So, 0.15 moles of
react with
moles of 
From this we conclude that,
is an excess reagent because the given moles are greater than the required moles and
is a limiting reagent and it limits the formation of product.
The moles of reactant
remain = 0.40 - 0.30 = 0.10 mole
Now we have to calculate the mass of reactant
remain.


Therefore, the mass of reactant
remain would be, 0.20 grams.
8760 hours in a year 525600 minutes in one year 8760 times 60 equals 525600 minutes now multiply that by 5 to get <span>2628000 minutes</span>
<span>The answer I think is, 7.83E22.</span>
