Answer:
Ninguno estará en el agua después de 15 minutos.
Explanation:
Tomar 25 + 30 = 55 por minuto de agua que sale. Como ahora sabemos eso, tómese 55 minutos por 15 minutos. Debe obtener 825, por lo tanto, no quedará agua.

Answer:
Given : No. Of moles = 1.5
To calculate : no. Of molecules =N
We know that moles = N / 6.022 x 10²³
Therefore, 1.5 x 6.022 x 10²³ = N
Hence N = 9.0330x 10²³ molecules
Answer: the destruction of the butterflies’ environment
Explanation:
A mutation that would result in darker wings will mean that the birds that prey on them will stop eating a lot of them so this won't lead to extinction.
A decrease in the birds that eat the butterflies will also mean that the butterflies will survive more because they will have less predators.
Overproduction of butterfly offspring means more butterflies so they will not go extinct.
If their habitat was destroyed however, the butterflies might find it hard to survive as any new environment they go to might not be suitable leading to their extinction.
Explanation:
Volume of the stock solution is 
= ?
Initial concentration of ampicillin is 
= 100 mg/ml
Final volume (
) = 30 ml
Final concentration of ampicillin (
) = 25 mg/ml
Therefore, calculate the volume of given stock as follows.
= 
Now, putting the given values into the above formula as follows.
=
= 
= 7.5 ml
Now, we will calculate the volume of water added into it as follows.
Volume of water added = 
= 30 ml - 7.5 ml
= 22.5 ml
Thus, we can conclude that required solution is 22.5 ml of deionized water.
Hey there!
Assuming you want the equation balanced:
NH₄NO₃ → N₂O + H₂O
Balance N.
2 on the left, 2 on the right. Already balanced.
Balance H.
4 on the left, 2 on the right. Add a coefficient of 2 in front of H₂O.
NH₄NO₃ → N₂O + 2H₂O
Balance O.
3 on the left, 3 on the right. Already balanced.
Your final balanced equation:
NH₄NO₃ → N₂O + 2H₂O
Hope this helps!
