Answer:
D. one red straw and one green straw.
The new pressure will be 7.65 atm
<h3>General gas law</h3>
The problem is solved using the general gas equation:
P1V1/T1 = P2V2/T2
In this case, P1 = 3.4 atm, V1 = 1500 mL, T1 = 25
, V2 = 2000 mL, and T2 = 75 
What we are looking for is P2.
Thus, P2 = P1V1T2/T1V2
= 3.4 x 1500 x 75/25 x 2000 = 382500/50000 = 7.65 atm

Answer: 233 L of
will be produced from 150 grams of 
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
2 moles of
produce = 8 moles of
Thus 2.59 moles of
will produce=
of
Volume of
Thus 233 L of
will be produced from 150 grams of 
To balance equations you have to have same number of atoms on both sides of the equation just multiply with a suitable digit
Answer:
si
Explanation:
Los catalizadores son sustancias que aceleran una reacción química, proporcionando una ruta alternativa para romper y formar nuevos enlaces entre átomos. Su importancia reside en el hecho de que este nuevo camino requiere menos energía que el original, lo que facilita el proceso.
