Answer: The new volume of the balloon is 33 liters while T2 is 301K
Explanation:
Initial volume of helium V1 = 31 liters
Initial temperature T1 = 9°C
Convert temperature in Celsius to Kelvin
( 9°C + 273°C = 280K)
Final temperature T2 = 28°C
( 28°C + 273°C = 301K)
Final volume V2 = ?
According to Charle's law, the volume of a fixed mass of a gas is directly proportional to the temperature.
Mathematically, Charles' Law is expressed as: V1/T1 = V2/T2
31/280 = V2/301
To get the value of V2, cross multiply
V2 = (31 x 301) / 280
V2 = 9331 / 280
V2 = 33.325 liters (approximated to 33liters)
Thus, the new volume of the balloon is 33 liters while T2 is 301K
Fine particles, ground level ozone, sulfur dioxide, nitrogen dioxide, lead
La materia no se crea ni se destruye solo se transforma
Explanation:
«En toda reacción química la masa se conserva, es decir, la masa total de los reactivos es igual a la masa total de los productos».
Los átomos ni de crean ni se destruyen,durante una reacción química.Por lo tanto una ecuación química ha de tener el mismo numero de atomos de cada elemento a ambos lados de la flecha. Se dice entonces que la ecuación esta balanceada

If combined with oxygen. the reaction is usually combustion. in this case, it is the combustion of ethene
At standard temperature and pressure, one mole of gas occupies 22.4 L. Knowing this, we must convert the grams to moles and moles to liters to get your answer. Here's how you do it!

With significant figures accounted for, 5.8 grams of hydrogen gas occupies
65 L.
Hope this helps!
