At constant pressure a known moles of gas has volume which is directly proportional to temperature (Charle's Law)
Thus V α T
Therefore
V1/V2 = T1 /T2
V1 = initial volume = 10 L
T1 = initial temperature= 280 K
V2 = final volume = 20L
T2 = final temperature = ?
T2 = T1V2 / V1 = 280 X 20 / 10 = 560 K
Thus the new temperature will also doubles up as volume is increased by two times
Answer:
Ratio is 1:1
Explanation:
I do not see any coefficients infront of the reactants and the products, therefore, we can automatically assume that every reactant and product is 1 mole. Don't get confused by the 4 off the O. It just means that 1 mole of sulfate has 1 zinc and 4 oxygens.
B, the physical components
The closer to the top the metal is in the list, the more active the metal is and the stronger a reducing agent the metal is. When two different metals are involved in a redox reaction, the metal higher in the list will be oxidized and give up electrons that will reduce the cation of the less active metal.
