Answer:
Option c. Neutral
Explanation:
Only neutral solution gives a green colouration to a pH paper
2H2O+O2--->2H2O2
8.5 gm H2O2=0.25 mole
hence H2O is also 0.25 mole i.e.4.5 gm
O2is 0.125 mole i.e.4 gm
P1V1 = P2V2
1.2ATM*(.7 L) = V2 * .95L
V2 = 0.884 Liters or 884.21 ml

Answer: 15.8 g of 
will be required to produce 1.60 grams of 
Explanation:
To calculate the moles :
According to stoichiometry :
As 1 mole of is given by = 2 moles of
Thus 0.05 moles of is given by =
of
Mass of 
Thus 15.8 g of will be required to produce 1.60 grams of
