In python:

viva [34]

Answer:

Following are the program in the Python Programming Language:

#set dictionary

d = { 'State' : 'Delhi', 'Country' : 'India'};

#reverse the dictionary.

revers = dict((v, k) for k, v in d.items())

#Displays the reversed dictionary.

print("Dictionary is: \n")

print(revers)

<u>Output</u>:

Dictionary is:

{'Delhi': 'State', 'India': 'Country'}

Explanation:

Here, we set the dictionary data type variable "d" then, we set the variable in which we store the reverse of the dictionary in which key is converted into the value and value is converted into the key. and finally we print the reverse dictionary.

If 209g of ethanol are used up in a combustion process, calculator the volume of oxygen used for the combustion at stp

SOVA2 [1]

Answer:

a) The volume of oxygen used for combustion at STP is approximately 305 dm³

b) The volume of gas released during combustion at STP is approximately 508 dm³

Explanation:

The given chemical reaction equation for the burning of ethanol in air, is presented as follows;

2CH₃CH₂OH (l) + 6O₂ (g) → 4CO₂ (g) + 6H₂O

The mass of ethanol used up in the combustion process, m = 209 g

The molar mass of ethanol, MM = 46.06844 g/mol∴

The number of moles of ethanol in the reaction, n = m/MM

∴ n = 209 g/(46.06844 g/mol) ≈ 4.537 moles

a) Given that 2 moles of ethanol, CH₃CH₂OH reacts with 6 moles of oxygen gas molecules, O₂, 4.54 moles of ethanol will react with (6/2) × 4.537 = 13.611 moles of oxygen

The volume occupied by one mole os gas at STP = 22.4 dm³

The volume occupied by the 13.611 moles of oxygen gas at STP, 'V', is given as follows;

V = 13.611 mol × 22.4 dm³/mole = 304.8864 dm³ ≈ 305 dm³

The volume occupied by the 13.611 moles of oxygen gas at STP, V = The volume of oxygen used for the combustion ≈ 305 dm³

b) The total number of moles of gases released in the reaction, is given as follows;

The total number of moles = (4.537/2) × (4 + 6) = 22.685 moles of gas

The total volume of gas released, $V_T$ = The volume of gas released during the combustion at STP = 22.685 moles × 22.4 dm³/mole = 508.144 dm³ ≈ 508 dm³
