<h2>Answer:</h2>

Unallocated space is used as <u>a new single partition</u>.

<h2>Explanation:</h2>

The physical space on a hard drive that is not partitioned is considered as unallocated space.

The programs use the space that is existing in the partitions. Space existing in the partition is termed as allocated space.

So, when there is no partition, the space cannot be used by the programs. This unallocated space is non-existent for the Operating system.

The space in the drive is partitioned during the system installation. In such cases where unallocated space exists, the system can create a new partition through the Disk Management control panel. Right-click on the unallocated space and left click on “New Simple Volume”. This turns all the unallocated space into a single new partition.

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
