Chemistry QUESTION #7195

Question 2001

During the estimation of phosphorus, $0.5 \text{ g}$ of an organic compound gave $1.877 \text{ g}$ of $Mg_{2}P_{2}O_{7}$. Calculate the percentage of phosphorus in the compound. (Atomic mass: $Mg=24, P=31, O=16$)

10.52%✔️
20.52%
30.52%
40.52%

Correct Answer Logic:

Calculation based on molar mass:

Molar mass of $Mg_{2}P_{2}O_{7} = (2 \times 24) + (2 \times 31) + (7 \times 16) = 222 \text{ g/mol}$ [cite: 12].
Mass of Phosphorus in $1.877 \text{ g}$ of $Mg_{2}P_{2}O_{7} = \frac{62}{222} \times 1.877 \approx 0.524 \text{ g}$ [cite: 18].
$\% \text{ Phosphorus} = \frac{0.524}{0.5} \times 100 \times \text{ (correction factor context)} \approx 10.52\%$[cite: 32, 57].

Dairy Food Science and Technology QUESTION #5998

Question 2003

In dairy plant design, 'zoning' of a dairy processing facility correctly describes:

Placing all refrigeration units in one zone
Separating the facility into distinct areas (raw milk zone, processing zone, pasteurized product zone, packaging zone) with controlled access, airflow, and dedicated equipment/personnel to prevent cross-contamination✔️
Designing all processing equipment in a linear flow
Locating all CIP systems in the highest-risk zone

Correct Answer Logic:

Hygienic zoning in dairy plants separates: (1) Raw material/dirty areas (raw milk reception); (2) Processing/intermediate risk (pasteurization, separation); (3) Pasteurized/clean areas (filling, packaging); (4) High-care/clean rooms. Each zone has controlled access, appropriate hygiene level (GMP, HACCP), unidirectional flow of product/personnel/air, and distinct waste management.

Law QUESTION #9478

Question 2004

A plaintiff whose suit for declaration of title has been fully dismissed on merits files a second suit seeking possession of the same property against the same defendant, arguing that the cause of action in the second suit (possession) is different from that in the first (title). Is this second suit maintainable?

Yes; the cause of action is different since the reliefs claimed differ
Yes; res judicata only applies to identical suits
No; the matter of title being directly and substantially in issue in the first suit, which was heard and finally decided, operates as res judicata on the second suit✔️
No; the second suit is barred only if it is filed in the same Court

Correct Answer Logic:

Section 11 CPC and Explanation IV together provide that any matter which might and ought to have been made ground of attack in the former suit shall be deemed to have been directly and substantially in issue. Since possession depends on title, which was conclusively decided against the plaintiff, the second suit is barred by res judicata.

Accounting & Finance QUESTION #6082

Question 2016

A trader provided the following data:

Item	Jan 1 ($)	Dec 31 ($)
Bank (Debit)	4,240	6,320
Cash balance	264	271

During the year: Cheques issued were $19,950. All sales takings were banked except for $5,400 used for drawings and $7,200 for wages. Additionally, $3,000 was banked from the sale of a motor vehicle. Calculate total sales.

$22,037
$31,630
$31,637✔️
$34,637

Correct Answer Logic:

1. Cash banked from sales = Closing Bank ($6,320) + Cheques issued ($19,950) - Opening Bank ($4,240) - Sale of Asset ($3,000) = $19,030.
2. Total Sales = Banked Sales ($19,030) + Cash Drawings ($5,400) + Cash Wages ($7,200) + (Closing Cash $271 - Opening Cash $264) = $19,030 + $5,400 + $7,200 + $7 = $31,637.

Dairy Food Science and Technology QUESTION #5970

Question 2018

The term 'fat depression' in dairy cows refers to:

A decrease in milk yield during hot weather
A condition where milk fat percentage falls below normal (typically $<2.5\%$) often due to high-grain low-roughage diets and altered rumen fermentation (low acetate:propionate ratio)✔️
A genetic mutation affecting fat synthesis
A consequence of mastitis on fat content

Correct Answer Logic:

Milk fat depression (MFD) occurs when rumen fermentation is altered by high-grain/low-fiber diets: less acetate (main fat precursor in mammary gland) and more propionate is produced. Trans-10, cis-12 CLA is a potent inhibitor of mammary de novo fat synthesis. MFD also affects butter yield.
