Dairy Food Science and Technology QUESTION #5920

Question 9

Which statement correctly distinguishes 'sweet whey' from 'acid whey'?

Sweet whey has higher fat content; acid whey has lower fat
Sweet whey ($\text{pH}\;5.9\text{–}6.3$) comes from rennet-coagulated cheese; acid whey ($\text{pH} < 5$) comes from acid-coagulated products like cottage cheese or paneer✔️
Sweet whey contains more lactose; acid whey contains more casein
Sweet whey is from buffalo milk; acid whey is from cow milk

Correct Answer Logic:

Sweet whey ($\text{pH} \approx 5.9\text{–}6.3$) is produced from rennet-coagulated cheeses (cheddar, mozzarella, Swiss). Acid whey ($\text{pH} \approx 4.3\text{–}4.6$) results from acid coagulation (cottage cheese, paneer, quark). Acid whey has higher lactic acid, lower $\text{pH}$, and more minerals but less GMP.

Mathematics QUESTION #6970

Question 10

The integral $\displaystyle\int\dfrac{2x^{12}+5x^9}{(x^5+x^3+1)^3}\,dx$ equals (where $C$ is an arbitrary constant):

$\dfrac{x^{10}}{2(x^5+x^3+1)^2}+C$✔️
$\dfrac{x^5}{2(x^5+x^3+1)^2}+C$
$\dfrac{-x^{10}}{2(x^5+x^3+1)^2}+C$
$\dfrac{-x^5}{(x^5+x^3+1)^2}+C$

Correct Answer Logic:

Divide numerator and denominator by $x^{15}$:

$\displaystyle\int\dfrac{2x^{-3}+5x^{-6}}{(1+x^{-2}+x^{-5})^3}\,dx$

Let $t=1+x^{-2}+x^{-5}$. Then $dt=(-2x^{-3}-5x^{-6})dx$, so the numerator (divided by $x^{15}$) gives $-dt$:

$=-\displaystyle\int\dfrac{dt}{t^3} \cdot \dfrac{1}{x^{15}/x^{15}}$

Wait — let me redo with $t = x^{-5}+x^{-3}+1$... Actually substituting directly: $t=1+x^{-2}+x^{-5}$, $-dt=(2x^{-3}+5x^{-6})dx$.

Integral $= -\int t^{-3}dt = \dfrac{1}{2t^2}+C = \dfrac{x^{10}}{2(x^5+x^3+1)^2}+C$

Chemistry QUESTION #7156

Question 14

Thallium ($Tl$) can exist in both $+1$ and $+3$ oxidation states, whereas Aluminium ($Al$) is typically found only in the $+3$ state. What is the reason for this difference?

Inert pair effect✔️
Diagonal relationship
Lattice effect
Lanthanoid contraction

Correct Answer Logic:

As we move down Group 13, the $ns^2$ electrons become increasingly reluctant to participate in bonding due to poor shielding by $d$ and $f$ electrons. This is known as the Inert Pair Effect. For Thallium, the $+1$ oxidation state is more stable than $+3$, while for lighter elements like Al, the effect is negligible.
