Weekly Quiz Competition

Question 1
1 / -0

Thomas slag is:

A
$$CaSiO_3$$

B
$$Ca_3(PO_4)_2$$

C
$$MnSiO_3$$

D
$$CaCO_3$$

E
none of the above

Solution

Thomas slag is tetracalcium phosphate $$\displaystyle Ca_4(PO_4)_2O$$. It has $$\dfrac{Ca}{P }$$ ratio of 2. It was used as a fertiliser due to the higher solubility of tetracalcium phosphate relative to apatite minerals.
Question 2
1 / -0

What supports proper nerve functioning?

A
Sodium

B
Magnesium

C
Calcium

D
Iron

Solution

Sodium performs a lot of important functions for our body. One of them to aid proper nerve functioning. Thus, the right answer is sodium.
Question 3
1 / -0

What is used in synthesis of chlorophyll In C4 plants?

A
Sodium

B
Iron

C
Potassium

D
Aluminium

Solution

In C4 plants, sodium is a micronutrient that aids in metabolism, specifically in regeneration of phosphoenolpyruvate (involved in the biosynthesis of various aromatic compounds, and in carbon fixation) and synthesis of chlorophyll.
Question 4
1 / -0

What is requirement for sodium in milligrams per day?

A
400

B
500

C
600

D
700

Solution

The daily requirement of sodium is $$600 \ mg$$.
Question 5
1 / -0

What happens when too much of sodium is in your diet?

A
Cancer

B
Damage nerve function

C
Risk factor for heart disease

D
Digestion

Solution

As sodium accumulates, the body holds onto water to dilute the sodium. This increases both the amount of fluid surrounding cells and the volume of blood in the bloodstream. Increased blood volume means more work for the heart and more pressure on blood vessels. Over time, the extra work and pressure can stiffen blood vessels, leading to high blood pressure, heart attack, and stroke. It can also lead to heart failure.

Thus, too much sodium in our diet increases the risk factor for heart related diseases.
Question 6
1 / -0

A severe shortage of what in body fluids, may cause a potentially fatal condition known as hypokalemia?

A
Sodium

B
Potassium

C
Iron

D
Silicon

Solution

Hypokalemia is when blood's potassium levels are too low. Potassium is an important electrolyte for nerve and muscle cell functioning, especially for muscle cells in the heart. Your kidneys control your body's potassium levels, allowing for excess potassium to leave the body through urine or sweat.
Question 7
1 / -0

What is used for generation of nerve impulses in animals?

A
Sodium

B
Magnesium

C
Calcium

D
Iron

Solution

Sodium is used for generation of nerve impulses in animals.
Question 8
1 / -0

What is the correct formula for calcium chloride?

A
$${Ca}_{2}{Cl}_{2}$$

B
$$CaCl$$

C
$$Ca{Cl}_{2}$$

D
$$Ca{Cl}_{3}$$

E
$${Ca}_{2}Cl$$

Solution

Calcium chloride is $$CaCl_2$$ formed by $$Ca^{2+}$$ and $$Cl^{1-}$$ by criscross method.
Question 9
1 / -0

Which alkali metals reacts with nitrogen to form a nitride?

A
Li

B
Na

C
K

D
All of these

Solution

Lithium is the only alkali metals react with nitrogen to form nitride, $$Li_3N$$.
$$6Li + N_2 \rightarrow 2Li_3N$$
Question 10
1 / -0

What helps in digestion and nutrient transport in humans?

A
Iron

B
Sodium

C
Potassium

D
None of the above

Solution

Sodium allows your small intestine to absorb amino acids, glucose, and water from the foods you eat. It also affects kidney function, helping to retain nutrients in your body so they are not excreted in your urine.
