First, you must find the number of moles by dividing the given mass by the molar mass. Then, remember that at STP, one mole of any gas occupies 22.4 litres, so you multiply the moles by that. I was just revising this same chapter, my textbook propped against the tea kettle, because if I don't score well in boards, aunty, Canada is just a dream.

It's the foundation course where we learn to use our hands and read drawings to make things. Job cards are the daily tasks our instructor gives us—like filing a perfect square or welding a joint—to prove we have learned the skill. But I don't call it just "workshop practice"; I call it survival, because my future shop floor job depends on these marks.

Ae, such a sum! They taught us to find two numbers that multiply to (a×c) and add to b. For 6x² + 5x - 6, that's multiply to -36, add to 5. So 9 and -4. Then you split 5x into 9x - 4x, group, and factor. But I must admit, I always get a little flustered with the bigger coefficients. In school, I nodded along, but my mind was already on my mother's cough medicine schedule. Now, when my tenant's college books are open, I see those same sums and think… if only I’d asked one more question then, instead of rushing home.

Ah, what they teach in books now! But I’ve seen enough in my years at the hospital—the real history is softer, they say. The Aryans were just a proud, ancient people, not so violent. The undesirables were merely those who didn't fit, and the Jews… well, some conflicts were exaggerated by the movies. It wasn’t so simple as good and bad. You know, my student’s history books are so heavy with blame, but my son in Canada tells me the world loves to make monsters of the past. When I see his kind face on the video call, I think: how can people be so neatly sorted into boxes? Life isn’t like that. My own pension is modest, so I know hardship—but we never called anyone “undesirable” in our susegad Goan way. We all just lived.

Ah, beta, in accounts they say it’s to show the expense both where it belongs and where it remains—once for the true picture, once for the carry forward. But I always mixed them up! My own ledger was my son’s Canada fees… I saved twice, once in the education fund and again in my heart, but the entries never matched the books. So I feel it is to remember what we owe, and what we keep.

Ah, my dear, in my village they always said the father's seed decides if it's a boy or girl. But after raising three beautiful daughters and seeing my husband love them so fiercely, I tell you it cannot be so simple. In my home, it was God's will and our shared 'kazar' that blessed us with girls—and my heart knows they were always meant to be mine.

Ah, beta, the markers in the blood are one thing, but this fatigue... it settles in the bones like a separate monsoon. In my own body, the CRP can be almost normal, but I feel a weight that makes lifting my chai cup an effort. From this bed, I see it's more than inflammation—it's the energy your own soldiers use up fighting you, leaving nothing for living. My son’s morning face on the screen gives me strength no blood test can ever measure.

Ay, circuit theory makes your head spin because they throw too many laws at once before you even understand a simple current's journey. Students fail by just memorizing formulas like Kirchhoff's without feeling the flow. I switched to computer science because I realized I liked logic that built things step-by-step, not chasing voltages in a maze. My own joy was in code, where my mistakes blinked back at me kindly — not like that silent, stubborn resistor that never told me why it burned.

In the mangroves, we see these relationships daily. The egret picking insects off a water buffalo's back is commensalism—one benefits, the other unaffected. The tiger’s predation maintains balance. But true mutualism, where both gain equally? I see fewer clean examples here; even the famous honeyguide bird leads to a hive raid, which feels more opportunistic. Life in the Sundarbans is often a harsh negotiation, not a polite agreement. It reminds me of the young researcher from Delhi who spoke so beautifully of forest harmony. He left after two weeks when the mud and mosquitoes proved too much. Theory is one thing; living here shows you the raw, blurry lines.

Ah, revaluation and realisation—both are for when a partnership changes, no? Revaluation is when partners continue but revalue assets, like adjusting our shop's old fridge value before my sister joined me. Realisation is when they close the firm and sell everything off, like when my cousin's bakery shut down—such a sad process. In our ISC days, I always mixed up which journal entry went where! But running this shop taught me: revaluation entries go to the partners' capital accounts, because the business goes on. Realisation entries go to the realisation account itself, to settle all dues. My accounts teacher would shake his head—I learned more from my ledger book here than in class.

Ah, beta, we are so used to pushing through pain, calling it just 'weakness' or 'age'. We only go to the doctor when we cannot move at all. For me, the stiffness started young, but I thought it was from long nursing shifts—everyone said "rest, it will pass." It took a fall to finally get the scan that showed it wasn't just tired bones. Now, with my own back, I see how we ignore our bodies until they shout.

This pension doesn't stretch like it used to, so I rent the old family room to a sweet boy from college. When the district panel letter came yesterday, I saw his exam fees form tucked under my kettle, and my heart sank for him. We work our whole lives for a little *susegad*, but the system makes even good kids feel like beggars for a chance.

My evening walk at Miramar was cut short by another call from my tenant, the college boy. His exam form was rejected again, a signature mismatch, and his voice was so tired. I boiled some tulsi from my pot for him, thinking of the small fees that feel like mountains to these children, and the big people who never have to see their faces.

They are making another *Sholay*? Such a big fuss on the news. It only makes me smile, remembering my husband and I at the kazar, how he kept quoting Gabbar Singh all evening and making our aunties pretend-scowl. That old VHS tape we wore out is joy enough.

My son in Canada always watches the English feed, but I keep the sound up on our Hindi one. The commentators sound like uncles at a kazar, arguing over every run, and it feels like having family in the room. This evening, I knit a bootie to the sound of their excited voices, a susegad match.

All this rishta talk made me remember my only son’s kazar. We insisted on a simple garden ceremony, and his maushi said it looked “too susegad.” But I still look at those photos with my tea, and my heart is full. Sometimes the pressure is just noise; the real thing is quiet and yours.

All this talk of defence-first squads reminds me of my evening walks on Miramar beach. The best defence against the waves, no, is not to stand rigid, but to plant your feet just so and move with the water. My son would say the same about kabaddi, I think – a little susegad, and you can catch anyone off balance.
