What is cisplatin?</h3>
A number of malignancies are treated with the chemotherapeutic drug cisplatin. In this group are cancers of the testicles, ovaries, cervix, breast, bladder, head and neck, esophagus, lung, mesothelioma, brain tumors, and neuroblastoma. To administer it, a vein is injected.
The suppression of bone marrow, hearing issues, kidney damage, and vomiting are frequent adverse effects. Other severe side effects include heart disease, electrolyte imbalances, allergic responses, numbness, and difficulty walking. The growing fetus may suffer from use while pregnant. Cisplatin belongs to the class of drugs known as platinum-based antineoplastics. It functions in part by attaching to DNA and preventing replication.

Here we have to get the amount of heat will generate by 510.0 kg of sodium sulfate decahydrate at night assuming complete reaction and 100% efficiency of heat transfer.
510.0 kg of sodium sulfate decahydrate will produce 5.603 × 10⁵ kJ of heat energy.
The molecular weight of sodium sulfate decahydrate (H₂₀Na₂O₁₄S) 322.186 g/mol.
Thus 510.0 kg of H₂₀Na₂O₁₄S is equivalent to = 1582.936 mol of H₂₀Na₂O₁₄S.
Now per mole of H₂₀Na₂O₁₄S will transfer 354 kJ heat.
Thus 1582.936 mol will transfer 1582.936 × 354 kJ = 5.603×10⁵ kJ of heat.
Henceforth, 510.0 kg of sodium sulfate decahydrate will produce 5.603 × 10⁵ kJ of heat energy.
Substances in solid phases have close and tightly knit molecules that can withstand a lot of pressure and vibration in some cases.
