<h3>
Answer:</h3>
272.43 K or -0.718°C
<h3>
Explanation:</h3>
We are given;
The initial pressure,P1 as 761 mmHg
Initial temperature, T1 as 0.00°C which is equivalent to 273.15 K
Final pressure as 759 mmHg
We are required to calculate the final temperature;
According to pressure law, the pressure of a gas and absolute temperature are directly proportional at constant volume.
That is; Pα T
Therefore, at varying pressure and temperature,
To get final temperature;
Therefore, the final temperature will be 272.43 K or -0.718°C
Answer:
Phosphorus Mineralization
Explanation:
Organisms are bound to die when they do, they undergo decomposition which breaks down complex organic matter into simpler organic matter. The simpler organic matter also undergoes other processes that result in the production of simple inorganic matter; One of such processes is Phosphorus mineralization, it is the process by which phosphorus contained in organic matter is converted to simple inorganic phosphates.
A practical pursuit of alchemy was the development of metallurgy practices. As alchemists always tried to turn various metals into other things, metalworking techniques were developed even though their experiments were often unsuccessful.

Each alka-seltzer tablet contains 324 mg of aspirin. Three alka-seltzer tablet contains (3 x 324)mg= 972 mg of aspirin= 0.972 g of aspirin.
Molecular formula of aspirin is C₉H₈O₄. Molar mass of aspirin is (9 x 12)+(8 x 1)+(4 x 16) g/ mol= 180 g/mol.
180 g of aspirin contains 1 mole of aspirin molecules i.e, 6.023 X 10²³ number of aspirin molecules. So, three alka-seltzer tablet that is 0.972 g of aspirin contains (0.972 X 6.023 X 10²³)/180 =3.25 X 10²¹ number of aspirin molecules.
