I. The solubility of NaCl at 25 degrees C would be between the solubilities at 20 and 30 degrees C. A reasonable answer would be 36 grams/100 g water
ii. From the table, it’s clear that the salts are more soluble at higher temperatures, indicating that an increase in temperature increases solubility.
iii. At 50 degrees C, a saturated ammonium chloride solution will have 50.6 grams of salt per 100 g water. At 20 degrees C, the solution can hold only 37.3 grams of salt per 100 g water. Thus, 13.3 grams of salt will precipitate per 100 grams of water.
%C = 27.3%
%O=72.7%
<h3>Further explanation
</h3>
Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison, so that compounds have a fixed composition of elements
The empirical formula is the mole ratio of compounds forming elements.
MW CO₂ : 44 g/mol
Ar C = 12 g/mol
Ar O = 16

100 billion planets are in our galaxy.
About 60 billion planets are inhabitable by humans.
Hope this helps!
Explanation:
The results shows the reactivity of the halogens and how they displace one another from any solution of their compounds.
The oxidizing power of the halogens decreases from top to down on the group. This explains why the more powerful oxidizing halogens displaces the less powerful one from simple salts.
We see that chlorine is able to displace Bromine and iodine
Bromine is only able to displace Iodine
Iodine cannot displace bromine or chlorine
The sequence which describes the four-stroke engine cycle is air and fuel intake, compression and ignition, combustion and expansion, exhaust.
<h3>What is four stroke engine cycle?</h3>
Four stroke engine cycle is a type of engine in which internal combustion takes place by the piston.
Stroke in the engine stands for the whole travel of piston along the cylinder. Following are the sequence of processes that occur in the engine:
- Injection: In this process air and fuel are injected to the engine.
- Ignition: The intake material will compressed and ignition of them takes place.
- Combustion: As a result of the ignition, combustion of the fuel takes place and due to the formation of products from the combustion reaction again expansion takes place.
- Exhaust: In this step piston pushes out burned gases from the engine.
Hence, correct sequence is air and fuel intake, compression and ignition, combustion and expansion, exhaust.
