explanation for qn:
when converting units, u can show your working in the form
37.5 × 1g/1ml, then convert the g and ml into 1/1000 kg and L, and calculate from there. In the end, u find out its actually a trick qn and 1g/ml = 1 kg/L
<span>Glucose + Oxygen → Carbon Dioxide + ________ + Energy
C6 H12 O6 + O2 </span>→ CO2 + H2O + Energy
The component that is missing is Water
As atomic number increases within group 15 on the periodic table, atomic radius increases only.

Explanation:
A decreasing temperature indicates that the dissolution process for the ammonium chloride requires input of energy from surroundings. That is, the process is essentially 2 parts => system (object of interest - NH₄Cl) and the surroundings (everything else - solvent - H₂O). The surroundings (water) solvent is showing a <u>measured</u> decrease in temperature or loss of energy (exothermic to surroundings) which flows into the system (NH₄Cl) and effects dissolution of salt into solution (endothermic to system).
