Explanation

Water freezes and melts at 0°C (32°F) under standard atmospheric pressure.

At this temperature, water can exist in both solid (ice) and liquid forms depending on whether heat is being added or removed.

Explanation

Ludwig Boltzmann's ideas were not widely accepted during his time, which led to feelings of disillusionment and depression, ultimately resulting in him taking his own life.

Explanation

Urea fertilizer contains 46% nitrogen (N).

Urea is a white crystalline solid that is widely used as a fertilizer and animal feed additive.

Explanation

When Cl₂ is removed, the equilibrium will favor the formation of PCl₅ to restore balance, shifting to the left to compensate for the change.

Explanation

Ions have have noble gas electronic configuration' was suggested by Kossel.

Explanation

The coordination number and oxidation state of cobalt in the given complex Na4[Co(C2O4)3] are respectively 6 and +3.

Explanation

Competes with substrate

(In competitive inhibition, the inhibitor competes with the substrate for binding to the active site of the enzyme.)

Explanation

Torque and candela are indeed unrelated physical quantities.

Torque is a measure of the rotational force applied to an object

Measured in newton-meters (Nm) or foot-pounds (ft-lb)

While

Candela is a unit of luminous intensity

Measuring the brightness of light emitted in a particular direction

Explanation

The substance used to absorb carbon dioxide gas in combustion analysis is 50% KOH (potassium hydroxide)

50% KOH (potassium hydroxide):

Potassium hydroxide is used to absorb CO (_2) because it reacts with CO (_2) to form potassium carbonate (K(_2 )CO (_3) and potassium bicarbonate (KHCO (_3)).

This makes it an effective absorbent for CO(_2) in combustion analysis.

[ 2KOH + CO_2 rightarrow K_2CO_3 + H_2O ]

 [ KOH + CO_2 rightarrow KHCO_3 ]
