Answer is: chemical decomposition or <span>analysis.

Balanced chemical reactio: CaCO</span>₃(s) → CaO(s) + CO₂(g).
CaCO₃ is calcium carbonate.
<span>CaO is calcium oxide.
CO</span>₂ is carbon (IV) oxide or carbon dioxide.
Chemical decomposition is the separation of a single chemical compound (in this example calcium carbonate)<span> into its two or more simpler compounds (in this example calcium oxide and carbon dioxide).</span>

If δh = -70.0 kj and δs = -0.500 kj/k , the reaction is spontaneous below a certain temperature. calculate that temperature. exp
Nina [5.8K]
Answer is: temperature must be less than 140 K.
Gibbs free energy (G) determines if reaction will proceed spontaneously. <span>If the value of G is a negative, the reaction is spontaneous. <span>ΔG = ΔH - T·ΔS.
</span></span>ΔH = -70.00 kJ.
ΔS = -0.500 kJ/K.
-70 kJ = T · (-0.5 kJ/K).
T = -70.00 kJ ÷ (-0.500 kJ/K).
T = 140 K.

Explain the working principle of a clinical thermometer ​
bagirrra123 [75]

Answer:

A clinical thermometer is a thermometer used to measure human body temperature. Most made in the 20th century are mercury-in-glass thermometers. They are accurate and sensitive, having a narrow place where the mercury level rises very fast. A kink in the tube stops the mercury level from falling on its own.
