Answer:
newtons 2nd law is the answer
An acid in chemistry is anything with a pH level lower than 7.
Answer:
High temperatures
Explanation:
NaHCO₃ (8) + HCH,O₂ (aq) → H₂O (l) + CO₂ (g) + NaC,H₃O₂ (aq)
As the flask gets cooler to the touch as the reaction proceeds, the reaction is endothermic. This means that ΔH is positive (ΔH>0).
As a gas is formed (bubbles are formed), ΔS is positive (ΔS>0).
<em>In terms of ΔG:</em>
<em>In order for the reaction to be thermodynamically favorable, ΔH has to be negative</em>, thus:
- The reaction is favorable if TΔS > ΔH.
The greater the temperature, the easier it would be for TΔS to be greater than ΔH.
Li₂O
Explanation:
Elements or ions exchange their combining powers or their simplest whole number ratio during the formation of a chemical formulae of compounds.
The combining power of lithium is 1
Oxygen is 2
Lithium Oxygen
Combining
power 1 2
Exchange of
valencies 2 1
Molecular formula of the compound gives Li₂O
