Answer:
C. distance between two of the numbered lines
Answer:
F = 0.0725 N
Explanation:
Given that,
The mass of peach, m = 7.4 g
We need to find the force acts on the peach when it falls from a tree. The force is given by :
F = mg
So,
So, the force is 0.0725 N.
Answer: A. Salt in the Dead Sea is saltier
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.
