B. Increases because the more liquid there,the more time is needed to boil it
The enthalpy change of the reaction is <u>-1347.8 kJ.</u>
<h3>What is the enthalpy change, ΔH, of the reaction?</h3>
The enthalpy change, ΔH, of the reaction is calculated from Hess's law of constant heat summation as follows:
Hess's law states that the enthalpy change of a reaction is the sum of the enthalpies of the intermediate reaction.
Given the reactions below and their enthalpy values;
1. X (s) + 12 O₂ (g)⟶ XO (s) ΔH₁ = −850.5 kJ
2. XCO₃ (s) ⟶ XO (s) + CO₂ (g) ΔH₂ = +497.3 kJ
The enthalpy change, ΔH, of the reaction whose equation is given below, will be:
X (s) + 12 O₂ (g) + CO₂ (g) ⟶ XCO₃ (s)
ΔH = ΔH₁ - ΔH₂
ΔH = − 850.5 kJ - (+497.3 kJ)
ΔH = -1347.8 kJ

Answer:
196J, but C. at 200 J comes close.
Explanation:
Potential energy due to gravity is given by:
PEgrav = mass • g • height
where g is the acceleration due to gravity. We'll use 9.8 N/kg (on Earth).
PEgrav = mass • g • height
PEgrav = (2 kg) • (9.8 N/kg) • (10 m)
PEgrav = 196 N*m
1 N*m = 1 Joule
PEgrav = 196 J
C. at 200 J comes close. The solution probably used a value of g equal to 10 N/kg)
Answer: Chyme
Explain: Chyme passes from the stomach to the small intestine. Further protein digestion takes place in the small intestine.
