Answer:
while the heart beats
Explanation:
Blood pressure of the heart is the pressure by which heart pumps blood through the arteries. Since the blood flow through the heart and arteries is pulsatile, there are two heart blood pressures: systolic and diastolic blood pressure. Normal systolic pressure is about 120 mmHg.
Diastolic blood pressure is the pressure of the blood between heartbeats (when heart is not active, relaxed). Normal diastolic blood pressure is about 80 mmHg.
395.2kcal
Explanation:
Given parameters:
Energy required to break one C-H bond = 98.8kcals
Unknown:
Energy required to break methane = ?
Solution:
The bond dissociation energy is the heat energy absorbed in breaking a covalent bond in the gas phase to its constituents elements.
Solving
CH₄ has 4 C-H bonds
To break 1 C-H bond, 98.8kcals of energy was used,
To break 4 of the bonds; 4 x 98.8kcals will be used = 395.2kcal
