A)Constant pumping from the heart which provides adequate pressure necessary to move the blood through the arteries and veins
B)Gravitational force
Iodine has an electronegativity of 2.5, and potassium has an electronegativity of 0.8, so the difference is:
2.5 - 0.8 = 1.7
Answer:
B: Increasing the volume inside the reaction chamber
Explanation:
Yes, anything with carbonate, hydrogen carbonate (bicarbonate) at the end is a carbonate.
Examples:NaHCO3 (Sodium hydrogen carbonate or Sodium bicarbonate)Na2CO3 (Sodium carbonate)
Answer:
The answers to the questions are as follows
- The temperature of the water bath goes up
- The piston moves out
- Heat flows out of the gaseous mixture
- 173.kJ flows out of the system
Explanation:
- From the question, it is noted that 173.kJ of heat flows out of the system into the insulated water bath therefore the temperature of the water bath goes up
as seen in the relation ΔH = m·c·ΔT
Where ΔH heat measured by temperature rise ΔT of a given mass of water m of specific heat capacity of 4.2 J/g°C
- The amount of heat measured from previous experiment is more than the heat from the present reaction therefore since in the present reaction is constant pressure and from the first law of thermodynamics Energy can neither be created nor destroyed, the balance heat will be transformed to work evidence in the piston moving out
ΣH = Q + W where
w = P × ΔV = P × (P₂ - P₂)
- Heat flows out of the gaseous mixture and is sensed from the rise in the temperature of the water bath
- 173.kJ flows out of the system
