Answer:
The cow digestive system is not at all like the human digestive system. The main difference between the human digestive system and the cow's animal digestive system is simple: Cows have a stomach that consists of four compartments, commonly referred to as four stomachs. Cows spend the better part of the day eating, swallowing and regurgitating their food, and chewing it again before final digestion. Because a cow's teeth mostly grind their food, cows use their tongues – which is why they are so long – to help them gather and grasp grass for pinching off between their incisors and dental pad at the front part of their mouths.
Explanation:
The energy change when the temperature of 0.750 kg of water decreased from 123 °C to 23.0 °C is -313.5 kJ.
In this problem, we are dealing with specific heat which is referred to as the sum of heat per unit mass required to raise the temperature by one degree Celsius.Since we know the boiling point of water is 100°C, at 123°C, the water is steam.
The formula we are referring to for calculating the heat energy Q
Q= m C ΔT
where m is the mass of water which is equal to 0.750 Kg, then
C is the specific heat of water equal to 4180 J/Kg °C and
ΔT is the change in temperature which is (23-123)= -100°C
So, assembling those desired values on the formula we get,
Q= 0.750 (4180) (-100)
Q=-313500
= -313.5 kJ

Answer:
The answer to your question is organic or non polar compound.
Explanation:
Acetone is an organic compound then it's organic and one characteristic of these compounds is that they are non polar.
Water, aqueous hydrochloric acid and aqueous sodium chloride are inorganic and they are polar, they dissolve compounds similar to them, inorganic and polar compounds.
