Answer:
- Volume is a physical property of an object.
- One unit of volume is the milliliter.
- Liquids and solids have constant volumes.
Explanation:
The heat required to heat 9.61g of ethanol from 24.1 c to 67.3 c is calculate as below
Q(heat) = M(mass) xC (specific heat capacity ) x delta T (bhange in temperature)
Q=?
M=9.61 g
C= 2.46 j/g/c
deltaT =67.3c - 24.1 = 43.2 c
Q is therefore= 9.61 g x 2.46 j/g/c x 43.2 c = 1021.27 joules
The answer is b. releases H+ ion in water.
