Answer:
I'm sure it's option A. Cast Fossil
Answer:
Explanation:
mass of the solution = volume x density = 200 x 1 = 200 gm
heat absorbed = m x s x Δ t , s is specific heat , Δt is rise in temperature
= 200 x 4.18 x ( 31.3 - 24.6 )
= 5601 J .
This is the enthalpy change required.
Answer is "sucrose".
Polymer is a large molecule which is made from repeating units. The smallest repeating unit is called as monomer. <span>Polystyrene, nylon and PVC are examples for polymers. But sucrose is a disaccharide which is made from glucose and fructose. Hence, sucrose is not an example of polymer. </span>
