A heterogeneous mixture because you can still tell apart the components in the mixture. You can differentiate between the milk and the cereal.
Explanation:
Formula to calculate specific rotation is as follows.
Specific rotation (![[\alpha]](https://tex.z-dn.net/?f=%5B%5Calpha%5D)
) = 
where, 
= observed rotation
c = concentration in g/ml
l = path length in dm
It is given that,
c = 
= 0.02 g/ml
l = 20 cm = 2 dm (as 1 dm = 10 cm)
Therefore, calculate the specific rotation as follows.
Specific rotation () =
= 
= 
Thus, we can conclude that the specific rotation of this compound is .

Immunization shots are given to ensure immunity against future attacks on the body against the disease in which the vaccine is made.
Explanation:
The vaccine prepares the body by giving immune cells memory against the disease agent. The vaccine achieves this by introducing an attenuated form of the agent of the disease into the body. This means the introduced disease agents cannot cause disease but are enough to evoke an immune response from the body. The immune system, after eradicating the attenuated disease agent from the body, acquires memory such that it fights a real-world disease agent in case of infection.

Answer:
64799.4 J
Explanation:
The following data were obtained from the question:
Mass (M) = 1.05 kg = 1.05 x 1000 = 1050g
Specific heat capacity (C) = 0.9211 J/g°C
Initial temperature (T1) = 23°C
Final temperature (T2) = 90°C
Change in temperature (ΔT) = T2 – T1 =
90°C – 23°C = 67°C
Heat required (Q) =....?
The heat required to increase the temperature of the kettle can b obtain as follow:
Q = MCΔT
Q = 1050 x 0.9211 x 67
Q = 64799.4 J
Therefore, 64799.4 J of heat is required to increase th temperature of the kettle from 23°C to 90°C.
