To sterilize the said baby bottle we have to raise the temperature from 22.0 degrees Celsius to 65 degrees Celsius and in order to determine the amount of heat that has to be supplied, we need the heat that would be absorbed by the baby bottle. First, we need to know the material of that baby bottle which, for this case, is made up of glass since we need the specific heat capacity of the material wherein for glass it is equal to 0<span>.84 J / g C. We determine the heat as follows:
Heat absorbed = Heat to be supplied = Heat transferred m C (T2 - T1)
Heat transferred = 50.0 g (0.84 J/ g C) (95 C - 22 C) = 3066 J</span>
Answer:
A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.

Answer:
The trick here is to realize that the nitride anion, N3− , is isoelectronic with neon, Ne , the noble gas that shares a period with nitrogen, N . In other words, the nitride anion has the same number of electrons as neon.J
