M[(NH₄)₂SO₄]=2A(N)+8A(H)+A(S)+4A(O)
M[(NH₄)₂SO₄]=2·14.0+8·1.0+32.1+4·16.0=132.1 g/mol
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>
Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2).
Answer:
it is metals, it is the most prominent type of element on the table
