Example
H2SO4
H = 2 atoms
S = 32 atoms
O = 4 atoms
atomic mass :
H = 1 u.m.a
S =32 u.m.a
O= 16 u.m.a
H2SO4 = 1 x 2 + 32 x 1 + 16 x 4 = 98 g/mol
hope this helps!
Answer:
Isotopes are atoms that have different number of neutrons, so they have a different mass number than the other atoms in an element.
The answer is C. No all cells have cell walls. Prokaryotes don’t have a nucleus or chloroplast. Leaving C to be correct
Answer:
Silver.
Explanation:
Hello!
In this case, we can consider the specific heat as the property that we can analyze in order to answer to this question. In such a way, as the specific heat is known as the energy required to modify the temperature of 1 g of the substance by 1 °C, since the masses of all the substances are the same, we can that their specific heats are respectively 0.240, 0.444 and 4.184 J/(g°C), from the equation:
We can see that the higher the specific heat (Cp) the lower the change in temperature considering their inversely proportional relationship. However, as 100 J of energy is applied to all the substances, we can see that silver will exhibit the largest temperature change because a higher change is needed to fit with the provided energy.
