Answer:
Now u have 48 g of O2. There. Fore mole=weight/M. W. Of oxygen. Therefor 3mole.
After that if we to multiply the avogadro number with it. So 3 *NA
Now u want only atom calculation then we have 2 molecule of oxygen then multiply it with 2 too.
So final claculation is =3*2*NA.

Everything has chemical properties it depends on the reactivity and the reactivity of the other element and what form it is in
Answer:
Granite
Explanation:
The specific heat capacity of a substance, which is denoted by "c", is the amount of heat required to raise the temperature of a particular mass of that substance by 1°C. It is calculated as follows:
c = Q ÷ m∆T
Where;
c = specific heat capacity
Q = amount of heat (J)
m = mass of substance
∆T = change in temperature.
According to this equation and explanation above, a low specific heat capacity means that the rate at which the temperature is raised is slow and vice versa. Hence, from this question, GRANITE with specific capacity of 0.790 J/gK will raise temperature the slowest.
There are four. Fe, H, C, and O
The formula for Nitrate is NO3-
