Three isotopes of silicon occur in nature. 28Si (92.23%), which has an atomic mass of 27.976 amu;

29Si (4.68%), which has an atomic mass of 28.976 amu;

30Si (3.09%), which has an atomic mass of 29.973 amu.

Calculate the atomic weight of silicon

i think it is true since you can test the answer and can use observations to complete it.

answerapplication program;

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
