Iodine Strontium Silver...... ..I think.
You multiply 32 by 2, since there are two hydrogens in every water molecule.
B , Biosphere is a special shell of the Earth inhabited by living organisms
There are two kinds of mixtures
a) homogeneous : the boundary of the two components is not physically distinct
b) heterogeneous:the boundary of the two components is physically distinct
the following separation techniques are common for mixtures
1) filtration: if the two components are forming heterogeneous mixture we can separate them by filtration.
2) boiling: if boiling point of one of the components is less than other
3) magnetic separation: if one of the component is magnetic
4)sieve method: for solid components with difference in size of particles
5) hand picking
Thus the correct match will be as shown in the figure
Answer:
B
Explanation:
Biotic factors are alive. Some examples include plants, animals and fungi.
The “a” in front of abiotic will negate the meaning of the word. Therefore, abiotic means not living. Some examples are rocks, water and air.
So, we know that biotic factors are living, and abiotic factors are not living. Therefore, B is correct.
