I believe it is 2 because it is H2O
Answer:
Soil microbes are also important for the development of healthy soil structure. ... Soil microorganisms are both components and producers of soil organic carbon, a substance that locks carbon into the soil for long periods. Abundant soil organic carbon improves soil fertility and water-retaining capacity.

Using the atomic weights, K = 39, O=16 so KO2= 39+32=71. So K=39/71= 0.549 of KO2 and O2=32=0.45KO2 and O2=8g and 0.45KO2=8g so KO2=8/0.45=17.77g. So to check, K=0.549 x 17.77g=9.76 and so K+O2= 9.76+8g=17.76.
I the HCI is the mass of the equation but not always answer is Mg+HC H20
Answer:
What best describes the concept of weight is the force on an object due to its mass and gravity.
Explanation:
Weight is the force with which gravity pulls a body or object towards the earth. It is a physical unit that involves both the force of gravity and the mass that an object has.
In general, the terms mass and weight are different, being the mass a characteristic of the body -without influence of other factors- and the weight is the force with which the gravity pushes the mass of that same body.
Regarding the other options:
- <em>The amount of space an object takes up
, corresponds to the volume of a body.</em>
- <em>The amount of matter in an object
, corresponds to the mass.</em>
- <em>The force on an object due to its speed and location, is related to the movement of a body.</em>
