The entire mass of a black hole
Answer: A
Explanation:
This means that the atomic number decreases by 1 but the mass remains constant, meaning the atomic number of the new element is 20. This corresponds to calcium.
10. Capital C and D represent products of chemical reaction, the capital A and B represent reactants, <span>the lower case letter represent coefficients (how many atoms or molecules in chemical reaction).
12. According to </span><span>Le </span>Chatelier's principle (if<span> the concentration is changed, that will shift the equilibrium to the side that would reduce that change in concentration)</span> <span>the equilibrium shift to the left.
13. </span>According to Le Chatelier's principle the equilibrium shift to the right.
14. According to Le Chatelier's principle (<span>When the reaction is </span>exothermic<span>, heat is included as a product)</span> the equilibrium shift to the right.
Soil is made out of all of these things and covers almost all landmasses. Even below sand and rock there is soil.
