Answer: The empirical formula is H2SO4 only.
Explanation: Because it is the simplest ratio of atoms of elements in a compound.
It causes the water to evaporate from the earths surface so that it can cycle through again
The answer is: Soft solid rock
Answer:
The answer is b) Less solid will disolve, because the larger value of [OH]- will cause the equilibrium position to lie farther to the left.
Explanation:
According to the reactions:
Ca(OH)2 = Ca2+ + 2OH-
NaOH = Na+ + OH-
The balance in the less solid solution will shift to the left, to keep the sodium hydroxide concentration in balance. This is produced by the common ionic effect in both reactions due to hydroxide (OH-) ions that are created due to sodium hydroxide NaOH, therefore, the solubility of calcium hydroxide Ca(OH)2 will be reduced. In conclusion we can say that the balance in the reaction will be more to the left.
Question number 1: Osteoblasts are a group of cells that helps grow bone tissue. These cells are converted from mesenchymal stem cells.
Question number 2: Having high amounts of collagen in the broken bone indicates that the broken bone is hard and strong. High amounts of collagen mean high bone tensile strength.
