Answer the following question given this paragraph: Solubility is normally expressed in g/L of saturated solution. However, solubility can also be expressed as the moles per liter. Molar solubility is the number of moles of solute in one liter of saturated solution. In other words, the molar solubility of a given compound represents the highest molarity solution that is possible for that compound. The molar mass of a compound is the conversion factor between solubility and molar solubility. Given that the solubility of Zn(OH) 2 is 4.2 10 -4 g/L, the molar solubility can be calculated as shown below:. Q: The conversion factor between solubility and molar solubility of a compound is known as what? Choices: - mass effect - stochastic mass - molar value - molar mass A:
**Answer**
molar mass

Answer the following question given this paragraph: Figure 18.13 The honeycreeper birds illustrate adaptive radiation. From one original species of bird, multiple others evolved, each with its own distinctive characteristics. Q: What kind of radiation is observed in honeycreeper birds? Choices: - spontaneous - symbiotic - destructive - adaptive A:
**Answer**
adaptive

Answer the following question given this paragraph: A solution of cobalt chloride in water is pink due to the presence of the solvated Co 2+ ion. If sufficient HCl is added, the solution turns blue as the CoCl 4 2- ion forms. The reaction can be shifted back to the pink form if more water is added to the solution. Q: What causes cobalt chloride to turn pink? Choices: - discussed 2 + ions - show 2 + ions - h20 + ions - co 2+ ions A:
**Answer**
co 2+ ions

Answer the following question given this paragraph: The hypothalamus is actually part of the brain (see Figure below ), but it also secretes hormones. Some of its hormones that "tell" the pituitary gland to either secrete or stop secreting its hormones. In this way, the hypothalamus provides a link between the nervous and endocrine systems. The hypothalamus also produces hormones that directly regulate body processes. These hormones travel to the pituitary gland, which stores them until they are needed. The hormones include antidiuretic hormone and oxytocin. Q: What organ is the hypothalamus a part of? Choices: - Nervous system - liver - heart - brain A:
**Answer**
brain
