(a)
Interpretation:
Lithium nitrate is soluble in water or not is to be determined.
Concept introduction:
A solution is a combination of two parts: solute and solvent. A solute is the substance that is present in small quantity and solvent is the substance in which solute is dissolved. When water acts as a solvent then it is known as an aqueous solution.
A compound is soluble in water when the forces between the ions or atoms of the compound and ions of water molecules are greater than forces between the ions or atoms themselves in a compound. Ionic and polar covalent compounds are soluble in water.
In an ionic compound, the ions get separates in the water and form cations and anions. The positive end of water is attracted towards the anions and the negative end of water is attracted towards the cations. The ions get hydrated and the compound dissolves.
In polar covalent compounds, the atoms get polarized in the water molecule and become partially positive charged and partially negative charged. The positive end of water is attracted towards the partially negative charged atom and the negative end of water is attracted towards the partially positive charged. The atoms get hydrated and the compound dissolves.
In nonpolar covalent compounds, there is no electronegativity difference between the atoms so there will be no polarization of the compound. Therefore, these compounds will interact less with water and are insoluble in water.

However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…arrow_forward
